I purchased the Rims from BA Bolt (not sure if he is still around but he put out top notch work) The width was increased on the rims by 1 3/4'' to accomodate the tires.

The truck looked great with the wide rubber on the back

A great choice for someone not wanting the extra weight of 20's or just wanting to improve the looks of their Lightning without spending a ton.
