Dude.. seriously, give it a break. we WANT the tires to heat up. They grip when they're hot. (insert video of Greg boiling the hides then popping right over a rock)
P.S. Tires normally come apart from the outside, not the inside.
P.P.S. That whole firestone crap was because of ignorant-ass drivers that don't check the pressure, and cheap tires that can't handle a vehicle that's within spitting distance of max GVW when 2 people are aboard.
P.P.P.S. You'd probably shit a brick if you saw the liquid cocktail that's inside my tires.
