265/30R22 — 717.8 mm tall, and what it swaps with
265/30R22 is 265 mm wide with a 30% sidewall on a 22-inch wheel. That sidewall is 79.5 mm, so the tyre stands 717.8 mm tall and turns 443.5 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.
Frequently asked questions
Q. What is the overall diameter of 265/30R22?
717.8 mm — the 558.8 mm wheel plus the 79.5 mm sidewall at top and bottom.
Q. How many turns per kilometre does 265/30R22 make?
Its circumference is 2255 mm, so 443.5 turns.
Q. What can I swap it for?
12 sizes stay within 3% of its diameter — the closest is 235/50R19 at 717.6 mm.
Q. Why is the sidewall 79.5 mm?
Because it is 30% of the 265 mm width. The aspect ratio is a proportion of the width, not a length.
