Looking to compare tire sizes before you buy? Do you know the difference between a 245 and a 265? How about a 285 and 315? Well that depends on a few things. Metric tire sizes are a bit demanding when it comes to understanding what size they really are. Those numbers are only good with the other two. A 33 is a 33 no matter what, but a 265/70/16 is a 30 1/2" tall tire and a 265/75R17 is a 32 1/2" tall tire. Use our the tire size comparison calculator to find all your tire comparison needs.
Our tire size comparison calculator takes two tire sizes and directly calculates the differences between the tires diameter, width, sidewall, circumference and revolutions per mile. Just input any two tires, metric or standard, and click the button. Then as a bonus it shows examples of your speedometer reading with the first tire, and the actual speed you're traveling if you were to install the second tire. A very useful tool when searching for tires that are a different size then stock. Enjoy this page for all your tire size comparison needs.
