Take the truck somewhere and get the alignement checked ($60 at Firestone..I think). When I bought my truck, apparently the previous owner has some huge tires/rims and put the stockers back on to sell it. They never adjusted the alignement after putting the old tires back on...and I tore up those tires fast. When I got my new Revos put on Firestone checked the alignment and it was totally off. Best $60 I spent; saved me from destroying new tires.
