What should my tire pressure be on my 02' TL-S? I have stock rims with Continential on them. The door says 32psi but I'm reading that some of you guys are setting it higher? What are the advantages of doing that? What psi do you set it at?

I'm do about 33/34 psi. Higher pressure will increase your gas milage, but your handling may go down and you'll wear the tire more in the middle. I think I saw someone posting upwards of 40psi before.

I run 38 in front and 36 in the back. This is a performance car, so I wanna feel all the bumps. 32 is too soft, and I find I spin too much in wet weather.

Um, you really ought to check the tire itself as well as consult with whomever sold and installed the tires for the best, everyday pressure. That being said, my Nittos sit at 36 psi...

:lol:




















I love the new SN "sc354"

hehehe

check the tire and see what the maximum psi is and adjust it to your driving. higher wont reduce your handeling it will improve it (to a point) im running 40 on mine. but the higher you go the rougher the ride (slightly) and it will wear a little faster. just check them every now and then and see how there doing

Well, I think there is a little confusion about tire pressure here. First the car manufacturer specify that a certain pressure is require for the car to handle in the way that it was intended. So it doesn't matter if you change the tire or put different rims, you still have to put the 32psi that's recommended and posted on the car's door. Any lower and when the tire is cold it will be dangerously low, any higher and as heat builds up you're going to have a rock for a tire (too hard).
Also, over inflated tires will cause the center of the tire to wear very fast. Under inflated tires will cause the outter edges of the tire to wear fast.
Only when you are going to the track and want a little better traction, you can lower the pressure of the tire by maybe 2 or 4psi below 32 and you will have better contact, any lower and you will create drag.
One last thing, over inflated tires create a lot of stress on the suspension.
Keep it at 32psi.

thanks guys. I checked all the pressures on the tires today and they were ALL different!! I just got them installed on Thursday!!! The tire was hot because I just drove from work but they ranged from 41.5 down to 35psi. No wonder my car wasn't going straight! I set them all to 38psi because if I remember right when it cools it drops down to 34psi. Maybe I should have taken a little more air out. I'll see how they are tomorrow morning. Thanks for the feedback!

most of this isnt true. the pressure is ste due to the tire and a comfort level. its going to change from tire to tire. the 32 psi sticker doesnt mean if you buy ZR rated 19's that it should be there on those also. yes it will wear a little faster at a higher psi but you will have improved responce, better handeling and improved milage. set the tires how ever you like 32 is a little to soft, a good meadin is around 35-38. i personally like 40 -42 with mine and i get 40+k miles out of them and they dont wear uneaven and it handles ALOT better than 32

Let's remember the whole "Exploder" Firestone episode. Ford recommended a tire pressure on the door jam which was dangerously low, reason being the Exploders unstabe nature. You see the softer the tire the less responsive it is,= less rollovers.
Ok back to tl, 32psi is great all around and with conservitive driving the tire will wear evenly and give a good balance of preformance and comfort. BUT if you drive agessively the edges of the footprint will wear faster than the middle, Im bored


I like 36 front 34 rear on my Sumi's

Just remember guys, those of you with the stock Michelins on your car have a max pressure of 35 lbs. (varified by tirerack.com) I would start playin' with the higher settings till you get those things off of there.

goldendragon576

Are these numbers your posted on a cold tire??

r10apple

Some dealers were even swapping Firestone tires for larger ones and inflating them at the door sticker pressure rather than what was recommended for the individual tire. Tire pressure has a lot to do with the Ford rollovers as did driver error which was compunded by the soft, unresponsive tire...

The bottom line truly is that ALL tires are different. Manufacturers of the tire recommend settings for pressure and I would follow that above anything...And Blasing is right, you start putting 40psi in your stock Michelins, you are destined for trouble with heavy, highspeed driving driving...

mine said 44

I wouldn't lower your pressure on the track - sidewall flex and roll over is not good for the tire or your handling on the track.

I would run higher pressure on the track to stiffen up that tire, not to stiff to loose traction though - it is a trial or error thing.

On the street - 32 to 34 psi cold is fine.

Tom Blasing

Yea, I'm not sure what was onm the side of mine so I'll have to look after work today. I would love to run these +6lbs. or so.

My last set of Goodyear RS-A's on my old Talon are still going strong with 62,000 miles on them. That's ONE set of tires . They were at 6lbs. over mfr. label. Wonderfull gas mileage (sticker said 29hwy. but I wound up getting 39-41 hwy.), wearis nice and even, steering response improved etc....I hope I can so this!!

33/34 in the front (i have plus 1) and 32 in back i hate the feeling of loosing the back end in the rain.

I think he meant the drag strip. Lower the front psi for traction and pump up the rear for less rolling resistance.

jgatortl

I see - that makes sense - for a drag strip
