Yeah. With the 17" tires, Honda recommends 32 psig, I run mine 34 up front and 32 in the back because of the weight distribution. With 18" wheels, the recommended is 36 psig, again, I stagger my front and rear 2 psig, with 37 up fron and 35 in the back. Dunno what they recommend on the 16" wheel, I'm guessing something between 32 and 35 psig.
32 recomended. I usually run mine a few psi high as well, especially in the winter.
I know lower pressures are supposed to give you more traction but under-inflation makes it easier to hydroplane; I'd rather sacrifice some traction in this case.
Reviving old thread.
I've got aftermarket rims/tires. Tires are 235/45/17 Extreme Contact Sports. I've recently deleted the annoying direct-TPMS system, and I'm curious if adjusting my tire pressure from 35PSI can improve anything.
Only looking for slight improvements, as I can now run lower pressure AND turn off traction control.
Generally speaking, start with what the manufacturer of your car recommends and adjust from there. There is obviously a bit of wiggle room as you tune for how you are driving and any other changes that you have made (including tire size), but ideally, you want to monitor the wear across the tire's tread section to determine the best pressure. Too much pressure, and the tire will wear faster down the middle of the tread. Too little, and it'll wear excessively on the shoulders.
Sorry, but I can't give you a definite answer.
Stock recommends 32PSI on smallish 215/45/17 tires. I'm running slightly bigger 225/45/17 tires and bumped it up to 34PSI. I find 32PSI a bit too soft 34PSI is firmer so less flex when cornering but the ride is noticeably harsher and louder.
