Re: 2004 zx10 tyres and pressures

Ok... I guess you didnt ever study practical mathematics (and at that, physics). So are you saying that if I'm doing a track day and its 30 degrees, I want to INCREASE the pressure and if I'm doing the same on a COLD day, I need to LOWER the pressure?!zxsixr03 wrote:
Dude where the fuck did u get your info from??
In colder temps you want lower tyre pressure as what heats up a tyre is movement in the wall of tire hence a lower pressure gives more movement and flex and allows a tyre to warm up quicker and to correct operating temp.
On hotter days vis versa, add more pressure but no more than recommended as you want less flex and the tyre will heat up just the same due to road temp and air temp and some flex in the tyre.
Please do some research before you go feeding people asking for the correct info a BS theory.
Read what you are saying 5 times before you ask me where the F I get my information.
Its simple, less air will expend due to heat to a lesser amount (read pressure). Lower pressure might increase contact patch size but will reduce rigidity of the tyre affect handling.
Why not run your tyres at 10 PSI in the cold, I'm sure your contact patch will be large as well as the tyre's ability to heat up!!
Buy a book on physics, start at Physics for Dummies.
Edit: From the Michelin Site:
Tyre pressures?
Inflation of winter tyres :
The ambient temperature has an effect on the tyre pressure. The lower the temperature, the lower the pressure. Therefore, as it is generally cold in Winter, to compensate for the “low temperature” effect, and to drive with the right temperature, we must add 0.2 bars (cold) to the pressure for normal use or to the pressure for other uses at the right pressure.
