Yes, thirty-five-inch tires will fit on an H3 Hummer with absolutely no modifications. Even the factory spare tire mount on the tailgate will fit a 35″ tire just fine. There is however a few things I recommend when mounting a tire that big on the H3. But overall, having 35-inch tires on an H3 Hummer is worth it.Feb 28, 2013
What size tires are 285?
YES, 285 wide tires are the same as 33” tires although 285 is the tread width in millimeters and 33″ is the tire diameter. 285/75/16 is usually the accepted metric equivalent size for 33's. 16.831″ + 16″ wheel = 32.831″ approximate tire diameter.
