My tires have seen better days. The Boss, my wife, promises new tires this year (39.5 Iroks), but until then I'll keep trucking along with these. I'm dropping them off tomorrow to see if they can be vulcanized. I ran them hard last weekend, but they just kept on rolling.
Post up your sidewall toughness and story of how far you pushed them until total failure.
I tried filling the splits with vulcanizing glue. It sealed them, but not much else. Surprisingly, they don't leak.
