It is a balancing issue most likely. I have had my duratracs for about 3000 miles and they needed to be balanced 2 times already. I need to stop driving over curbs lol.

Will have them rotated and balanced again soon, since its FREE anyways.

 

I tried everything on my tires, including dynabeads, or whatever they are called, and the only thing that stopped it was "Toeing" the tires out. When I first toed them in, wobble worse, toed out until the problem stopped. Took it to a tire shop and they aligned the front end. They toed it in and the wobble was worse again. I toed it back out and the wobble is gone again. It still occasionally wobbles but not as bad. You might try adjusting the toe, just a suggestion and easy to do. There are several right ups on the forum that discuss it.

 

I will try the balance and rotation again and look in to toeing out, but can someone confirm that if my wheel was bent or out of round, the balance machine would pick that up and it simply would not balance?? Is this also true of a bad belt in the tire???

 

I had the same issue with my 17" soft 8's running BFG 32" M/T's. I had them balanced 5 times using 3 different shops and could not get rid of the vibration. Ended up taking them back to Discount Tire and getting 16" Eagle Alloy and 33" KM2's. No problems at all after the new wheels and tires.
