15x10 with 5 1/2 will not work. First, the back spacing to too big, your wheel will be rubbing on the spring, not to mention there is no room for the tire. Then, once you get the 1 inch spacers you need the wheel will be hanging out too far, and unless you intend to raise up the car and hang the tire outside the fender this combo will not work ( on a stock car) however it would work if you tubbed the car and shortened the rearend.
