I have a set of 15x8 Billet Spelialty wheels with 5.5 backspacing, 5x4.5 lug pattern and they come with center caps. They are wrapped in 275 50 15 Mickey Thompson ET streets. WHeels and tires were bought with the intentions of running them down the track but never happened and selling the car. Tires are mounted on the rims and have never even been used, just sitting in the garage air'd up. i will split the combo with wheels going for 540 and tires going for 400 plus shipping, or i will sell the combo for $850. Like i said these rims and tires have not ever been mounted, center caps are still in plastic bags. This sell is for rear wheels and tires only, set of 2! Call me for questions or for quick response text anytime 1(409)719-3632, thanks Justin
