| Description of the problem | The original equipment tires wore uneven (cupping) producing a loud sound as speed increased. These tires were replaced with new toyo proxes tires, which eventually wore the rear tires in the same manner producing unacceptable tire noise. The current (third set) of new tires, hankook 727's, have apx. 20k miles and have started to wear the rear tires in the same (cupping) pattern. The dealer was made aware of this years ago during a maintenance visit. He suggested replacing the tires and rotating them every 5k miles. This suggestion is not a satisfactory fix. Outside of this problem the car is perfect. However, replacing tires before they're worn out is too expensive. Tire replacement off-sets the fuel efficiency rating that prompted the purchase of this car! Not one of the 3 sets of tires on this car got close to the manufacturers mileage rating! A new set of tires mounted and balanced is more than $1,000. 00. Given the cost of tires, this car is more expensive to operate than my other car, a v8 performance sedan which averages 19mpg. I'm not happy with the tire wear situation and i'm considering a replacement vehicle due to this problem. There was a re-call to replace the rear lower control arms which didn't help with this problem. |
