@beerman1957 Yes! we should have a new bicycle vid. posted in a week or so. We have been able to remove 8 oz. from the aluminum wheel because the hoop is so strong. We are about the same or less wt. as a Stans 29" tubless.
@EnergyReturnWheel with a bigger rim can you make them into like a low profile? And are they heavy? I know there like empty in the middle but like just curious?

@onggabbo We want your wheels/tires lighter weight and to never go flat. Anit bounce for control. Go further on your tank of gas. Call Goodyear "alot" and request your ATV ERW. We would love to work with them!
@jts051686 We have made 7" ERW protos. Lightweight ERW bicycle project can be applied to smaller wheels. We do seem to loose a small % of downhill coast speed... we believe it is the deweighting effect reducing the pull of gravity. We out coast pnu. uphill.
@hustleunion We wish. We still need and should have to pass every hurdle. We need DOT approval, we have been addressing all performance issues in the patent office and proto development.
@96camaro3800II Freedom of choice is a good thing. Tires still rule with 100 years development advantage. Like a 6 mo. baby going against a 20 ft. python we still have some growing up to do.
I personally think something like this would be great on aircraft. The VLJ category is booming and new innovations to reduce overall aircraft weight are where the majority of the focus is. Reducing the weight of an aircraft ounce by ounce increases not only the efficiency, but the value of as well. I would definitely do some research to see how practical a system like this could be on a light jet.
@AeroSharkTech Thank you. Our "airless" lightweight bicycle project has shown us ways to further reduce "rubber" mass. Rubber is the weakest link. Take off rolling resistance improvement, "anti bounce" to stick the landing.
@TheIronz A few keen eyes have spotted the "wrong way" directional tread. For the first 2 ERW home built auto proto we were happy enough to support the vehicle weight and be able to drive around the block without anyone noticing. We were not high performance ready so the tread was just to keep the old style "steel" off the ground.
I would prefer if the sides of the "wheel" were closed up to reduce mud/snow etx build up. But that is only because I live in those conditions.. Looks promising. dont forget to test them in extreme conditions though!
@69r0xx We have highly elastic sidewalls that can hold a vacuum boost, accumulate/return screw force pat filing #4. Extreme conditions survival/performance will benifit from a true run flat for sure. We are working hard to earn your respect!
@Monkriss ERW would rather roll than bounce. Lift a car by the bumper. You can raise the 2 ton chassis several inches because the mass is stored in the springs. ERW hub is suspended within the hoop and is displaced by the pull of G like the suspension system. No matter how it is explained we are still the most efficient coast down.... tire vs "airless" ERW on youtube.
@flyingtigre1 Try this experiment. Place a rubber band against your lips, stretch and recoil. Rubber heats up while you stretch and cools when recoiling. We have a patent pending on applying this recycling potential to our traction systems. We roll a Tri Pod footprint, less tread squirm, true tracking, more efficient.
@flyingtigre1 This was not our intent. We are simply discribing what we believe ERW will bring to the future transport system. We have no way of knowing what patented/pending ERW tech. will eventually show up so for now we are about offering research choice to the industry. We are sharing alot of what we are discovering.
This sounds to be a completely non cost effective idea. how much do these cost to make with them being made from lots of differant parts? a normal wheel has 3 parts tyre, rim and a valve. how many does this thing have? how long will the tyre last cos there must be a high wear rate due to the hard contact between the road and the tyre unlike the cushioned tyres we have today?
@planetrob555 If you are talking of the pnu. tire we know that they "only" loose 25%-40% due to sidewall and treadblock deformation depending on vehicle weight. Our coastdown video just suggests we loose less/return more.
@planetrob555 Thank You...cool, we have tough days too... we can relate. Going green is not so easy with tires. We hope you enjoy the journey with us. Hero or goat ERW will be entertaining.
I built something like this 20 years ago and never filed a patent because you lose so much traction and introduce so many extra points of failure it is a worthless design. Good job idiots, you made a copy of a failed design based on omish wagon wheels.
@keystothebox Yes, you're right. Nevertheless, these wheels can be useful, for example, in the army. If we consider shortcomings, it is still important protection against punctures.
@keystothebox The Egyptians had them on their chariots 5,000 yrs. ago.. This is a tough starting point IE the long list of performance requirements of todays world. We have found the traction solution and have eliminated points of failure. Our membranes can now be as strong and light as Kevlar.... because they are made of Kevlar.
@watchthisrobotmove Newest and best always comes at a premium. For our prototype construction we hold nothing back. All materials are space age composites that we have enhanced via nano technology. We are looking to robotic molding production... ERW can be constructed anywhere. We hope with less costly materals but there is always a market for high end high performance product to support development for the masses.
I'll bet the grip with these tires are horrible. The grip these offers are probably on the same level as low profile tires, if not worses. And the problem with low profile tires is that they can't absorb bumps, cracks and such in the road as well as normal tires.
There's a reason why race cars never use low profile tires; they're crap.
@CutthroatBill You are right about the sidewall height "formula 1" good example. It has been a real struggle to increase the footprint size and psi. to the surface to mimic the 'best" of pnu. road feel and grip. We have just filed 2 new patents discribing how we do it.
Your design has many more potential random hardware failure modes than a pneumatic tyre which increases hazard risk. Have you conducted a formal hazard analysis?
@redwhiteblue91 Pnumatic tires loose about 30% rolling efficiency from sidewall deformation and treadblock. Under or over inflated tires can be dangerous, can go flat at the worst of times or places and can cause loss of control from the result of "finding" a 1" wood screw.
@mubd1234 We have 2 China pats already issued, with more on the way. Protection from piracy for China manufacturers who invest in molds and equipment. Protection for US as the global tire industry looks for the China production cost advantages.
This has so many flaws already pointed out so ill just go with, in the United States this would never be allowed to be a "road legal" tire seeing as the police wouldnt be able to toss a spike strip under it and have the chase come to an end.
@redhothitsng Tire vs ERW vid 35.5 psi. tire vs early ERW. Contrast how fast they spin up and coast down under a massive 6,000 dyno load on 48" USDOT lab dyno.
so if i was foolish enough to purchase a set of these for my truck, and I seriously doubt a model is made that can carry the kind of weight it would put on the wheels, i would now need to use a socket wrench on a hundred bolts to change a worn tire, as opposed to an air powered tool on 8 bolts. Long story short, this video says "pay us lots more money for reduced functionality and more inconvenience"
@cummins24421 The promise of simple ERW is coming true. We believe that our new vacuum install/removal process is close at hand. No bolts. This can only be accomplished if you have our hoop ridgidity. Highly elastic patent and "pat pending" sidewalls hold a negative air pressure or vacuum boost. Will run w/o vacuum, vac. for fine tuning, weight reduction, compressed air is heavy. Aprox. 2 lbs @ 30 psi. with humidity.
@EnergyReturnWheel and the load bearing capacity? my truck weighs 9000lbs before fuel, passengers, cargo, etc. also needs to be capable of towing a 10000lb trailer without a 5th wheel adapter. high abuse applications are the perfect target for this sort of wheel because it eliminates the risk of puncture as well as sidewall failure.
@domanikj Chuck Norris is a good role model for sure. Now you have us all thinking how cool a Chuck endorcement could be. We have to develop ERW until they are "Chuck Norris approved"!
he dident really "do" anything...atleast from what is see and understand...all he really did is remove the air and make it a shittier ride...i woner what happens when you try to do a burnout..or even takeoff really quick...i think you would bend or snap the bolts.
@deltajegga Check out our "tire vs ERW" video to see a "chained down" AWD ML 55 AMG "spin" a USDOT lab dyno set to 6,000 lbs. resistance. We now have improved IE simplified protos. Check out our first on the ground carbon/Kevlar vid, to show ride cushion from 1 1/2" sidewall ERW accending 1 1/2" stone. A bit too bouncy so we went back to hoop tech. Filed 2 more pats covering "new" hoop tech.
@Micbo2k10 Big wheels keep on turning. Larger diameter, aprox. 30% lighter hub and rim because the composite hoop is so strong.... the hub just floats / rides inside.
Nice idea. (BUT) Just like the assinine super low aspect tires on the road today get ready to have your teeth rattled out of your head. A majority of road impacts are absorbed by the flexing of the tire. It appears that with this tire you will be able to count every grain of sand you run over. Also how about some test data on the results of hitting a pothole at 60 mph. The likely result is you will be bringing your suspension home in a bucket. I could write pages on whats wrong with this THING.
So you'd gone back to the basics of a wagon wheel... Well I guess this is how technology goes lately.. Just like all those "rocket stoves" which have been used for centuries and yet people are "rediscovering" them.
I don't recommend it. What if there's a deadly pursuit and criminals were using this in their vehicle? How will you stop the vehicle when you can not deflate the tires using spikes?
With all that force directed inward, wouldn't this design require maintenance often? Like tightening all those bolts on the inside?
Also, this is a useful design, but for consumers to buy it, it needs to look a bit more attractive. If you can find a way to cover up the gap and make it appear as a regular tire, more people would be willing to purchase the ERW
@StealthNinjaX2 No bolts. We have found the better way for auto via bicycle proto development. We have mentioned that the look has changed much with our highly elastic sidewalls or our full body dynamically charged hoop designs. We are always looking for ways to simplify, improve.
Don’t get me wrong, as an aerospace engineer, I see this as a great idea but I see a lot of problems that should be addressed. One of the problems is the stress life of the “spring steel hoop”? I can see the steel hoop fatiguing considerably fast. I also see that hoop deforming easily under heavy acceleration.
@engineerFROMhell We switched to space age composite carbon nano tube infused carbon fiber woven hoop with nano infused Kevlar jacket. Check out USDOT lab tire vs ERW vid. for 6,000lb. dyno load acceleration/coast down...notice "hub in steel hoop" floating high and foreword under throttle responce.
I would think you could do a little better then researching an idea of replacing the tire with your SHOE SOLES.Your direction is to too focused on that and not of the actual concept you are portraying.Maybe if you made an inner hub assembly that did the same yet keeping the tire pneumatic it will still utilize the same energy concept.Sure did not re invent the wheel on this one though.Maybe re invented the tire..
@muggzshotz How about checking out our other vids. before you decide what we are doing. The patent offices around the world do not agree with you. Our patents are all classified under utility wheel patents. Aproaching 100 independant claims!!! Our R+D is the envy of the tire industry. Check out other "airless" Michelin Tweel or Honeycomb patent portfolios for a contrast.
@EnergyReturnWheel No documented data either,the dyno runs are not showing use or non use of the brakes or data,notice the standard wheel and tire has a little stumble at the end leading me to thing use of brakes as of your concept piece did not and I find it unpractical in cost to purchase or even service this concept in the real world.Too many variables,TOO MUCH HARDWARE = too much risk..
@muggzshotz All tests were performed by USDOT lab tec following their protocol. We now have simplified designs. The highway test has brake lights show as lab tec. must apply brake force to keep to protocol IE we overshot the coastdown portions by more than 20% with brakes applied.
@dasKeks28 We are looking at producing a less costly co molded product. This is why we continue to refine. On the high $ end...our uber light weight bicycle composite protos look "wet" because of the carbon nano tube resign gleem. Worlds lightest 29" MB wheel, assembly, ERW video to release soon.
Congratulations for using spring effects to your advantage. Now go on and make those spring things and the membrane not wear out too fast. If you have fixed that go on and make the ride comfortable. Then take the beautiful AMG E 63 to the Nürburgring, drive a lap below 9 mins. If you have done that you can brag and tell the world how awesome this is. Honestly I am an engineer from the "motherland of engineering" and I dont see how you deal with forces during turns, I guess not with bolts.
@donerdoner1234 We use a vacuum pressure on the hoop side of the membrane to increase power and longevity. We have pioneered a composite hoop so light and strong that the hub can be massive 30% lighter. We have a totally new traction system to bring higher psi. to surface. ERW is anti bounce because it displaces internally. Hub in hoop 360 degrees freedom of movement under drawn membrane control. Camber issues are addressed by the new "curved body" hoop with Kevlar bound rubber wedges off curve.
i was thinking exactly the same: how many G's can they hold, how long will they last, how much grip does it have when driving a wet track and how much heat can they hold?
@PipiMetKaka We hope 2012 is the year we can pull all the best qualities of each improving prototype. We can tell you this much... you will not be disappointed.
@donerdoner1234 Thank you for pointing this out! i was so frustrated watching this video... I'm all for innovation, but this guys blatently said- "I have re invented the wheel" lol...Notice how the creator of this replied to the above comments which were posted in the past 6 hours, yet he has not acknowledged this post from 4 days ago. Also, the rubber on these toys likely costs more than a standard tire and rim.
you dont address the "loss of traction... losing lives on the highways" bit at all... "part of the car that will not need to be replaced", really, you still have rubber, on concrete, that shit wears out... all you are really doing is creating rotational weight which could save gas mileage, but i doubt that much, and require more braking force thus having to replace break pads more often
@spencerjustin420 Tire safety is a real issue. Debris on the road, under inflated or even expired tires can create life changing accidents. It is our goal to introduce a high speed airless that will not be taken out by a 1" wood screw. Composite ERW even can survive multiple high power rifle shots and still get you where you need to go. The early proto rotational mass has nothing to do with ERW performance. Newest protos composite hoops and traction system are lighter than pnu tread block.
That is crap!!! Didn't you hear about don't reinvent the wheel. So many bolts so many more points things can go bad, these wheels are but-ugly!!! How about a car going from 0 - 60? With and without the wheels? I'd love to see that. And you mentioned springy - I'd love to see how well it stops a car from 180 Km/H. How about that huh, how about it? Show us the wheels in action not on a fancy car crawling around, until then you will forever have sceptics (like myself).
@BKamron Thanks for your words of encouragement. We have protos with no bolts. Check out our USDOT coastdown tire vs ERW where you can see acceleration and coastdown under a massive 6,000 lb. AWD dyno load. ERW crushes pnu. while DOT lab. tech. follows protocol.
Interesting all the thought going into this concept, however, at 1:20, you are mounting a unidirectional tire backwards onto the car (or on the wrong side of the car, however you want to look at it).
@katnyp99 Did not matter for the first 2 home built auto protos. We were only looking to support the vehicle weight with very little performance requirements. When inventing the big requirement is to make protos without costing big bucks. Then build from the foundation.
@MrTheLemonn For these early protos each "pull" is drawn with about 300 lbs. linear tension. Upon throttle responce ERW can accumulate screw force, Hub can rotate within the hoop elongating the membranes like a wind up airplane increasing power transfer to surface. Each bolt can easily support 300 lbs. lateral shear suggesting 300 lbs. x 36 attachment bolts = no problem. We have moved away from bolt attachments for auto but they will show up in some heavy duty applications.

Sure its easy to think of an invention when you're already rich enough to supply yourself the materials, only to be come more rich...god I hate rich people, lol.
i'm sorry, but this does not add up. the bolts inside, the rigid // springy rim inside and the "membrane". you 've the patents, now give us some science. cause, far as i can see, there is no actual gain... i don't mean to sound cocky, but this video is a great infomertial... and that's it. i'd like to have a bit more inside data, gmeters, mileage gains, actual stress tests and, finally some detailed -REALLY DETAILED- exp on how it works. i'd love to see this working the way you say it does. thx!
I feel it is a great idea and can be used in many different applications but how much longer will we have personal vehicles that use wheels? Believe me I love automobiles but it is a fear of alot of us that inevitability will come to reality.
His lack of direct straightforward answers to the advantages of these tires tells you several things.
1. They are a gimmick
2. They are just a variation of the standard pneumatic tires not a "reinvented wheel"
3. He's just looking for big $ backing so he can get rich quick.
These things are obvious and it just looks like a tire skin an a rim with a bunch bolts which = 100s of more points of failure than a standard pneumatic tire. This just proves you can overengineer anything.
@Boomersays Yes... We have been getting "rich quick" by investing our own money for the past 10 yrs. ERW is not your Government grant or loan money project.
@brandieism We will have a sealed dual vacuum charged "compressed air is heavy" ERW for off road racing. We can now cut a staggering 30% of the mass of a large tire wheel combo... "high speed airless" still runs w/o vacuum boost.
A BURNOUT WOULD BE COOL! :)

@TheIronz A few keen eyes have spotted the "wrong way" directional tread. For the first 2 ERW home built auto proto we were happy enough to support the vehicle weight and be able to drive around the block without anyone noticing. We were not high performance ready so the tread was just to keep the old style "steel" off the ground.

@Monkriss ERW would rather roll than bounce. Lift a car by the bumper. You can raise the 2 ton chassis several inches because the mass is stored in the springs. ERW hub is suspended within the hoop and is displaced by the pull of G like the suspension system. No matter how it is explained we are still the most efficient coast down.... tire vs "airless" ERW on youtube.

@flyingtigre1 Try this experiment. Place a rubber band against your lips, stretch and recoil. Rubber heats up while you stretch and cools when recoiling. We have a patent pending on applying this recycling potential to our traction systems. We roll a Tri Pod footprint, less tread squirm, true tracking, more efficient.

I'll bet the grip with these tires are horrible. The grip these offers are probably on the same level as low profile tires, if not worses. And the problem with low profile tires is that they can't absorb bumps, cracks and such in the road as well as normal tires.
There's a reason why race cars never use low profile tires; they're crap.

@cummins24421 The promise of simple ERW is coming true. We believe that our new vacuum install/removal process is close at hand. No bolts. This can only be accomplished if you have our hoop ridgidity. Highly elastic patent and "pat pending" sidewalls hold a negative air pressure or vacuum boost. Will run w/o vacuum, vac. for fine tuning, weight reduction, compressed air is heavy. Aprox. 2 lbs @ 30 psi. with humidity.

@EnergyReturnWheel and the load bearing capacity? my truck weighs 9000lbs before fuel, passengers, cargo, etc. also needs to be capable of towing a 10000lb trailer without a 5th wheel adapter. high abuse applications are the perfect target for this sort of wheel because it eliminates the risk of puncture as well as sidewall failure.

Nice idea. (BUT) Just like the assinine super low aspect tires on the road today get ready to have your teeth rattled out of your head. A majority of road impacts are absorbed by the flexing of the tire. It appears that with this tire you will be able to count every grain of sand you run over. Also how about some test data on the results of hitting a pothole at 60 mph. The likely result is you will be bringing your suspension home in a bucket. I could write pages on whats wrong with this THING.

I would think you could do a little better then researching an idea of replacing the tire with your SHOE SOLES.Your direction is to too focused on that and not of the actual concept you are portraying.Maybe if you made an inner hub assembly that did the same yet keeping the tire pneumatic it will still utilize the same energy concept.Sure did not re invent the wheel on this one though.Maybe re invented the tire..

spencerjustin420 1 week ago
@spencerjustin420 Tire safety is a real issue. Debris on the road, under inflated or even expired tires can create life changing accidents. It is our goal to introduce a high speed airless that will not be taken out by a 1" wood screw. Composite ERW even can survive multiple high power rifle shots and still get you where you need to go. The early proto rotational mass has nothing to do with ERW performance. Newest protos composite hoops and traction system are lighter than pnu tread block.

MrTheLemonn 1 week ago
@MrTheLemonn For these early protos each "pull" is drawn with about 300 lbs. linear tension. Upon throttle responce ERW can accumulate screw force, Hub can rotate within the hoop elongating the membranes like a wind up airplane increasing power transfer to surface. Each bolt can easily support 300 lbs. lateral shear suggesting 300 lbs. x 36 attachment bolts = no problem. We have moved away from bolt attachments for auto but they will show up in some heavy duty applications.
