Tires Pressure

[drift_ricer]

Hi everyone, i have a 18x10 (front) and 18x11 (rear). I have 225x40 (front) and 245/40 (rear). I'm stretching these tires, so what is the good PSI for these tires. And i'm driving my car daily, please help me out. Thank you.

if i remember +15-20 psi more than the rating on the tire for streached.
so if the tires rating is 30psi add 15....

[nrg]

stretching has nothing to do with pressure. air is still taking up the same mass so the pressure is the same as if it's not stretch.

i run 38-40psi on ALL my tires/cars

I run 35 psi. Slight stretch on a 9" wide wheel. 225/45/17. I ran full pressure on a pair of 205/55/16s on an 8" wide wheel and the center of the tires wore down quicker than the other parts of the tire.

Fuck man, you guys are crazy.


55psi on both ends to start out with.


if it plows go to 50 in the back.

lol i know, 225 45 17, on a 9? holy shit!
i ran 34 psi on 204 40 17 on a 9 for the front, now run 215 40 17 on a 9 front with like 33 psi.

You ran a 204? Is that like a special size?

You're basically agreeing with me. Why start shit?

[gotta240]

there are some VERY VERY different ideas of a SAFE tire pressure on stretched tires...

Has ANYONE actually popped a tire off a rim?

[McRussellPants]

yeah once, when I ran 40 psi.


surriously 55 or bust.

[FaLKoN240]

I did, when I hit a curb.

[McRussellPants]

god I hope someone actually trys to drive with 55psi in their tires.





what?

[drift-it]

ive ran 70, while drifting.

[DemonicDonut]

stock tire pressure is 28 psi... why would you run max tire pressure? just runs the center down quick, these cars are to light to run that much pressure.

Hey donut, you might want to reconfigure your computers firewall to allow sarcasm to pass through. It was a dumb question, being answered with smart-ass answers.
