Just a heads up guys, often times tire pressure is something thats overlooked. Spending 4 dollars for a pressure gauge is the best 4 bucks you can spend (Except for Artic Silver :D ) I always run mine either at 5 below max or 45 PSI, whichever is HIGHER. A firm tire gives better perforamnce in corners, is safer, and gives better gas milage.
just lookin out for all my ATOT fella's! :)

Anandtech PSA....


Good advice though. Mine run at 30PSI. Stupid 12" tires.

I've been hit by lack of tire upkeep. While I was moving. In the middle of nowhere, MS. At 3pm. When it was 101°. That sucked.

shockwave, you are probably overinflating your tires with that much pressure.
you will have uneven tire wear.

45 PSI ??? Are you driving SUV/Truck ? I can't imagine going more than 40 PSI for regular 15-16' tires on car. Most recommendation fall around 30-32 PSI.

Yep, the tire will have a tendency to wear out the center of the tread first. However, there will be less rolling resistance, so your gas mileage will increase a bit, and acceleration will improve slightly (especially if the tire was previously underinflated)..

negative. Recommended is 35-50
But, with a 2.5 ton vehicle, I can run a bit high :D

In a car, that is a bit high, but I love the extra grip i get through corners. My car (A Taurus, ohhh sporty) needs all the help it can get, and the difference between 25 PSI, and the 40 i run at is AMAZING.
But ya, for a car that is a bit high i guess. :D

I you buy a tire gauge (& you should) even a cheap digital is much better than using the one @ the gas station. Should be able to pick one up for $10.

Well, regardless of what everyone likes to run, be it below for a smooth ride, above for performance, or dead on, I just wanted to remind everyone to check it. Like I said, its something we rarely think about. Anywho, I'm off to CS to kill someone. Will it be you? ;)

I have to disagree with you there. Alway run the TIRE manufacturers recommended pressure on the side of the tire. It can Vary greatly from what the door says (see explorer)

I guess these drag radials should be inflated up to 40 or 50 PSI then for better grip, right? Damn, and I was running them at 15psi, I must be an idiot....

If you do a lot of high speed highway driving, especially in the summer and across deserts, you are best to keep your pressures at or a little below the mfg. suggested rating. The heat from prolonged driving in high temperatures will heat up and expand the air in the tires and if they are already overinflated this could cause a blowout. Happened to me twice on vacation last year in New Mexico.

Most would end up looking like donuts at around that pressure. :D

Except that underinflating them cause more rolling friction, which generates more heat, and gets you back to the exact same place.
