drag radials

Well putting "best traction" and "drag radial" in the same sentence is the 1st problem... What kind of power are you making? Is the truck lowered or lifted? What size wheels are on it now? There are a lot of variables involved. Drag radials are low profile "sports car" style tires so just go with whatever is the widest you'd like. If you can get a 15" wheel on then Hoosier makes a 295/65/15 that would work well. The Nittos and BFGs are pretty similar and can work in just about any wheel combo you'd choose.
