Optimal tire pressure for 19,s in twisty sport driving?

**motoadve** · #1 (**permalink**) 04-19-2008, 02:09 PM

Twisties mostly 2nd 3rd gear, 19inch wheels.
What would be the best pressure for most grip when cornering?
Tires are Michellin Pilots

On road, I'd use manufacturer's recommended 32 front, 37 rear unless your door sticker says otherwise. On track, I add +5 to fronts and +3 to rears to keep from rolling off (and wearing out) the shoulders, and my tires wear pretty consistently straight across while giving excellent grip.

After much experimentation, I set to 32F/36R cold on 18's.

On my Bridgestones, on the street I bump the fronts 2 psi from the recommended to try and cut down on the understeer, i.e., 34f 37r. Works for me, YMMV.
