There seems to be quite a few questions on converting metric tire sizes to inches. Does anyone know the formula?
What is a 255 / 65 /16 in inches?IP: Logged |

One inch = 25.4mm The first number is the width of the tire in mm. The second number is the sidewall height as a fraction of the width (i.e. 0.65 x 255 = 165.75mm). The tires total sidewall height is then 2 x 165.75 = 331.5mm. This is 13.1 inches. Add this to the 16 inch rim diameter and you get 29.1 inches as the overall diameter of the mounted tire.

Jeff, you must be a pro, bulls eye. For you
Rock, if you need to calculate the diameter,
you are probably looking for a replacement
size. You are for sure driving either a
Mercedez ML320, 2000 Nissan Pathfinder SE or
an Infinity QX4. Replacement size is for those vehicules 235/70R16.IP: Logged |
