Tyre pressures for porsche 996 turbo on track day

[tymwright]

Hello.

Can anyone suggest what pressures I should be running my tyres at for track day? Book pressures show 2.5 front and 3.0 bar for rear......think that maybe a little high..... Any suggestions?

Depends entirely on the tyre - some need to be increased, some need to be lowered. I'd start with them at book values then check them after the 1st session and lower them back to book values.

Thanks

remember and let them cool down at the end of the day and put some air back in.....don't want to damage them or have funny handling driving home

I was at Bedford on Saturday in mine (PZeros fitted) and dropped from the recommended 36f 44r settings to 33 / 40 when cool so the heat would bring them back up. I found this worked pretty well but the best advice is to go out for a session, see how much they increase from heat and compensate. Just remember to reset them at the end of the day before heading home.

Thanks for that. I will try these.
