Update on my Rotted Hoosiers. Pics included

I used to run M&H Racemaster slicks and had them for years setting in the garage and they never went bad. I deal with Summit alot and have been looking to order a set of rims. But now if they don't back what they sell I'll look at a different supplier.
I hope Hoosier helps you out with your tires, No tire should start decaying so quick are they using inferior materials ? Just as a side note I had a 41 dodge that I bought that had original Goodyear tires that was bought back in the early 50's which the tires still held air and were just starting to crack. So with all the advances in tires whats wrong with Hoosiers ????????? Good luck i hope they step up and takes care of the problem.
