How do I find the tyre size for my earthmoving machine?

A lot of information about tyres can be found on the sidewall of a tyre. Large earthmover tyres form no exceptions for this rule. On the sidewall you can find the tyre width (first digits) followed by a slash (/). The digits after the slash indicates the tyre height as a percentage of the width. A letter indicates the type of tyre (Diagonal or Radial) and the last number indicates the rim size. For instance: 385/95R25

With Earthmover tyres/OTR it is also possible that the tyre information consists of: a number (Tyre width) followed by a letter (R or D) and after that another digit (rim size)For instance: 17.5R25

The TRA code of an Earthmover Tyre

A TRA code in an earthmover tyre consists of a number and letter combination. Often this combination consists of a letter, followed by a number and possibly another letter.TRA code is an international benchmark recognised by international organisations such as the ISO and JATMA
The first letter shows the tread profile, the second figure indicates the tread depth and the last letter says something about the profile / pattern of the earthmoving tyre.

The different tread patterns of Earthmover tyres

Earthmoving machines are used for various task and enviroments. Each machine has its own specific tread pattern. This tread pattern is indicated by letters according to the TRA guidelines.We can categorise the tyres in 4 categories:

E: Dumptrucks are equipped with tyres with thread pattern E.
G:Tyres with a tread pattern G are mounted onGraders.
L:Loaders and Dozers need tyres with threadpattern L.
C:Compacting machines use C tyres.

Thread depth of Earthmover Tyres

A TRA code also consists of a thread depth.

A number 2 or 3 shows that the tread depth is 100%.
Number 4indicates that the profile depth is 150%.
Number 5indicates that the tyre has 250% profile depth

Earthmover Tyre profile

Earthmover Tyres can have 3 different profiles:

T = Traction, these tyres offer extra high traction.
R = Rock, these tyres are good for stone-rich environments. These tyres are better protected against sharp stones and are less prone to cutting.
S = Smooth, also known as slicks. These tyres offer a little amount of tracion but are extremely well protected against cuts form sharp stones.
