14 inch and wider rims are dually and extreme off-road fitments where the tire is wider than most passenger cars run in total. This width appears most often on 24 inch, 28+ inch, 26 inch wheels, and it is sized for 335 mm and wider tires.
We list 2,403 wheels at this width. Width is what limits your tire choice: mount a tire that is too wide and the sidewall bulges, too narrow and the rim edge takes the hits. If you are between two widths, go with the one inside the tire manufacturer's recommended rim range.
