T105/80D13 — what does it mean?
- T means "temporary"
- 105 stands for tread width in millimeters
- 80 is an aspect ration between the tread width and the sidewall in percents
- D means that the tire has a diagonal construction
- 13 is a wheel diameter (or rim) in inches
How to convert T105 80D13 to inches?
First of all, we need to divide 105 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 4.1″. Then, 80% of the 4.1″ will result in 3.3″ sidewall.
To get the total height or tire diameter, we need to sum the 13″ rim diameter with two of the sidewall heights. It will result in a 19.6″ total tire diameter (or height).
For your convenience, below is a table for T105/80D13 conversion to inches:
|Overall diameter (height)||19.6″||498 mm|
|Tread width||4.1″||105 mm|
|Wheel diameter||13″||498 mm|
|Sidewall height||3.3″||84 mm|
