T155/90D16 — what does it mean?
- T means "temporary"
- 155 stands for tread width in millimeters
- 90 is an aspect ration between the tread width and the sidewall in percents
- D means that the tire has a diagonal construction
- 16 is a wheel diameter (or rim) in inches
How to convert T155 90D16 to inches?
First of all, we need to divide 155 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 6.1″. Then, 90% of the 6.1″ will result in 5.5″ 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 27″ total tire diameter (or height).
For your convenience, below is a table for T155/90D16 conversion to inches:
|Overall diameter (height)||27″||686 mm|
|Tread width||6.1″||155 mm|
|Wheel diameter||16″||686 mm|
|Sidewall height||5.5″||140 mm|
|Revolutions||747 / ml||464 / km|
