Cpcs:I1410421A. 2005 Toyota Prius. Consumer stated the car was taken in for a wheel alignment. Apparently, Toyota has not allowed any way to adjust the rear toe or camber on the Prius, which can result in steering issues and problems associated with excessive or uneven tire wear.

I recently had a Michelin tire separate on the rear of my 05 Toyota Prius. Tire ware has been a continual problem. I discarded the original tires at 40K miles, they were too cupped to rotate and too dangerous to use. There was a lot of tread left on the tire, at least half, but cupping gave intolerable vibration. I had Michelin tires installed and had the alignment checked. The alignment was not perfect but was within spec. The Michelin separated about 40K miles later and was replaced before it failed. The tread separation caused a total loss of tread in one line at a diagonal across the tire tread. Luckily I had gone in for rotation when they discovered the problem. The extreme tire ware causes noise and vibration. I have been in touch with the dealership throughout my ownership of the Prius which I bough new. I have requested technical bulletins but none have ever been available. The dealer has never acknowledged that the Prius has a problem but it has been documented in online computer sites. The dealer just keeps suggesting that I rotate the tires more frequently. With my past cars I have never had a cupping problem even with rotation and with the Prius since it is within alignment spec, it should not wear tires like it does. Anyone who does not rotate and change tires frequently on the Prius is looking for a blowout.

My 2005 Prius had a flat tire last week, I took it to a tire shop to find out all four tires were worn due to alignment problems with the car. I have had it serviced each time at the dealer where I purchased the car and they rotated the tires once, I thought they had twice. In any event they said I must have hit a large pothole with my rear tire, because it was the worst. All four tires had worn unevenly. The original tire dealer I took the car to said this was a common problem with the car and the second tire dealer where I had the alignment done and new tires put on said it was a common problem. They have developed a shim for rear wheel alignment and said it was a very common problem with the Prius. They also said they could see no evidence of and damage by a pothole or anything else. I felt bad the dealer would not own up to the problem. I know I didn't rotate tires as often as I should have, but I have a Mercury and Ford that have their tires rotated about ever 15,000 miles. I get great tire wear and have had no problems. By time I got the alignment and the tires I was into it over $500.(that's a lot of gas). The tire dealers said it was the car more than the tires. I have had Toyota in the past and was very dissapointed in their response to this one. I have sort of lost confidence in this car and even discussed getting a different car with the dealer but they were unwilling to discuss that.
