Understanding 225/65R16

The tire size 225/65R16 means the tire has a section width of 225mm, an aspect ratio of 65% (the sidewall height is 65% of the width), and fits a 16-inch rim.

Sidewall Height = 225 x 0.65 = 146.3 mm
Overall Diameter = (146.3 x 2) + (16 x 25.4) = 698.9 mm
Circumference = 698.9 x π = 2195.7 mm

With an aspect ratio of 65%, this is a standard-profile tire that balances ride comfort with handling precision. This profile range is the most common for passenger cars, crossovers, and light SUVs.

Choosing Replacement Tires

When replacing 225/65R16 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.
