this is tricky, cause the offset on the stock wheels is hard to match with 2.2 wheels.

Offset means that the place on the wheel where the hex sits. On the tornado, this is toward the chassis.

I used traxxas rustler 2.2 rear tires on mine. They worked perfect for the rear of the buggy, but on the front the wheels inside "ribs" rubbed against the suspension arm. I had to trim these ribs with a hobby knife.

I think I read that someone used traxxas 2.8 rear tallon wheels/tires and they fit without modification.
