Just to clarify how tires are measured, Since there seems to be some confusion.
The first number is the width in MM. I divide by 25.3 or 25.4 to get inches.
The middle number is a percentage of the width so you can multiply the width times the percentage to get the profile height. Then You can double the profile and add the rim size to get the overall height.
Example 335 mm = 13.24 inches
13.24 inches x .30 section percentage = 3.97 profile height
3.97 + 3.97 + 20 = 27.94 total height.
Usually in a 245/255 5 percentage point on the cross section equal a 1" jump in rim size. But on smaller and bigger tires that percentage is more drastic... Obviously.
