Calculated from the nominal size, without load or tread wear. Revolutions use nominal circumference, not a measured rolling circumference. Tyre model, inflation, load and rim width can change the real dimensions.

215 is the nominal section width in millimetres, not tread width. 65 is the sidewall height as a percentage of that width. R means radial construction, and 16 is the rim diameter in inches. The commercial marking is retained here; a passenger-car tyre with the same dimensions is not automatically a suitable replacement. For the load index, speed rating and date code that follow the size, read how to read a tyre size.

Check the tyre maker’s specification

The existing passenger-car guidance does not cover this tyre type. No estimated approval range is shown for flotation or commercial sizes. Our guide to choosing wheel width for a tyre explains how to find the approved range.

Computed candidates within ±3% of the 685.9 mm diameter, on 15-inch and 17-inch rims. Width stays within 20 mm of this tyre, using 165 to 355 mm widths in 10 mm steps and 25 to 80% profiles in 5% steps. These combinations are not a stock list or fitment approval; check availability and the exact tyre specification.

How a size change moves the speedometer and gearing is covered in plus-sizing wheels. A smaller rim must still clear the brakes. Check wheel width, offset, load and speed ratings, full steering and suspension travel, and vehicle restrictions. AWD and staggered cars may need a much tighter rolling-circumference match than this screening limit.

Use the trim, market and axle as well as the car name. Each guide links to its supporting sources and explains clearance limits.
