229 welded the KOP chassis in a 6-wheel drive configuration with custom 4 inch wheels, and a custom 2-speed shift on the fly gearbox. We were very happy with how we designed and built our base. It got through FLR, Buckeye, the Championships, and RaChaCha Ruckus.
When it came to the wheels we just riveted the tread to the wheels. An adhesive will hold, but it is much harder to take and replace a tread if it becomes worn down. Not that rivets are much better, they can be ripped out of the tread and create problems such as getting the tread jammed between the chain and sprocket.
