17 Inch Metzeler Semi ME22 3.00X17

The sizes of tires we sell are indicated in 2 different sizes. Metric, like for example 80/90/17 and inches like for example 2.50X17.

Metric
For metric sizes, the first number stands for the width in mm, the second number represents the height of the tire as a percentage of the width. The third number stands for the inch size of the rim.
For example, an 80/90/17 is 80MM wide, 72MM high (90 percent of 80) and has an inch size of 17.

Inch
For inch sizes, the first number stands for the width in inches ( one inch is 2.54 CM ), the second number stands for the inch size of the rim.
For example, a 2.50 X 17 is 63MM wide (2.50 X 2.54CM) and has an inch size of 17.

Below you will find a comparison table with the relevant sizes. This can be useful, for example, if you now have a tire with an inch indication and would like a tire from our range that has a new size.

From Inch to Metric

• 3.00 X 12 = 80/90/12
• 2.00 X 16
• 2.25 X 16
• 2.50 X 16 = 70/90/16
• 2.75 X 16 = 80/90/16
• 2.00 X 17
• 2.25 X 17 = 70/90/17
• 2.50 X 17 = 70/90/17
• 2.75 X 17 = 80/90/17
• 3.00 X 17 = 90/90/17
  
  

New and old tire sizes
Some old tires that come off an old moped still have an old way of sizing on them. Below you can see the new dimensions and the old designation so that you can choose the right replacement.

• 2.75 X 17 = 21 X 2.75
• 2.00 X 17 = 21 X 2.00
• 2.00 X 19 = 23 X 2
• 2.25 X 19 = 23X2X2.25
• 2.50 X 19 = 23X2X2.50

Rim sizes
We also have rims in different sizes, these are the same in inch size but different in width.
Therefore, below is an overview of how a rim size can be linked to a tire size:

A 1.20 rim is 44mm wide for a tire size of 2.00/2.25
A 1.35 rim is 48mm wide for a tire size of 2.25/2.50
A 1.50 rim is 55mm wide for a tire size of 2.75
A 1.60 rim is 58.50mm wide for a tire size of 3.00
A 1.85 rim is 68mm wide for a tire size of 3.25/3.50
A 2.15 rim is 76mm wide for a tire size of 3.50
A 2.50 rim is 83mm wide for a tire size of 4.00

For example: A 1.60X16 rim needs a tire size 3.00X16

These sizes apply to the most common rims, of course something can be deviated from
