Everything you need to know about MICHELIN Earthmover tyres
The tyre is the only point of contact between the machine and the ground. You must make sure that the quality and performance of your tyres are maintained to guarantee their performance and your safety.
Read the markings carefully
The markings on the sidewalls of your tyres give information and guide you in the choice of product best suited to your needs.

Choose your tyres carefully
Choosing the right MICHELIN Earthmover tyre is essential to ensure that its performance is optimised.
Step 1: Define your use
The international classification defines 4 types of use. The classification of its use is indicated on the tyre sidewall.
- C : Compactor
- G : Grader
- E : Earthmoving
- L : Loader and bulldozer
Step 2: Analyse your conditions of use and the nature of the surface
There are different depths and shapes of tread pattern. The choice of the type of tread pattern depends mainly on the surfaces or haul roads encountered: grip, risks of cuts, rapid wear. The optimum performance of the machine depends to a large extent on the choice of tyre. The most suitable MICHELIN solution will vary according to your environment.
- 1 : Ribbed (normal trad depth)
- 2 : Traction (normal treadd depth)
- 3 : Normal (normal treadd depth)
- 4 : Deep : (deep tread)
- 5 : Very deep (very deep tread)
- 7 : Flotation (normal tread)
Step 3: Know your TKPH
To select the right tyre, you need to know your TKPH. The TKPH (Tonne Kilometers per Hour) or TMPH (Tonne Miles per Hour) is in effect an essential characteristic of the working capacity of your tyres. For the same tyre size and tread pattern, there may be several types of rubber, each one associated with a different TKPH.
The TKPH and TMPH values are part of the tyre characteristics.
They depend on the load capacity specific to each tyre size, the number of kilometers permitted in an hour by type of tyre, and are given for a standardised ambient temperature of 38 °C.
Fitting and removing a tyre correctly
Correct fitting, carried out in accordance with the methods of work recommended and observing the safety rules in force provides protection for both personnel and equipment and enables the tyre’s full potential to be used. Incorrect fitting may result in damage to the tyre, the vehicle and/or people (serious or even fatal injury).
It is therefore imperative to have these operations performed by trained personnel with the appropriate equipment at their disposal.
For further information, see the Use and Maintenance Guide for MICHELIN Earthmover tyres.
Maintain your tyres correctly
Tyres must be inspected regularly to detect any irregular wear or possible damage. Any perforations, cuts or deformations visible on the tread, sidewalls or bead zone must undergo in-depth examination by a tyre professional.
The same applies to any damage to the wheel.
Tread depth must always be checked at several points on the tyre.
This check can be carried out using a depth gauge or by observation of the wear indicators in the tread (identified by a symbol on the shoulder when present).
Inflate your tyres correctly
Correct tyre inflation is an essential factor, not only as regards the optimisation of tyre performance, but also as regards safety. Correct pressure is necessary for correct machine handling (traction, braking) and for maintaining the tyre’s integrity.
Under-inflation and over-inflation, may have a significant effect on tyre performance. An inadequate tyre pressure leads to an abnormal rise in operating temperature and may result in irreversible damage to internal components and cause the destruction of the tyre and rapid tyre deflation.
Excessive pressure can cause rapid and irregular wear and lead to increased susceptibility to impacts (tread damage, casing failure).
The inflation pressure which must be observed is the pressure recommended by the tyre manufacturer.
The pressure for a Michelin tyre can only be given by your Michelin contact or by a tyre professional who will take into account the tyres condition of use (type of machine, nature of surface, cycle length, materials transported, loads, etc.).
Repair your tyres properly
All repairs must be carried out by a trained and qualified professional. Repair is systematically preceded by a meticulous inspection of the tyre by the professional.
Not all kinds of damage can be repaired. A tyre which has run under-inflated or flat may have suffered irreversible damage, and only an exhaustive verification of the tyre’s interior can decide whether or not the tyre is going to be suitable for repair.
It is essential that the tyre is removed so that a sound judgment can be made regarding its true condition and the type of repair to be made.
Store tyres carefully
Storage must take place:
- In clean, airy, dry, temperate and well-ventilated premises, sheltered from direct sunlight and bad weather;
- Remote from any chemical substance, solvent or hydrocarbon likely to alter the nature of the rubber.
- Well away from any object which might penetrate the rubber (metal spike, wood, …);
- Distant from any source of heat, naked flames, incandescent bodies, equipment likely to emit sparks or electric discharges and any source of ozone (transformers, electric motors, welding sets, etc.).
Incorrect tyre handling may cause irreparable damage, and may also have serious or even fatal consequences for the operator. With the aim of eliminating the risks of damage to the beads and the possible consequences, our advice is:
- do not lift a tyre directly with the hook of a crane;
- use flat straps (not metal slings or chains);
- pick the tyre up under the tread, not the beads when using a fork lift truck;
- comply with the safety instructions in force at the site.
Operators must be wearing suitable personal protective equipment.
