The right wheel-and-tire combo will make or break the look of your truck. The right stance will do the same. It will also make the driving experience a whole lot better when your tires are not rubbing your truck's sheetmetal over rough sections of road. There's nothing worse than cutting the sidewall on an expensive tire because your wheels have the wrong backspacing and the tire won't tuck into the fender correctly as the suspension compresses.Getting your wheel fitment right has never been easier thanks to WheelWork's Tire Mount Mate. This incredible tool will allow you to simulate your new wheels on your truck before you order them. The tool makes determining the right backspacing, rim width, tire size, and amount of suspension drop simple and easy. A few hours spent with this tool in hand will ensure that you get your wheel and tire fitment right the first time, saving money, time, and hassle. Here's how it works.

Currently, our truck is rollin' on 15x8 GM Rally wheels with 255/60R15 BF Goodrich Radial T/A tires up front and 275/60R15 tires out back on 15x10 wheels. Our goal is to stuff 17x9 Vintage Wheelworks V48s and 275/50ZR17 Nitto NT450 tires on all four corners for a road racing-inspired look. Before we can order the wheels, we need to know if the tires will fit under the fenders and how much backspacing the wheels will need.
