How much tire pressure and grill block question

[IsaacCarlson]

If they are rated at 51 psi, they are probably goodyear fuelmax. We sell them at work and I believe the only difference is the pressure rating. We don't sell many.

I do 90 deg corners at 35mph on my cobalt at 50psi, it seems like it corners better not worse.

I feel better about how my car drives when its 44psi.

Tire burst is well over 100 PSI. It might be a problem if you have really, really low quality tires or if your tire is damaged. Don't worry if your tire is a few PSI over max sidewall. You are much more likely to have problems with underinflation than overinflation.

My tires are at 65 PSI, at the moment, or they were a month ago before it got cold.

Good last point, Sulfuric. It's time to check your tire pressure! Even if they were a little high last month, they're likely underinflated now.
