Question For The Tire Expert

[dreisenauer]

Any tire experts out there? Are cupping tires always caused by bad alignment?

 

I put new tires on my car, goodyear tripletread. Alignment was good, old tires showed no abnormal wear. Great winter traction. At 7k miles when I rotated them they seemed like they were getting noisy so I had them balanced and a wheel alignment. Now at about 18k mikes and after 2 more rotations, all 4 are cupped and they make a lot more noise. This once quiet car is louder than my pickup with all terrain's on. Dealers all say cupping isn't a warranty issue and won't take them in trade. Is the Hunter alignment rack not doing it's job? Did I get a bad set of tires?

 

Thanks in advance for the input...

In my experience, Something isn't running true

 

With that said, I've seen certain cars over the years that do wear tires faster than others, but thats in the design of the car.

what pressure are you running in the tires? what pressure does it say to run on the door jam, and what does the tire say max load psi cold is? I find it odd that your old tires did not wear funny but the new ones do.....

The Tripletread's I had on my Grand Marquis had to been run at a much higher pressure that the stock tires. The door jam said 32 psi. When I got them, the tire shop had them set at 32psi and the car felt like it was out of control going down the road. I was going to take them back, but I tried a higher tire pressure first. I ran them at 40psi (44psi max on sidewall) and they handled much better and wore fine. They had 50K miles on them when I used the car for cash for clunkers. I would try increasing the tire pressure to stop the cupping.
