Can bad alignment do this to rear tires? One of my rear tires separated like that about a month ago, but it may have been caused by a partial flat. I found a piece of a scissor stuck in it afterwards :dw:
I had the same thing happen to me twice on my cobra 2 different sets of Eagle F1's I think it is the soft tire compounds we are using they just dont hold up like other compounds.
For daily driving they are pretty good. I have not gone to the track, or really tried to launch with them yet so Im not sure how they they hold up performance wise.
You already stated the biggest problem. The tires were 2 years old and they were Goodyears(good4ayear) tires. Seriously though, aligment and the semi flat is more than likely the cause, the crappy GYs is just icing on the cake.
