Tyre pressures

IWANT1 · Post by **IWANT1** » Wed Aug 01, 2007 11:09 am

Is there a guide or is it just a trial and error to work out track/sprint tyre pressures!

About to run some colway tyres and have no idea of what pressures to run usually run 28-32 in my yoko A539's

Any advice would be appreciated

I would say that you should try the same pressures but you could always ring Colway and give them the weight of your car and see what they reckon. I'll have a tyre pressure gauge and mini compressor with me if that helps.

Lee what was the outcome from the sprint with regards to pressures??
The car got better as your day went on.
I would hazard a guess you lowered the pressure a little.

See my other thread reguarding the issues with the colways

For pressures in the yoko's i stated the day at 28psi but as the runs came together with shorter breaks they rocketed to 36 psi when cooling off so dropped them down to 28psi and they settled at that during the later runs.
Would have loved to have used the colways as i set the same time with them not being bedded in and stone cold!
