I do my best to keep my tires at 30PSI. I will admit to being lazy and letting them run down a bit. Nothing crazy. Maybe two to five PSI.

I know some folks like to run them at higher or lower levels and was curious to know why.

I know that lowering them is nice for the track, but for daily driving, do you like to stick to 30PSI or go lower/higher?

I was actually going to ask the same question. I just put new tires on mine and the tire shop put 40psi in the rear. Seems a bit high to me.

Dave68

40 is way too high. You should lower that pressure, immediately. I think the correct pressure depends upon the tire's construction. For example, 30 psi was too high for my OEM runflats, but the same pressure seems to be good for my non-runflat GSD3s.

30 psi cold is what I believe is recommended. I just purchased a new set of C6 Z06 chrome wheels. I forgot to check them as I was in a hurry to get them on the car as I was leaving early the next day for a trip to the central part of the state. I happened to check the pressures while driving, and one tire had built up pressure to 49 psi. I dropped the pressure down and the next day I set all of the tires to 30 psi.

i run 30 in front and back. that way you have good traction to mpg ratio

On the inside of the drivers door there is a sticker with the correct psi for tires...follow that. That should be the ideal pressure for street use. Indy

How about this tough... thats for a 17/18 setup.


I have 18x9.5s front and 18x10.5s back..
265/35/18 front & 295/35/18 rear

What should my pressures be (front and rear)?

Gideon's_Test

Not to be argumentative, but the driver's door sticker is a guideline and refers to the vehicle with OEM tires and standard loading. If you use a non-OEM tire and carry a lot of weight (or for those very light drivers) very little weight, the PSI can vary somewhat.

The factory value of 30PSI cold is a good starting point (and good enough for those of us not concerned about it) but to those that want slightly better gas mileage or better handling, a little adjustment can be of benefit.

No worries. I know 30PSI is what my Z wants.

Just wanted to see if others use different numbers and why.

I've always put a few extra PSI in most of my cars for a cushier(sp?) ride.

I'm running my stock GY runflats at 25-27 psi. I seem to be getting more even wear across the rears and the ride is less harsh. I suppose my mpg is a little worse but the better ride is worth it. If I were tracking it, the pressures would go up

you must not have your wheel sensors working. if my tires drop to 25psi it will let me know on the dash of low tire pressure....

Oldvetter

I run 30 psi in fronts and 28 psi in rears. Rears wore out in middle with 30 psi.

I get 45,000 miles from rear tires and 55,000 from fronts, using OEM runflat Goodyears.

Evil Twin, an ex-GM Corvette Engineer, says that 30 psi hot is the "sweet spot" for Corvette tires.

I try to go 30 psi all around

I am running 32 psi cold in non-runflats. I have been getting even wear and the car seems to handle better. I am on my 4th set of non-runflats and this has worked well for me. Three sets of Goodyear GS D3s and now running Bridgestone Pole Position RE050As.

Z0Sick6

anyone have a suggestion what i should run? This package is going on next week and would like the best handling for my car and traction since i have 550+ rwhp

Smoky2

I inflate 'em to 30psi cold. Then I'm running they get up to about 34 or higher.

I like the ride and handling at this pressure.

Jet-Jock

I try.

Cold weather keeps dropping the pressure on me.

C5XTASY

That should make for a rougher ride rather than cushier. Higher pressure means a harder tire.

30 PSI works great for me.

Interesting, I've been running 25-26 all the way around on the runflats?
