2017 RAM 2500 Tire Sizes

The 2017 Ram 2500 tire sizes listed here are 245/70R17, 265/70R17, 275/70R18, 285/55R20, and 285/70R17. These are tire size designations, not a statement that every size fits every truck. Use the size shown for your vehicle when selecting replacements, and confirm fitment if you are unsure.

The figures vary across the listed sizes: the first number is the tire’s width, the number after the slash is its aspect ratio, and the final number identifies the wheel diameter. The R indicates radial construction. The list includes sizes for different wheel diameters and tire proportions, but the facts do not connect a particular size to an engine, trim, or configuration.

The listed sizes alone do not identify which one came on a specific Ram 2500. Check the tire information on the door jamb or in the owner’s manual to confirm the correct size for your truck.
