No breakage..... I have some 38.5 X 14.5 SX to run but can't seem to get them to run down the road without severe death wobble... 35's run fine but not the 38's... I know my steering and so on is set up well and maintained well, damned SX won't balance so I need to try a stabiliazer to dampen the meats.. I ran the 35's (were cheap) just to get out.. they lasted one trip @ Rausch : ) those rocks are sharp, numerous, and large.. when you smash down on the rockers, they spark : )
I just wore out a set of 36" SX..... fully out of round after 4 years (not bad : )
