Conversion for Tractor Tires

 


The size of the tire can be signed in inches or millimetres.
For example 16.9 R34 is an inch size the equivalent size signed in mm is 420/85 R34. This is exactly the same size, the only difference is how the size is written!


The tire size can be composed with two sets of numbers, for example:
6.50-16, 12.4-24 or 18.4-38
1. number 6.50-16 is the width in inches
2. number 6.50-16 is the diameter of the rim.

A tire size can be composed also in three sets of numbers:
like 16x6.50-8, 31x15.50-15.3 or 25x12.00-12
1. number 16x6.50-8 is the height
2. number 16x6.50-8 is the width,
3. number 16x6.50-8 is the size of the rim.



If you search in our system we show you the results also in the equivalent size (inch to mm / mm to inch). In this table you will find also your equivalent size for low section tyres like 480/70R34


650/65R38
650 = Width of the tyre in mm (side-wall to side-wall, not the pattern-size!)
65 = Height percentage of width (650mm x 0.65= 422.5mm)
R = for Radial Tyres
38 = Diameter in Inch
