LT355/40R22 — what does it mean?
- LT means "light truck"
- 355 stands for tread width in millimeters
- 40 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 22 is a wheel diameter (or rim) in inches
How to convert LT355 40R22 to inches?
First of all, we need to divide 355 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 14″. Then, 40% of the 14″ will result in 5.6″ sidewall.
To get the total height or tire diameter, we need to sum the 22″ rim diameter with two of the sidewall heights. It will result in a 33.2″ total tire diameter (or height).
For your convenience, below is a table for LT355/40R22 conversion to inches:
|Overall diameter (height)||33.2″||843 mm|
|Tread width||14″||355 mm|
|Wheel diameter||22″||843 mm|
|Sidewall height||5.6″||142 mm|
|Revolutions||608 / ml||378 / km|
