Re: Tires & tubes Constant Failures
Do the tubes have holes in them, or long slashes after the blowout?
If they are slashed you probably arent getting the tire bead seated on the rim.
When I replace a tube I usually get the tire seated well then add just enough air that the tire holds it's shape then lightly bounce the wheel on the ground working my way around the entire circumference to make sure it's good and seated before inflating it all the way.
Also around here we have those darned goathead thorns they break off leaving no sign that they are there, you have to feel around the inside of the tire for the things or you'll get a flat in the same spot again.
