I have a terrible vibration at 35mph, therefore it is hard to go over this speed. At higher speeds however it does diminish, but still vibrates a little. I got them rebalanced after 6k miles and it did not help. Or so they say they balanced them. I am only running 31 thornturds (got them for $20CAN each) on a 2001 X. It seems it is only in the front but hard to tell. When i pull the front right tire out, I can hear a little clunking. Could this just be improper torqued lugs??? Hope so. Anything else it could be. This all started 3 days ago, while out of town. On the way out it was OK. Back into the city, not OK. HELP!!!!!!

Mine does the same thing at about 60mph. I found out my tires (more than one) are what they call out of round which means they are lop sided from offroading. A good wheel tech should be able to look at your tires on the balancer and see if that is the case.

Is there a remedy for that??

mud terrain tires can be hard to balance
