Tire Size Breakdown
The breakdown of the tire size 315/70R17 is as follows:

  • 315: The first number, 315, represents the width of the tire in millimeters. In this case, the tire has a width of 315 mm or approximately 12.4 inches. This measurement refers to the distance between the outer edges of the tire’s tread.
  • 70: The second number, 70, indicates the aspect ratio or profile of the tire. It is the ratio of the tire’s sidewall height to its width. In this case, the sidewall height is 70% of the tire’s width.
  • R: The letter “R” denotes the tire’s construction type, which stands for radial. Radial construction is the most common type of tire construction, where the tire’s plies run radially across the tire from bead to bead, providing improved performance and durability.
  • 17: The final number, 17, represents the diameter of the wheel rim in inches that the tire is designed to fit. In this case, the tire is compatible with a 17-inch wheel diameter.

So, tire size 315/70R17 indicates a tire with a width of 315 mm, a sidewall height that is 70% of the width, radial construction, and is designed to fit a 17-inch wheel rim diameter.

Replacement Tire Size
Opting for replacement tires that maintain an overall diameter within 3% of the original 315/70R17 tire is recommended.

Tire Size Overall Diameter Difference
305/70R17 33.9″ (860 mm) -1.6%
285/75R17 33.9″ (860 mm) -1.6%
275/80R17 34.3″ (872 mm) -0.2%
