i need one to make a set, have one with a cut in the tread that i can't seal up by pluging or patching, if anyone knows what works in these for a tube i'll try that also, it's on a alum wag spoke rim, but have steelies to switch it to if i need to for a tube to work. as far as a tire if possible i'd like to match the 33x12.50 widetrack radial baja xt, but anything that holds air and has legal tread will work.
