Potenza tire pressure

The Potenza's are rated to max 44 psi.
I filled mine up to 40 psi, seems to be pretty good.

What tire pressure is everyone running on the 18's?

That tire pressure is way too high. It should be in the 30 to 33 psi range.

Goodyear, 205/50/18 is the size. The specs on the door plate say 30 PSI all around, so that's what I've been doing.

KMAN is probably right, although I don't have the Potenzas and can't say for sure. BTW, the sidewall "Max PSI" info on the tire itself is NOT the actual inflation pressure you are supposed to use, it is the highest pressure you can safely put in the tire. I always go with the owners manual, and when I replace with aftermarket tires (through Tire Rack) I ask a specialist what to use.

Just use what is stated on the sticker on the door jam, it tells you what the pressure should be.
