Since I put my tires on my truck 325/60/18, i get a slight wobble when I get up to speed. It only happens sometimes which makes me think it may be the roads, but it seems like there may be another problem. I've searched here about steering stabilizers, but didn't get much info, I was wondering if anyone had any input as to what could be the problem. Thanks.

 

More than likely it's a balancing problem, or a defective tire.
