WRONG!!!!!!!!!!!!!

ALWAYS GO BY VEHICLE MANUFACTURER RECOMMENDATIONS!!!!!!!!!! the number on the tire is a MAXIMUM based on the strength of the tire, and has NOTHING to do with how much you should inflate


ALWAYS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Cheetah, I would lower that pressure to safer value asap. Is that warm pressure after driving? I hope so. The tire pressure can increase as much as 6 psi after being heated up by driving.
IMO, for how cool it is up here, (hasen't hit over 80 this summer and it snowed 8 may) I should be fine. However, when I get to OR, then I'll let some air out

you do realize that by overinflating your tires, all that you are acchieving is a SLIGHT increase in fuel milage, but a large decrese in handling abvility, tread life and suspension life

I see I have opened a can of worms. Mileage and Possible acclerated tire wear; yes I agree with you. Handling and suspension life, I see what your saying, but I have not noticed a big enough loss to worry about it.

Back to the buying part, I bought my last tires at http://www.discounttire.com

I like the way you can go to their website, plug in your vehicle, and it will show you the recommended tires, any upgrades that will fit your wheels, who has them in stock in your area, as well as ordering them right there and making an appointment to get them installed.

Cheetah - 45 sounds way too high. How'* traction in the rain? I would also expect the middle of the tread to wear out early. You must get great mpg'*.


nd123416 - The tires on my wife'* van were losing about 20 psi a week. We went to Dunn Tire in Niagara Falls for new tires & made them aware of the leaking. They used a grinder to clean all the corrosion off the alloy wheels. The tires have been on for about 6 months & haven't lost a pound of pressure. You probably know that Dunn gives you the Nitrogen with a new tire purchase.

Th traction in the rain does not change with new or used (unless it'* bald - search Bonnie vs. Fence for pics). The tires are rotated often enough and if the tire is rater for 44 psi, it won't or should not create a bald center.

You'd use the max pressure when the tires are near the max weight limit. The weight limit is probably around 1500 lbs/tire. If your car & cargo/passengers weighs 6,000 lbs then you'd want to use max pressure. It sounds like we're not going to convince you to drop the pressure. Call any tire dealer & ask them what pressure to run. I'll bet if you call ten that none will tell you to use the max.

If your cargo and passengers weigh 6000 pounds youre probably pretty close to overloading the vehicle if you havent already. The GVWR is usually in the 4ks or low 5ks, so putting 6000 lbs on the car is probably not recommended anyway.

I will continue to run about 45 psi in my tires, If i ran 30 I honestly think my front sidewalls would be rubbing on corners, because theyre pretty pooched out already, but I know thats just the nature of radial tires.
