I tried. I don't know what tires I have. I did notice that they need to be balanced or something. What? I'm not sure. I'd put up a vid but my laptop and camera don't want to get along today. It is killing me.

First remov
Sounds like your beads have come unglued and are running out of round. remove tires from rim. Put new foam inserts in tires. remount tires and re glue. Also tires, like anything else, can be modified. If you have the knobby tires and they are loading up with clay/mud, you can trim some of the knobbs so the mud releases. Once a tire loads up it is like driving on slicks. That is why most racer kits you see at the track have several different tread patterns.

WOW! I'm not sure about that. Didn't notice it in the dirt. On the street I sure did. When I get it running I'll look.
