I reread my post and realized that I should clarify the "unless you know better" remark.
The door sticker on my car says 35 PSI front and rear. I actually run 35 front, 33 rear. Why the lower pressure in back? It increases the contact patch slightly, which makes it less likely that my car will spin. 35/35 would work just fine for normal driving, but I've been known to get. . .enthusiastic. . on the twisty roads
BTW, my tires say 40psi. If I ran that, i'd lose grip over the 35/33 that I do run.
