Reading the 235/50R17 size
- 235 — section width in millimetres (9.25 in).
- 50 — aspect ratio: the sidewall is 50 % of the width, 117.5 mm.
- R — radial construction (ZR on the sidewall means a high-speed rated radial; the dimensions are the same).
- 17 — fits a 17-inch diameter wheel.
The load index and speed rating (for example 91V) follow the size on the sidewall. They must meet at least the values on your vehicle's tire placard.
