About 285/75-17 Tires
Big wheels, big tires, and big fun: When you want to grapple on the grit, or battle in the bog, you need some high-quality mud tires that can take the strain and keep you rolling. Every tire has a code on the sidewall that provides all the vital information you need to make a purchase, and taking a few moments to learn this code makes it clear whether those all-terrain 285/75-17 tires you found are right for your rig. The first number is the width in millimeters, the second is the height of the sidewall represented as a percentage of the width, and the third is the internal diameter. That means 285/75-17 tires are 17-inch tires that are 285 mm wide with sidewalls that are 75 percent of the width. At the beginning of the code, there may be a "P" designating a passenger tire, or an "LT" designating a light truck tire. Truck tires are often large with high sidewalls for better off-roading capabilities. An "R" in the middle of the code means the tires have a radial construction, which is standard for most tires. A number after the diameter is the load index, indicating the maximum load for the tires, and a letter at the very end is the speed rating, ranging from "A" to "Y." Once you know these factors, shopping for tires among the vast inventory on eBay is easy.
