Reading the size
In a metric size such as 80/100-21, the first number is the nominal section width in millimetres and the second is the aspect ratio: the sidewall height as a percentage of that width.1
The number after the dash is the rim diameter in inches. The load index and speed rating that follow (for example 51M) are read together: the number maps to a maximum load and the letter to a maximum speed in the tire maker’s charts.12
Before you order
Dunlop points out that a larger load index means the tire can carry more weight, and advises comparing the tire code with your bike’s specifications so the tire can handle its weight and speed.2
The stock sizes in the table above come from each bike’s manual or spec sheet. Check the sizes printed on your own tires as well: a previous owner may have changed them. The tire size decoder reads any size for you.
