How Do I Read My Earthmover Tyre Size?

There are several methods for giving the size of earthmover tyres, with measurements sometimes given in inches, sometimes in millimetres, or sometimes in both! so our Tyre Size Guide is a helpful read to understand them. The examples and explanations given below should hopefully make it possible for you to recognise your own size markings.

Example 1:  17.5-25, 20.5-25, 23.5R25

The first number i.e. 17.5, tells you the width of the tyre (called the SECTION WIDTH).  The '-' means the tyre is of CROSSPLY construction (Radial construction would be represented by an 'R'). The final number, 25, is the RIM Diameter in inches. So a 17.5-25 earthmover tyre would be around 17.5 inches wide,  fit on a 25 inch diameter rim/wheel, and be of Crossply construction. 

Example 2:  650/65R25, 750/65R25

The first part is the width (SECTION WIDTH) of the tyre in mm, the second part, is the PROFILE of the tyre (height of the sidewall expressed as a percentage of the width), and the third number is the rim diameter (RIM SIZE) in inches. The 'R' when present within the size, means the tyre is of RADIAL construction, whereas the '-' shows its of CROSSPLY construction. So a 650/65R25 is 650mm wide (SECTION WIDTH), has a PROFILE of 65%, is of RADIAL construction and fits a 25 inch rim (RIM SIZE is 25"). A 750/65R25 tyre would be 750mm wide, have profile of 65% and fit a 25" diameter rim/wheel, and be of Radial construction.


Can You Fit My OTR Tyres?

Our tyre fitting service is a mobile onsite service where a fitter can be booked to come to you after your tyres have been delivered by our couriers. A call out fee and tyre change fee is charged.

Foam filling of earthmover tyres is very popular as these tyres of tyre are often used in recycling, waste or scrap metal yards. Foam filling your earthmover tyre is a great way to extend tyre life, save on machinery downtime and the hassle of booking punture repairs. It can cost a chunk of money, often as much as a new tyre itself, but it is cheaper than converting to pure solid rubber tyres and still offers some cushioning which is better for rider comfort and machine maintenance. 


OTR Tyre Tread Types Available

The tread pattern is designed to produce varying degrees of traction, cut, flotation, wear and heat resistance. So selection of the proper Off-the-Road tire depends on the job and the conditions. For example, different tread patterns are used to produce maximum traction or flotation on sand, mud and rock. There are five basic tread patterns: rock, traction, block, rib and smooth.

Rock Pattern

Rock Pattern Rock Flush Pattern Rock patterns are specially designed to prevent cuts caused by shark rocks. Their large ground contact area provides excellent wear resistance ensuring long lastability. Characteristic grooves running across the direction of the travel mark the most popular tread pattern for OTR tyres.

Block Pattern

Block The block pattern tyre is mostly characterized by wide tread width and rounded shoulders. Under heavy loads, the block pattern's large ground contact area creates low ground contact pressure, for good flotation properties. Therefore, it is well suited for use on soft, muddy ground. This pattern is also called the "alligator" or "button" pattern.


Traction Pattern

Traction Traction patterned tyres have a directional tread design, this means the direction that you mount the tyre onto the rim is important. The mounting direction should place the tread facing one way on the drive wheels to produce proper traction.

Smooth Pattern

Smooth Smooth Loader The smooth pattern tyre, designed for tyre rollers, has no grooves. It is used for compacting and leveling. A smooth pattern tyre is also be used on loaders in underground mines because of its high wear and cut resistance. The smooth pattern for loaders, however, has two narrow grooves that are used to measure tread wear.


OTR Tyre Speed and Load Indexes Explained

A tyre's Speed Index is the maximum safe speed of the tyre; this is represented with a letter from the very slow (A1) to the very fast (Y and beyond). The Load Index is the maximum weight that the tyre can safely support. This is represented by a number: the higher this number is the more weight the tyre can carry. It is imperative for the safety of the vehicle and its occupants that tyres with high enough Speed and Load Indexes are chosen. To find out more about Speed and Load Indexes and all other tyre markings, have a look at our Tyre Size Guide.
