The traxxas brand electric fronts work, but it makes it pretty wide. I like the rpm wide wheelbase crawler rims with 2.2 truck tires. Yes the tires will tend to balloon under high speeds, but the rims don't rub on any parts.

I have thought about using the 2.2x3.0 slash based front rims with either proline short course bowties, calibers or j-concepts goosebumps.
