I purchased 4 new 70,000 mile general altimax rt tires in February 2013 from walmart #3581. The tires now have exactly 10,774 miles on them. They are making loud thumping noises that I describe as a helicopter sound. The sound varies depending on vehicle speed, but it seems most noticeable around 35-50 miles per hour. Steering is difficult, and the car feels unstable. 70K tires should last longer than 10,774 miles on passenger car. These tires are defective and dangerous.

In 2006 I purchased 4 new cooper lifeliner touring sle tires from a local dealer for a 2002 Chevrolet Malibu. Tires were highly recommended and touted as being top of the line. Just after a few years of service, I had to frequently add air to the tires. This was especially worse under the weight of the front axle. Instead of checking air pressure once a month, I had to check about every 2 weeks. Causes the car to handle poorly on the road, steer harder, and fuel efficiency goes down. Returned to place of purchase, and tires were removed and reinstalled to reseal. Tires were always well maintained, rotated, cleaned, garaged, and properly aired to the specs of the vehicle. I even avoid pot holes. Shop owner commented how nice they were wearing. After only about 35K miles of service and 5/32 tread remaining I returned to the shop for 2nd or 3rd time again with same complaint of having to add air too frequently. Tires were again removed and shop owner stated the tire needed replaced due to a split on the inside and potential for complete tire failure. Shop owner stated that the tires are not warranted due to age. Tires gave no indication of imminent failure. Tires are not dry rotted, no noise, no repairs, no vibration and plenty of tread depth with at least 5/32 remaining. Tires conveniently just made it past the warranty. The shop had to install my temporary spare so I could get home. I found it a bit unusual that the shop owner wanted to keep the bad tire without charging me disposal fee. I still have the tires, and curiously all 4 have hair line splits on the insides. You can't see any indication on the outside of the tire. It has to be removed from the rim to see the problem areas. Not including my experiences, I know of at least 3 other instances of cooper lifeliner touring tires having air pressure issues. I consider this premature failure and potential for accidents.

Chevrolet Malibu 2002, tires worn at 9,000 miles. The dealer replaced the tires with no questions asked. At 29000 mile the tires were badly worn again. This time the dealer refused to replace the tires indicating that the wear was the consumer's fault. The vehicle was taken to a tire dealer who informed the consumer that the tires were imperfect.

The rotors on this vehicle warped within the first year and continue to warp every two to four months. This is causing wear on the brakes which had to be replaced at 21338 miles at my cost and again at 31474 miles at the dealers cost.

The car jerks at 70 mph, dealer could not find the problem. The cruise control was stuck in the on position when starting the car (was not activated), dealer could not find the problem. The car feels unstable and shacks at 50+ mph (since the time of purchase the tire pressure has not been adjusted), the dealer said the tire was over inflated, tire pressure was corrected, but the shacking has become worse.
