LT265/60R18 — what does it mean?
- LT means "light truck"
- 265 stands for tread width in millimeters
- 60 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 18 is a wheel diameter (or rim) in inches
How to convert LT265 60R18 to inches?
First of all, we need to divide 265 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 10.4″. Then, 60% of the 10.4″ will result in 6.3″ sidewall.
To get the total height or tire diameter, we need to sum the 18″ rim diameter with two of the sidewall heights. It will result in a 30.6″ total tire diameter (or height).
For your convenience, below is a table for LT265/60R18 conversion to inches:
