MT's weak point

After all my praise of these tires, they finally let me down. After my tire went flat today, I discovered a split all the way around the inside, where the tread meets the sidewall. They still have a decent amount of tread, so I took it Discount to see about some kind of warrantee. They told me they have tried to have that issue warrantied before, with no luck. Guess i'll try to find another tire that hooks well and lasts a little longer.
