Thanks, I've got a set of stock tires I can try. Like I said, the vibration is MINOR but I tend to be anal.

I ordered a set of cognito UCA last night but thinking I should cancel the order.

However, it should make the truck ride better. (it's not bad now, I can hardly tell any difference) but I'm more interested in ride quality as far as when the suspension loads and unloads as you go over wavy roads.
