mt tires for high speed?

[tashpop]

i'm looking for something that'll stay somewhat together for high speed passes. right now i have some pinned tires that are taped that still flap and come unglued and unbalanced at high speeds, and a set of road rages that stretch and come unglued at high speeds. basically, i can't seem to keep them glued. i really don't like taping them up. i found that the side walls still stretch and i get a l-l shaped tire with it taped. also this really seems to upset my truck. i prefer to let the tire still stretch some so it keeps round and a better contact patch. plus it helps keep contact if one tire lifts by expanding that tire due to unloading on it.

a couple of thoughts i've had are to search for maybe a denser foam,harder tires, going to 40 series for the shorter sidewalls, or maybe looking at the narrower truggy tires like the proline mtr's. another thought was going with some beadlocks, but i've never messed with them and i've heard they add alot of weight. if anybody has battled with this(im sure several here have), please let me know what you've found and what seems to help. the lhs suggested i do a web search for some monster truck foam tires. that would be nice i guess, but i would like something i can also go off road with too.
