So I have had had toyo oc 315's (~34.9") on my rig for about 6 or 7 months now. Over the last couple of months, I have noticed the truck feeling a bit wiggly on the highway (the best way I can describe it). when traveling on the highway I find that I have to correct the steering more than it should have to be. It feels like that of a windy day. The truck sort of deflects of the straight path a bit. The wheel feels tight, no slop, but I find myself constantly adjusting the wheel to correct for slight unpredictable jogs to the left and right. It is not extreme, but it does not feel right. Another way of explaining it is: It feels almost as if you were riding on top of some smooth railroad tracks and you needed to keep the truck perfectly balanced to stay on top(probably some bad examples here, but that's the best I got). Maybe it is just out of alignment or something. any ideas?
