When I bought the truck, it had a terrible set of bias ply tires on it. So the first task was to get some decent radials on it. Not having the $500 for a set of new tires, I spent a few days tracking down a used set and having them mounted.
Once they were dry I bolted them on. It is amazing how much of a difference they made to the look of the truck. Just compare the picture below to the one at the top of this article. The only change is the wheels.
