I had P7 summer runflats on my X1 s28i M sport.

When it's hot the fronts would get over 42 psi which is no good.

40 hot is about max for front , and approx 43 hot for rears.

I didn't need to add 4 psi to the 35f 38r cold because the heat gets it too high already.

Of course the Pzero might act different.

If front doesn't grip you have too much in front tires.

I did my first track day on the stock Goodyear Eagle All-Season run flats, so you shouldn't have any problems.

Unless you are starting with a morning session I would actually drop your air pressure by 2-4lbs. Your air pressure will increase as you get heat into the tires and this is where you want them running at their optimum pressure.

Big thing is to just have fun!
