i know you might not be monitoring this thread anymore, but if you are, i plan on trying to engineer a set of inflatable tires using my HPI (non-beadlock) rims, HPI super mudder tires, superglue, and sports-ball needle inflation plugs. i got the idea while trying to figure out how to make my (converted 14v emaxx chassis to 16v chassis) lighter and realized the tires were probibly half the weight of the truck.

i have knolledge of technics that the real monster truck teams (I.E. Gravedigger etc.) use to make their tires lighter too like carving off exxess rubber.

i will post pictures and updates as they come along.
