Does anyone have any experience with the RC4WD Demolisher tires? I just discovered them, and I was pleasantly surprised that the IMEX Kong tires are not the biggest on the market . A set of tires w/ foams comes to about $140, which is pretty much on par with Jumbo/Swamp Kongs. However, the RC4WD aluminum beadlock wheels are like $200 for a set of 4. Does anyone know of plastic wheels that will work?

Also, general discussion about using big tires. Are there other tires (perhaps in the 1/5 scale realm) that fall into the 8"-10" diameter range?
