helps a little bit, im wondering if the new tires im going to be getting that are 17x9 are going to fit that. I guess im confused on the difference bt the 70/75285/75/17 is approximately 11.22" wide x 33.83" tall. The 285/70/17 is going to measure 11.22" wide x 32.708" tall. The tires that you are getting are going to be 1.122" smaller (height). Hope this helps...
yes. What he said. To take what he said perhaps one step further, the 285 as he said is millimeters. The 70 or 75 is the the percentage of the width. When converted to english units you multiply that times two. That being the top and bottom and then add the rim diameter.The 70 and 75 in the two tires are the ratio of the width of the tire to its height. In other words 70% as tall as it is wide, and 75% as tall as it is wide. The first number (285) is millimeters. Convert that number to inches to get the width of the tread. Then the 70 is the percent of the width that the tire is high (from mounting point on the wheel to the tread, not the overall diameter of the outside of the tire).
So, the 285 is 11.22 inches wide, and 75% of that is 8.4 inches from mounting point on rim to the "top" of the tire. And it mounts on a 17 inch rim.
i went on their website and found where they show the inches of each tire and show which rims they could fit. really helped meNitto's site has some video's to explain the tire marking, size etc.
They actually aren't too bad.
