Tire Bubble problems of the 2000 BMW 528

New tires eagle f1 asymmetric bought and installed in may 2011 ( unknowingly rec'd 2007 production tires ) and then removed my tires for winter tires in November 2011. When reinstalling the summer tires this spring / April 2012, multiple bubbles were apparent on 3 of the tires and the 4th tire had a bubble as well. Was told by an independent goodyear tire vendor that the bubbles resembled the effects impact damage. Furious and puzzled as to how these bubbles appeared after having sat a winter indoors and no damage was apparent when the tires were removed ( on rims ) at season's end. The tires were dismounted and remounted this spring. The bubbles emerged after reinflating them. How could there be multiple impact bubbles in different spots ( all on outside ) on the same tire and all tires have these bubbles? goodyear is trying to avoid responsibility and only willing to give a percentage as goodwill ! this is the first time I have ever had an issue other than early tire wear let alone all four tires with multiple bubbles on 3 of the 4 tires ! being shipped tires that were 4 years old could not have helped this situation. Very frustrated by the whole drawn out handling and processing by goodyear. They are denying fault which will be fought and proven to them at their expense.

A bubble in the rear passenger tire caused a blow out. Consumer pulled over and changed the tire. Dealership was notified, but did not resolve the problem. Pirelli p245/451794.
