Understanding 215/70R17

The tire size 215/70R17 means the tire has a section width of 215mm, an aspect ratio of 70% (the sidewall height is 70% of the width), and fits a 17-inch rim.

Sidewall Height = 215 x 0.7 = 150.5 mm
Overall Diameter = (150.5 x 2) + (17 x 25.4) = 732.8 mm
Circumference = 732.8 x π = 2302.2 mm

With an aspect ratio of 70%, this is a high-profile tire with a tall sidewall. High-profile tires provide a cushioned ride, better absorption of road imperfections, and greater resistance to sidewall damage — ideal for trucks, SUVs, and off-road use.

Choosing Replacement Tires

When replacing 215/70R17 tires, verify the size matches your vehicle's tire placard (typically found on the driver's door jamb or in the owner's manual). The NHTSA Tire Ratings Search tool lets you look up manufacturer load and speed ratings for specific tires.

Key factors beyond size: load index (must meet or exceed the vehicle's requirement), speed rating (must match or exceed the original specification), and seasonal type (all-season, summer, or winter) based on your driving conditions. The U.S. Tire Manufacturers Association recommends replacing all four tires at once, or at minimum in pairs on the same axle.
