What bullet32 said happened is also what the other Federal people said when I called and sent pictures. Federal was very professional and treated me very well. I struggle with the idea that a tyre would self destruct so badly if you got a flat and pulled off the road as soon as it became apparent, but I also have a limted experience with low profile tyres. If so, well thats life...
I would say I thought these were, especially for the money, great tyres. I'll buy another one to replace this one and keep running them on the street. Moving down the path of getting semi's for the track.
