Tires?

[GasSavers_Danno]

My dinky little 13's from the factory are supposed to be pumped front to back, 31 and 29, accordingly. Now, what would YOU guys recommend for higher mpg?

Which btw, im up to about an average of 29 now

What's the tire rated for? (look on the sidewall)

If you want safety then go for the max cold tire pressure. It's on the sidewall of the tire like SVOboy said. If your primary concern is mpg only then go 50-55psi. But remember with increased psi there is some loss of traction. Especially with 50-55psi.

Oops.. forgot to reply all this time :X

on the sidewall it says max 35 psi? so im going to fill up to 35 psi on all tires. so i cant really go more without busting a tire?

More, yes. I would go to 40-45psi if it says 35. Some people on this site would go up to 50-60, but that sounds a bit risky to me.

If your tires are brand new and you don't live around any pot holes, I would say you could go 20% above rated max presure, but as they age, and the rougher the roads you drive on, the more likely they are going to be to the bursting point.
also when you look at your tires, it states a max weight, at the max psi, not just a max psi, the more your car weighs, the more stress the tires are going to be under at a given psi, so if you have a light car that is way under the weight limit of the tires, I would say rasing the presure would be fine, but I would keep it within 20% of the max, and that is part of the reason for buying better tires, mine are rated at a max cold presure of 44psi, next time I'm going to look for ones that are even higher.

for me its 10% of sidewall pressure.

I have side bumps for the left of my front and a little on the rear but I turn left a lot with nasty bumps.

Feels hard as a rock!

I have read in numerous places that higher pressure increases traction. I am not suffering at all at 60 PSI. I don't remember where it was posted but there was an article about the San Jose Police department seeing better traction with pressure. Also there was a picture of a Ranger riding on two wheels with the pressure at 100 PSI.

I have read that numerous times. It was on a website for police officers. In the article it stated that the police cars only had the max sidewall pressure. They didn't go more psi for safety reasons. If higher pressure increases traction than why do people at the drag strips lower their tire pressure to gain traction???

I think i said this before, but don't drive with +45psi tirers in the snow! High presure in the snow is a bad idea.
