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 285/25R22?
701.3 mm — the 558.8 mm wheel plus the 71.25 mm sidewall at top and bottom.
Q. How many turns per kilometre does 285/25R22 make?
Its circumference is 2203.2 mm, so 453.9 turns.
Q. What can I swap it for?
12 sizes stay within 3% of its diameter — the closest is 225/60R17 at 701.8 mm.
Q. Why is the sidewall 71.25 mm?
Because it is 25% of the 285 mm width. The aspect ratio is a proportion of the width, not a length.
