Earthmover tyre repair


The harsh conditions in which earthmover tyres are used often cause slight and occasionally serious, damage. MICHELIN earthmover tyres are designed with repairability in mind, allowing certain types of damage to be repaired effectively. However, it is essential to note that tyre repairs should always be carried out by trained professionals, as they bear full responsibility for the quality and safety of the repair work performed.

What are the factors contributing to earthmover tyre wear? 

Understanding the various factors that contribute to tyre wear is essential for maximising the lifespan and performance of earthmover tyres. Tyres endure significant stress due to the demanding conditions they operate in, making them susceptible to accelerated wear if not properly managed. Here are some examples of factors that can cause wear on earthmover tyres:

  • Excessive Loads: Overloading the machinery beyond the tyre's load capacity can cause excessive stress and premature degradation.
  • Incorrect Tyre Pressure: Operating with under-inflated or over-inflated tyres can lead to uneven wear, reduced traction and increased vulnerability to punctures. 
  • Friction and Scrubbing: Frequent turning on hard surfaces or tight manoeuvring can cause excessive friction, leading to faster wear, especially on the tyre's outer edges.
  • Environmental Conditions: Exposure to harsh weather conditions, such as extreme heat or cold, as well as corrosive materials on job sites, can adversely affect tyre longevity.

How to repair earthmover tyres? 

  • Identify if the tyre can be repaired. Not all kinds of damage can be repaired. Certain types of damage, such as severe sidewall punctures, deep cuts, excessive tread wear or any structural deformities that compromise the tyre's integrity, typically cannot be repaired. A tyre that has been run under-inflated or flat may have suffered irreparable damage and only an exhaustive check of the inside of the tyre will reveal whether or not it can be returned to service. It is therefore essential to remove the tyre to assess with certainity its actual condition and the type of repair to be carried out.

STEP 1: The qualified tyre professional should first perform a detailed inspection of the tyres: 

  • Examine the damage (position, proximity to other damage, ...)
  • Size of the damage, defining the dimensions of the repair, will determine the repairability of the tyre and, if it is repairable, the materials and products to use.
  • Repair dimensions, a determining factor in the choice of patches

STEP 2:  The qualified tyre professional sould repair the tyre if the feasibility is confirmed.

Repairs are carried out using the "cold cure" or "hot cure" process:

  • The "cold cure" or self-curing repair process does not require any external heat source other than that of the surrounding environment (as long as the temperature is 64°F • 18°C or more).
  • The "hot cure" repair process requires the addition of external heat to cure the rubber and create the bonds between the various components. The products must be suitable for the equipment used and it is essential to keep strictly to the recommended temperatures. 

To summarise

Earthmover tyres often suffer minor to severe damage due to harsh operating conditions. MICHELIN tyres are designed to be repairable. Repairs should only be carried out by qualified professionals who are responsible for the quality and safety of their work. Assessment of the tyre's condition is essential, as some damage may be irreparable. To learn more about the maintenance and repair of earthmover equipment, feel free to download our e-book.
