Re: Proper Tire Inflation for 18" vs 17" (R Salesman)

~41 is what I use with the PS2's. rear sometimes ~40.

The PS2's need it, the PZero's start to hammer a lot with these pressures.

WAY too high.
We can argue this to death but Volvos HATE high tire pressires, all they will do is rattle apart.
I used 33-34 with 17's and PZeros
I use 36-37 with 18's and Michelin PS ALL SEASONS
I would go with 34-35, maybe 36 tops with 18's and Pzeros.
Michelins seem to want a couple of pounds higher pressure than Pirellis (softer sidewalls)
I forgo "ultimate" handing for a nice ride and good tire wear you WILL wear out the centers if you go 39-41 lbs of pressure
All pressures are cold, of course

Not at all, and you are actively promoting unwanted tire blow out..
