It's happened to me once before when a wheel must not have been on tight enough....The hex hub strips out the actual wheel itself leaving the tire useless.

I have recently upgraded the drive-shafts which has allowed me to put tremendous amounts of power to the wheels but now the torque has stripped out a couple brand new rims!

What is the best way to go with this...and don't say less power.
Metal rims?
Beefier hubs/wheels?

I'm open for suggestions.
