I've done more research into tires and wheels than I thought imaginable. Just when I had my kit picked out (26x9x14 Bighorns all around on STI HD6 wheels), I find that the load rating is only 400lbs on these tires. That seems really really low. I'm now unsure about buying them. I want to keep the weight as low as possible and wanted a 26" or 27" tire. Any help is appreciated.
