i already stripped out a hex on my new tires
they are only 14mm, so i put a little jb weld between the hex piece and the wheel hex and i didn't use enough. maybe i can get some thick CA and cut a few slots in the wheel hex and glue the hex piece in place.
edit: also, i snapped a HPI super duty front driveshaft today as well. the tires weigh a TON and the truck must weigh at least 16lbs. nose wheelies from braking hard really takes a toll on the front drivetrain.
