Question: what is the height difference between a 215 and 225 tire?
Answer: 2 Answers. 215 is the tire tread width so a 225 is slightly wider. 60 tells you the sidewall height is 60% of the tread width and 15 is the rim diameter. So, a 215/60/15 is the same rim size as a 225/65/15 and slightly narrower and shorter than the 225/65/15.
