Default Tire Pressure Recommendation?

Does anyone know who to follow for tire pressure recommendation, Chrysler Corporation or the tire manufacturer?

I have an '06 Touring Edition. In 08/08 at 33,809 miles I had to replace the original tires due to tread separation. I purchased the Goodyear Assurance TripleTred that have an 80,000 mile warranty. Recently the vehicle began to hydroplane on wet pavement and I no longer felt safe driving, so I took the vehicle to a Goodyear retailer to have the tires inspected. They found that the tires were worn in the center of the tread and needed to be replaced, they only had 25,865 miles on them. Goodyear gave me a pro-rated credit on the tires, but I still ended up spending $372 to replace a set of tires that should have lasted me over 6 years as I drive approximately 13,000/year. I purchased the Goodyear Assurance ComforTred Touring which also have an 80,000 mile warranty.

I have always used the original stock size tire, P195/65R15. Per Chrysler, the Tire And Loading Information label on the drivers door pillar recommends 35psi, but Goodyear says to run 32psi. Who is correct? I have always maintained the tire pressure on the vehicle and have followed what the label says, 35psi. But I am concerned that the TripleTred tires wore out prematurely due to being overinflated and I don't want the same thing to happen to the new tires. So again, who do you believe, the tire experts or the vehicle manufacturer?

Tire manufacturer usually states the maximum inflation that the particular tire can handle safely, Goodyear has no idea what vehicle the tire is mounted on. You are correct to follow the Chrysler "Tire and Loading Info Label" on the door pillar. Mounted tires should have a maximum inflation rating above what the Chrysler label recommends. The tires are to be cold when checked and inflated to proper pressure.

Here is a snippet and link from real tire experts, the tire manufacturer ... not tire salesperson.

Recommended Tire Pressure

If you don’t know the proper inflation air pressure for your tires, what do you do?

Easy. Check at one of the following places on your vehicle:

* In the vehicle owners manual.
* On the vehicle’s door jamb. (Often, a vehicle information placard is located on the door jamb along with the recommended tire inflation pressure.)
* Inside the fuel hatch filler flap. (In some vehicles.)
* The glove compartment door. (In some vehicles.)
o But NOT on the tire. The inflation pressure shown on the tire sidewall is only the maximum tire inflation pressure. In most situations, the vehicle manufacturers recommended tire inflation pressure is shown on the vehicle placard. However, on some older vehicles, the recommended pressure listed by your vehicle’s manufacturer may be shown as two numbers: One for city speed driving and normal load and one for highway speeds and/or maximum capacity vehicle load. Be sure to inflate your tires to the recommended inflation pressure for each type of driving situation.

You really expect to get 78,000 miles on tires? Good luck....

No I don't expect to get the full 80,000 miles that the tire is warranted for, that would be wishful thinking and there are too many other variables involved. But I also don't think that an 80,000 mile rated tire should wear out after less than 26,000 miles. But even the Goodyear rep said that where these tires were on wear that I should have about 70,000 miles on them.

But now I'm just more confused. Goodyear has now corrected themselves and state that the 35psi as recommended by Chrysler is the correct tire pressure for my vehicle.

But the Service Manager at my local Chrysler dealership says that in some cases it may be adviseable to reduce tire pressure by 2-3 pounds to improve ride comfort.

One issue may have been that the Goodyear Assurance TripleTred tire is a directional tire, that it can only be rotated front to back on the same side of the vehicle, unless a person wanted to have them removed from the wheels, remounted and balanced to put them on the other side of the vehicle. My new tires, Goodyear Assurance ComforTred Touring are not directional and therefore a more traditional (X-pattern or forward-cross) rotation pattern can be used which should improve tire wear.

So 32psi or 35psi? I guess split the difference and hope for the best!

how about size of tire?

should we adjust to higher pressure for larger rim, such as 17" rim, or stay with the same recommended pressure by Chrysler?

They don't call them "good year" for nothing. I bought my PT last February and it had brand new Good year tires on it and I estimate I will need to replace them by the end of next summer. So I'm thinking they were good for about 20-25k.

i have to agree that i have never had much luck with goodyear
i run coopers on my Pt and i have gotten as much as 75,000 on a set of there corba on my 2000 S10
i usaly go up 1 size or to the biggest i can run and still clear the wheel well but then most of my driving is highway at 70mph (or a tad more)

I go by what the TIRE says since like already said the tire does nto know what car it ismounted on
