Common questions
- What is the overall diameter of a 225/50R17 tire?
- A 225/50R17 tire is about 25.86″ (657 mm) in overall diameter, with a sidewall height of 112.5 mm and a circumference of 81.24″.
- How many revolutions per mile does a 225/50R17 tire turn?
- A 225/50R17 turns roughly 780 revolutions per mile (485 per kilometre). This is the number that determines speedometer and odometer accuracy when you change tire size.
- What do the numbers in 225/50R17 mean?
- 225 is the tread width in millimetres, 50 is the aspect ratio — the sidewall height as a percentage of the tread width — and 17 is the wheel diameter in inches. So the sidewall is 225 × 50% = 112.5 mm tall.
