LT275/65R20 — what does it mean?
- LT means "light truck"
- 275 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
- 20 is a wheel diameter (or rim) in inches
How to convert LT275 65R20 to inches?
First of all, we need to divide 275 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 10.8″. Then, 65% of the 10.8″ will result in 7″ sidewall.
To get the total height or tire diameter, we need to sum the 20″ rim diameter with two of the sidewall heights. It will result in a 34″ total tire diameter (or height).
For your convenience, below is a table for LT275/65R20 conversion to inches:
|Overall diameter (height)||34″||864 mm|
|Tread width||10.8″||275 mm|
|Wheel diameter||20″||864 mm|
|Sidewall height||7″||179 mm|
|Revolutions||594 / ml||369 / km|
