I run 30, though on my last road trip I bumped it up to 32 since the tire monitor sensor lit up a couple times (though historically it wouldn't come on until down to 25, which is the documented level).

You definetely don't want to go over what the tire's maximum is, and I think my factory tires only goes up to 44. Filling to 45, then when it gets hot, would be well over the limit.

Goodyear Eagle F1 GSD-3's here.

Run 35 PSI all around - best compromise of ride and handling (handling being the most important!).

 

i have a set of the forged coupe wheels on my sedan think i should run coupe psi specs?

 

Man, this question is like asking what oil do you use. You will get all kinds of answers. It depends on driving style, preference for mileage or performance, type of tires on the car, etc. There is no correct single answer.

 

Depends...if they are the same size wheel and tire run the sedan psi specs. The tire pressure depends on the weight and distribution of that weight from front to rear. My guess is that the coupe is lighter and maybe has a little more bias to the rear than the sedan. If they are larger wheels/tires you may want to try the coupe pressures, or a couple psi more to the front. Have to look at the difference between coupe and sedan to be specific.

will do i havnt even checked them

 

Actually the sedan is lighter and more rear biased than the coupe.

 

wasnt being a jacka$$, just stating a fact. I've changed over 1500 tires in the last 2 years and have never ran any of them over 35 unless its a truck/suv. If you can feel the difference between 32 and 35 you're nuts.

stock 17" Bridgestone (yes they suck, but I'm waiting for tread to wear then replace)... I run on 30psi always all the way around. Frequent spirited driving - decent handling (considering the sh!tty performance of the tires) and good comfort/ride.

BTW, I use to run 32 and that provides very comparable to above stated.

Maybe I should bump up to 45 to wear the tread faster. (j/k of course)
