SIT -- Self inflating tire

"SIT" is a newly developed, very simple, inexpensive and reliable system for Self-inflating Tires.

SIT is an integral tire component that uses atmospheric air to automatically inflate the tire. As a main source of energy it uses only wheel rotation, so there is no compressor or similar additional device needed.

This ensures maintenance-free, constant tire pressure over the lifetime of the tire, with great benefits.

It reduces tire wear, increase fuel economy, makes your drive more safe and steering more accurate.

Note: In the US alone, 4.5 million tires have to be replaced before their designed lifespan as a result of under-inflation. 87% of all tires have a history of under inflation. Poor tire pressure also costs US an extra $3.7 billion in fuel annually.

And now we just need the SHIT (Self Healing and Inflating Tire).

so much for running a little under or over pressure on purpose.

If it retails for cheap, I'd definitely use.

WOW! This is SO THE FUTURE

[95Gabe]

IF the valve gets damaged could the tyres over inflate and blow out?

[icicicles]

In a perfect world maybe but we have Rd greese mud and other

rd hazards that can plug up the system, wouldn't you say?
