 How many times would you change the tyres on your car at home? You might be lucky to change a set every 24 months. Well this weekend our East Coast Bullbuzz Australian Championship teams will use 24 over the weekend and they're restricted to that. So why is it so important to put the new tyres on and what does it mean for the drivers and the teams? You know as you can see with the two tyres here we have a brand new one and a used one. This has just come off after 50 kilometres and you can see all the blocks here of a worn away as opposed to a new one. These inside blocks create a lot of where we when we brake and give us a lot of feeling under the wheel where these outside edges here as you can see there it's almost non-existent on this tyre and this one is the shoulder is there which gives us a lot of feeling through the steering wheel especially when we turn in as these wear away you find the car really turns to understeer and you're losing that grip also as you know the middle part of the tyre goes away acceleration goes hence a lot more wheel spin so a lot more gear changes. When you go from something like this old one to a new one it's almost like a brand new car the feeling is unbelievable and of course for us grip is speed in this sport. That's right grip is speed and you know for us as a driver it's all about confidence too so when you've got to putting the power down and when you need to you know you're leaning on the tyre and the tyres working you have a lot more confidence as a driver. That's right although that may all stand a little extreme the same principles apply for your road tyres.
