LT395/65R18 — what does it mean?
- LT means "light truck"
- 395 stands for tread width in millimeters
- 65 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 LT395 65R18 to inches?
First of all, we need to divide 395 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 15.6″. Then, 65% of the 15.6″ will result in 10.1″ 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 38.2″ total tire diameter (or height).
For your convenience, below is a table for LT395/65R18 conversion to inches:
|Overall diameter (height)||38.2″||970 mm|
|Tread width||15.6″||395 mm|
|Wheel diameter||18″||970 mm|
|Sidewall height||10.1″||257 mm|
