What is the size of R16 tires?

[MackenzieFitz]

In automotive tire specifications, R16 indicates a rim diameter of 16 inches. Most tire model markings appear as: 215/70R15. The meanings of these numbers are as follows: 215 represents the tire section width in millimeters, typically ranging between 145–285mm in 10mm increments; 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, with 70 representing 70%. Generally, tire aspect ratios range between 30%–80%. Under normal circumstances, standard passenger cars should not use tires with an aspect ratio > 75%, while luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio < 60%; R stands for Radial, indicating the tire has a radial structure, and 15 is the outer diameter of the rim in inches. If a tire is marked as: 6.00–12, this indicates it is not a radial tire but a bias-ply tire. Such tires are rarely seen in passenger cars today due to their inferior safety, load capacity, and high-speed stability, and are only used in some low-end off-road vehicles and heavy-duty trucks.
