Tire Tread/belt problems of the 1999 Ford Crown Victoria

While drivingat 70 mph tire tread separated. This has happened on several different occasions. The first time was at 38,551 miles, and the second time was at 74,904 miles. The tires were guaranteed for 70,000 miles. Pep boys, futura plus, p225/60r16, radio design #9937, 31985-2 r-1768, dot 3d x 0, 1 x bd0601, g03l, 0211801.

The car was parked when I noticed the missing pieces of tread. Upon closer examination of the tire, I noticed that the some of the tread was separated from the tire. Also some of the steel belts was showing. I droved to the nearest goodyear dealer and they indicated that there was 25% tread left and the amount to replace the tire was over $112. 00. I went to another store and purchased another brand of tire which was less expensive than the amount quoted by the goodyear dealer. I contacted the gooryear customer service and they also said that it was an expensive tire and that their policy was to prorate the tire. I am glad that I noticed this before going on a long distance trip this weekend. I have 2 concerns - 1. . I need to report the tire defect to somebody. 2. I think that similiar to the firestone situation, goodyear should at least pay for part of the tire replacement, not just prorated based on an artificially high list price. Recall .
