LT325/60R18 — what does it mean?
- LT means "light truck"
- 325 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 LT325 60R18 to inches?
First of all, we need to divide 325 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 12.8″. Then, 60% of the 12.8″ will result in 7.7″ 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 33.4″ total tire diameter (or height).
For your convenience, below is a table for LT325/60R18 conversion to inches:
|Overall diameter (height)||33.4″||848 mm|
|Tread width||12.8″||325 mm|
|Wheel diameter||18″||848 mm|
|Sidewall height||7.7″||195 mm|
|Revolutions||605 / ml||376 / km|
