Tire size in inches and millimeters
225/60R16 tire size in inches
A 225/60R16 tire is 26.63 inches tall (676.4 mm) and 8.86 inches wide (225 mm), with a 5.31-inch sidewall (135.0 mm). In inch notation that is about 26.6x8.9R16, close to a 27-inch tire (nominal).
Its circumference is 83.66 inches (2,125.0 mm), or about 757 revolutions per mile.

Where 225/60R16 fits
- Inch class: 26.63 in is near the bottom of the 27-inch class (26.50 to 27.49 in), so some listings call it a 26-inch tire.
- Profile: the 16-inch rim plus two 5.31 in sidewalls make up the overall diameter, and the sidewalls are 40% of it. At 60 series that is a mid profile, between low-profile performance sizes and tall truck sizes.
- Same 16-inch rim: the next taller catalog size is 215/65R16 (27.00 in, +1.40%) and the next shorter is 215/60R16 (26.16 in, -1.77%).
- Same 225 mm width: the closest in diameter are 225/50R17 (25.86 in, -2.90%), 225/45R18 (25.97 in, -2.47%), 225/55R17 (26.74 in, +0.43%), 225/50R18 (26.86 in, +0.86%). At the same width, a different profile or rim changes sidewall height and overall diameter, not section width.
Reading the marking: 225 is the section width in millimeters, 60 is the sidewall height as a percentage of that width, and R16 means radial construction for a 16-inch rim. Percentages are measured from 225/60R16.

Important: These results compare nominal dimensions. They do not confirm vehicle fitment. Actual clearance varies by tire model, approved rim width, wheel construction, suspension, alignment, body tolerances, steering angle, load, and brake geometry. Verify load and speed ratings and physically test-fit the complete setup before driving.
Physical checks before changing size
- Approved rim-width range for the exact tire model
- Load index and speed rating equal to or greater than vehicle requirements
- Brake-caliper, hub, and wheel-fastener compatibility
- Fender, liner, suspension, and full-lock steering clearance
- Clearance at full compression and under expected load
- Alignment, tire pressure, and manufacturer guidance
- Professional inspection when variance or clearance is uncertain
