These wheels actually have an inner beadlock "ring" that's scaled exactly from a 1:1 truck, 40 bolt heads. There are also 12 simulated bolts around the center for the planetery flange. Aside from the fact that a true monster truck wheel doesn't really grab people's attention, the high offset those wheels have would put extra stress on axle components.
As Chad said, the Clod/TXT (and older USA-1) tires ARE 1:10th scale tires, where the Maxx tires are slightly shorter and narrower. It's really the bodies that are small, making those tires seem too large. Going with a Maxx tire also opens you up to the MANY different aftermarket tires available already.
