What 205/60R16 means

205 is the section width in millimetres (8.1 in). 60 is the aspect ratio: the sidewall is 60% as tall as the tire is wide, which works out to 123.0 mm or 4.8 in. R16 is a radial tire for a 16-inch wheel.

Overall diameter is the wheel plus two sidewalls: 16 + 2 × 4.84 = 25.7 inches. These are the nominal dimensions every maker builds to; a real 205/60R16 can measure a few tenths of an inch differently by model and inflation.

Frequently Asked Questions

A 205/60R16 tire is 25.7 inches (652 mm) tall overall. That is the 16-inch wheel plus two sidewalls of 4.8 inches each (60% of the 205 mm section width). Expect a real tire to measure within a few tenths of an inch of this, depending on the model and inflation.

The section width is 205 mm, or 8.1 inches, measured sidewall to sidewall on the recommended rim width. The tread itself is narrower than that. In flotation sizing, 205/60R16 is roughly a 25.7x8.1R16.

245/45R17 is the closest common size, at -0.0% overall diameter (25.7 in against 25.7 in). Most makers treat about 3% as the limit for a swap without speedometer or clearance problems, but always confirm load index, speed rating and wheel width before changing size.

About 785 revolutions per mile (488 per kilometre), from its 25.7-inch rolling diameter. Real-world figures run slightly higher because a loaded tire squats. This number is what your speedometer and odometer are calibrated against.
