What tire pressure do you run?

[aaaauroraaaa]

as the title says...


I have 2nd gen 17" wheels on my first gen and run 34psi in front and 32 in back.

[Marc]

2001 4.0.......stock 17" wheels........38 lbs. front & rear.

[aurorabrain]

17" Lucerne Midnight Silver wheels 235/55/17 at 34psi front and 32 rear.

[latenight72]

Stock 17" 2001 4.0

I have ran 25psi once, was too loud and felt like I was going to roll the bead off the rim, I have run 35psi, and right now I am at 45psi.

The 45psi is a much firmer feeling tire, but it helps keep rolling resistance down, and it is actually slightly quieter.

Factory recommended pressure (30psi) front and rear on factory 16" wheels on my 1999.

[95mushroom]

18" GXPs, on the Aurora, I kept it at 42psi. On the STS, @ 45psi.

Todd, 45psi is actual 1psi over MVX4+'s Max Inflation Pressure.

[Marc]

I know that the 235/55R-17's max pressure is 44 lbs. I'm using 38. Would there be a noticeable difference in rolling resistance between those 2 pressures?

255/50R17 BF Goodrich on 17" rims at factory recommended air pressure.

Uh..... Just Checked, their at 43/42 actually. ;D

The tires will loose 1-2lbs in the first 3-4 days, than not loose a pound for the next two weeks. Might have something to due with their age/how worn they really are.

Can't really call my 16's aftermarket, since they're chrome torque stars (factory option) from a 97-99 Bonneville. I run them at factory recommendations, between 30-32psi depending on the tire temp. I didn't see a poll option for that (stock wheels AT recc)... ?

Edit: anyone notice that shops don't seem to pay any attention to the doorjamb reccomendations? Every time I have my tires rotated or oil changed, they come back at 35 psi all around.

[algonquin]

I run stock wheels and Yokohama Avid V4s on my 95. 34 psi front, 32 rear.

BINGO!!! I thought I was the only one who found these MORONS around the country. I have lost track of how many times I've had vehicles services and I specifically tell the service manager to put in XX tire pressure by the door decal. After the service I ask or check the pressure myself and I find 35PSI in the tires. When I go to the service manager I'm told the tire recommended pressure is on the side of the tire. When I point out to them the factory decal with the factory recommended pressure they plead ignorance and go by what the tire says. I get pissed and say "FINE" if you are that ignorant I will not come back here.

What does the doorjamb say the pressure should be for stock 17" 2nd gen wheels?

30psi.

I usually run 32-33psi front and 31 rear. Basically just a little buffer on top of the factory recommendation. I doubt I could tell the diff if someone came around and let them out to 30psi.

[Rocketv8]

factory 16" wheels and i run a bit over manufacturers recommended psi, about 32-34 lbs because i think it rides better with a little more pressure

[JimW]

Just be aware for those running higher then recommended PSI, in the summer air expands due to heat. Its probably neglibile, but still something to be aware of. Those running 32 are fine, I'd get worrid personally at 34-35psi.

[human]

I generally run my stockers at about 36 lbs.

calm down, first off nobody is ignorant....... i want you to air tires all day and see if you dont develop some happy medium. darn you act like 35 psi is the end of the world. lord forbid they forget your oil change sticker. you act like the freaking tires are going to explode off the rim. as a master tech anything between 32-36 psi is fine for a customers car.

i run 36 psi in my classic, and 46 psi in my neon's low profile fuzion zri's.

there are more important things to worry about when you get your car serviced than exact air pressures, really.

Wow... So if you do the same job every day, then it's ok to take shortcuts and cut corners?
