345/85R16 — what does it mean?
- 345 stands for tread width in millimeters
- 85 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 16 is a wheel diameter (or rim) in inches
How to convert 345 85R16 to inches?
First of all, we need to divide 345 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 13.6″. Then, 85% of the 13.6″ will result in 11.5″ sidewall.
To get the total height or tire diameter, we need to sum the 16″ rim diameter with two of the sidewall heights. It will result in a 39″ total tire diameter (or height).
For your convenience, below is a table for 345/85R16 conversion to inches:
|Overall diameter (height)||39″||991 mm|
|Tread width||13.6″||345 mm|
|Wheel diameter||16″||991 mm|
|Sidewall height||11.5″||293 mm|
|Revolutions||517 / ml||321 / km|
