after reading the Ultimate Adventure article and just hearing general consensus on the krawlers, it's not that the tires are too heavy but more so that they get wwwaaaaayyyyyy too much traction and the resulting stress that has on the axle is too much for a lot of axles to bear. they cost a bloody fortune, but look awesome and will grab onto anything, though unless you're going to put them on your trailer queen with D60s f/r, I wouldn't buy them. Also depends on where you're going to be wheeling. Why not just do some Iroks or other Swapmer. Also I've heard about the Maxxis Creepy Crawler but haven't seen them on any rigs. That tire looks just as beefy if not more than the BFG krawler and prob will cost less.
