Our Earthmover & Mining range covers tyres for heavy machinery like graders, loaders, dozers & dump trucks. We offer premium brands including Michelin, Continental & Trelleborg, mid-range brands such as Camso & BKT, and value brands like Double Coin, Dynamaxx & Triangle.

Search our earthmoving & mining tyre range using our tyre finder below, all you need is your tyre size to start. Ensure you later filter your results to only display tyres that match or exceed your current tyres load & speed rating. Please note we do not currently offer fitting for heavy earthmover tyres. Please contact us should you need any advice or assistance.

Search Earthmover & OTR Tyres



Your tyre size will almost always be written on the tyres sidewall. There are several formats of earthmover tyre size, with measurements sometimes given in inches, sometimes in millimetres, or sometimes in both. The example sizes and explanations below should help you to recognise and understand your own size markings.

  • 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 '-' symbol means the tyre is of 'Crossply' construction, whereas an 'R' represents 'Radial' construction. 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.

  • 650/65R25, 750/65R25 - The first number is the tyre width (Section Width) across the tyre in mm, the second number after the '/' is the tyres 'Profile' (the height of the sidewall expressed as a percentage of the tyres width), and the last number is the 'Rim Diameter' in inches (the diameter of the hole in the centre of the tyre). If an 'R' is present in the size it means the tyre is of 'Radial' construction, whereas a '-' symbol signifies its of 'Crossply' construction. So a 650/65R25 is roughly speaking 650mm wide, with a sidewall profile of 65%, is of Radial construction, and fits a 25 inch diameter wheel rim.

Earthmover tyres come in a mix of tread designs that produce varying degrees of traction, flotation, cut, wear and heat resistance. These tread varieties are needed for the different ground conditions that earthmoving equipment commonly operates in, such as sand, mud and rock. The four basic tread patterns are traction, rock, block & smooth.

Earthmover Tread Pattern Types

 Traction pattern tyres provide excellent traction and manoeuvrability on soft or muddy ground. These tyres are available in directional open lug tread patterns designed for maximum traction on loading shovels, graders and other earthmover machinery, and in slightly more closed block lug tread patterns, which whilst not as aggressive, do still allow an adequate amount of grip whilst providing more impact damage protection.

ROCK PATTERN:  Rock patterns are specially designed to resist cuts and prevent impact damage from sharp rocks and other large aggregates. Their large ground contact area and characteristic deep lug tread patterns also provide excellent wear resistance ensuring a long service life.

BLOCK PATTERN:  Block pattern tyres have multi block tread patterns and provide flotation and traction on yielding surface conditions such as sand, gravel and mud. Their larger tread footprint spreads the ground contact pressure accross the grounds surface.

SMOOTH PATTERN:  The smooth pattern tyre is designed for underground mining machinery, compacters, rollers and other earthmover machinery, such as loading shovels that run on hard surfaces like concrete or asphalt. They can be completely smooth, often when designed to be used on rollers, or can have a narrow groove on them to indicate tread wear for when used on loaders.

TRA codes are internationally standardised letter codes that advise you which type of machine and purpose a tyre should be used for. They are extremely useful when choosing earthmover / OTR tyres, and you should select the appropriately marked tyres for your required application and useage. A TRA code will normally be stamped on the sidewall of your current tyre.

TRA codes are simple to understand. They always have a letter followed by a number, and can also occasionally end with another letter, such as G2, L3, E4R, L5S. The first letter advises the type of machine the tyre can be used (Grader/Loader etc). The number advises the tyre tread depth (standard, deep, extra deep). The final letter, if present, advises for which purpose the tyre is best suited (rock, traction etc).

Letter Code

  • C = Compactor (road-building machines and steam rollers)
  • L = Loader/Dozer
  • G = Grader
  • E = Earthmoving (transport, scrapers, articulated and rigid dump trucks)
  • IND = Industrial (port)

Digit Code

  • 2 or 3 = 100% tread depth (standard tread)
  • 4 = 150% tread depth (deep tread)
  • 5 = 250% tread depth (extra deep)

End Letter Code

  • T = Traction - Tyres with a fairly open pattern offering very good traction.
  • R = Rock - Tyres with a more closed pattern, offering less traction, but but more protection from cuts. 
  • S = Smooth - Tyres with no tread pattern, offering no traction, but very high resistance to cuts.

TRA codes are recognised as an international benchmark. They are validated by the ISO (International Standard Organisation), the ETRTO (European Tyre and Rim Organisation), the TRA (Tyre and Rim Association) and the JATMA (Japan Automobile Tyre Manufacturers Association).

OTR and Earthmover tyres are usually very heavy and can be more difficult to transport and handle. Fitting earthmover tyres safely often requires two fitters and a mobile crane. As a rule our standard nationwide tyre fitting service doesn't usually cater for heavy earthmover tyres. This is due to the difficulty and variability in predicting the number of man-hours that will be required to complete some jobs, along with the specific tooling and skilled technicians not alway being available in certain regions of the country. If you are looking to purchase earthmoving or OTR tyres but are unable to do so without a fitting service, you can call to speak to our friendly sales teams to ask if we can help in your specific instance. It is common to be charged between £200-£500 per tyre fitted, depending on the tyre size, the vehicle & it's location.

Tyre sealant is often used in earthmoving tyre as a preventative measure to improve up-time and eliminate puncture related down-time. You can protect your earthmoving vehicle fleet for a fraction of the costs normally associated with puncture repairs or tyre replacements. Tyre Sealant comprises of a carefully formulated blend of natural fibres, blocking agents and sealing compounds that have been proven to seal punctures up to and above 18mm. It can be used as a preventative measure for wide a range of OTR vehicles and in different tyre sizes. Find out more on our Tyre Sealant Information Page.
