2018 Nissan Altima Tire Sizes

The 2018 Nissan Altima is listed with tire sizes 215/55R17, 215/60R16, and 235/45R18. These are the sizes associated with the vehicle for this model year; the listed facts do not specify which trim or engine uses each size.

To read a size, the number before the R gives tire width in millimeters, the next number is the sidewall height as a percentage of width, and the final number is the wheel diameter in inches. The sizes differ in width, sidewall proportion, and wheel diameter, so match the listed size to the tire and wheel fitted to your Altima.

Equipment can vary by year, trim, or engine, and the facts do not assign these sizes to a particular configuration. If you need the correct size for your vehicle or a figure not listed here, confirm it on the door jamb or in the owner's manual.
