I have read on this forum of balancing issues with specific Toy factory rims... But has anyone ever noticed an issue with the BFG AT KO tires? My truck had them when I bought it and I felt that they were way out of balance. They were worn but far from worn out, but I bought new ones anyway. Well 500 miles in and these seem to "wobble" the same way. They were put on by a reputable tire place here... is it just the tires or what? When I am cruising at 50MPH they just ride like sh*t. Any thoughts?
