these will meet your size goal, or are very very close to it. i hear these do great offroad for jumping but are gargbage for on road. what size of hex are you looking for?
Actually they do pretty good on pavement as long as they aren't wet from rain water or dew but they shed moisture pretty quick plus they don't ballon as bad as most tires do.
thats what I have on my savage 4.6 now. I have one screwed up rim & i haven't been able to find anyplace that has these tires rims. Everywhere is backordered or out of stock. I got this truck used but like the tires on it. I'm ordering a new 5.9 but didnt want to keep the stock tires on it. As far as the mounting goes it wouldn't be a problem for me to mount them its just would rather have them mounted just because it seems like its cheaper that way.
