i was counting myself lucky as i accidently cought a circular saw blade in the belly,while building a new bed on the '57 chevy truck fortunatly, it was winding down and my overalls caught the damage, then i had to go haul a load of mulch, that started it, i noticed a inner dual tire blown out on my little dump truck, i had one, or so i thought, spent 2 hours fighting the old tire off the rim, its a 30 mile trip to town and i really didnt want to pay some kid to do what i can do myself, fought the good used tire on and went to inflate it, thats when i noticed the nice pocket knife shaped slit in the sidewall, so now i ordered 2 new tires so the dual set matches, just should have stayed in bed...
