Overall diameter 561.2 mm
165/70R13 — 561.2 mm tall, and what it swaps with
165/70R13 is 165 mm wide with a 70% sidewall on a 13-inch wheel. That sidewall is 115.5 mm, so the tyre stands 561.2 mm tall and turns 567.2 times per kilometre.

Sizes you can swap to
Only sizes whose overall diameter stays within 3% are listed. A different diameter covers a different distance per turn, and that gap becomes speedometer error.

How the code reads
The 205 is millimetres, the 55 is a percentage of that width, and only the 16 is inches. The R stands for radial construction.
How to read this
- The first three digits are the width in mm, the middle two are the aspect ratio in percent, the last two the wheel in inches.
- Sidewall height = width × aspect ÷ 100. For 205/55 that is 112.75 mm.
- Overall diameter = wheel diameter + twice the sidewall. A 16-inch wheel is 406.4 mm.
- Once the diameter shifts by more than 3%, the speedometer and odometer drift by the same amount.
