Furthermore, you can always determine your tire size in inches the old school way, with an equation and good ol' math. Haha!! The metric sizing that most tires are labeled now can be broken down into inches pretty easily. For example: 265/70/17
265mm section (tread) width
70 is your aspect ratio, which is just the percentage of the width determining your sidewall height
17 is obviously your wheel diameter
265/25.4= 10.43 width in inches
10.43•.75=7.82 sidewall in inches
So, 7.82+7.82 (2 sidewalls in total)= 15.65 (round up from 15.649)
All that math tells you that your tires "should" be 32.65" tall and 10.43" wide. Just remember tolerances and wheel specs and load all factor into actual ride height so measure them and see where it's actually sitting.
