Re: High Speed Rear Blowouts
so, uh, back on target here, there's some stuff called "rim cement" that's designed for tubular bike tires which might work. you could try it on the beads of your tires, maybe that'll help.
i wouldn't drill the rim out and put in a grommet. i think the air pressure, rider's stress, etc. might just blow it out. and it'd probably weaken your rim.
