Thanks for all the info. The reason I have new tires is because the Kellys that were on it had so many weights on 2 of the tires that they finally agreed to give me a credit towards a set of Dunlaps well the Dunlaps were pretty good but now 5000 miles later I am back to this problem. I will take it in tomorrow and have them rotated and ballanced. The last time I was in Goodyear they blamed all the problems on my "wore out truck"

Toyota T100 best truck Toyota ever built "Its so good the frame does not rust in half"
