duro hf904: low pressure tube failure analysis

Looking further at the pattern of scuff marks on the tube RE my previous posting. I always mark the place on a new tire where the plies overlap, and position it 180 degrees from the valve stem. At 18psi, the tire torqued around on the rim, and the tube tried to follow it, gripped by the molded-in strips on the inside. After patches allowed a slow leak, a catastrophic failure occurred: pullout of the valve stem. :-( IF YOU MUST run the HF904 soft, best to drill the rim and install a rim lock (which makes changing tires a B**CH!) or install bead screws, like ice racers and hill climbers use. Do not despair, the HF904 is a thoroughly competent tire on street and dirt; my experience confirms its traction capabilities off-road! They seem to hook up better on loose surfaces if left at listed PSI. Jake

Hopefully, now that young men will be shedding their blood once again to protect our country, not the politicians in Washington, we will remember that they are not sacrificing so half of this great land can be owned by the federal government. It is a country "of the people, by the people, and for the people". Russell ----- Original Message ----- From: Tobin S.
