Ya I should have few of those extra thicker RPM hexes.
I am a tire FIEND! I love tires..so dont worry I already have a few sets planned out lol. I will have some road hawg I buggy tires for high speed runs/street play, and then all the buggy/truggy tires for offroad as well as a few sets of 2.2 for onroad/offroad and track.
I think I have more fun buying/changing tires on my RC's than driving them :)
