My car is just shy of 2400 lbs and I have been running them 36-38 max hot.
I will try the lower pressures to 30 hot on all four in Nov when back at Sebring and see how much the grip improves.
I would assume you start them around 24-25 cold depending on track temps?

Cheers,

Yeah, I just checked in the garage and mine are at 18F and 20R, which might be a touch low -- since the last track day saw 100°+ temps. But then, I'm back at the same track tomorrow, and it's supposed to be 95, so I'll probably see a higher-than-usual spike again. These are 255/275 width Nittos.

Thanks for the info Jack, if you dont mind let me know what you start them at to get to the 30psi hot and what the temp is tomorrow. This will give me a good starting point when I get back on track in November.

Thanks,
Greg
