Yeah, I googled it and no one that carries Imex has any 2.8" stuff in stock. The road runners are ideal for me since I'm running strictly on-road (parking lots and such).
Well, just ordered the road runners and the white dishes. I also noticed that the 2.2" tires had a smaller diameter which means I'd have to gear up to 24T pinion to keep about the same speed. 22T 32p 1/8" bore pinion was hard enough to find!
