Effecting a perfect repair means your tyre can be returned to service whether that be haulage, loader, dozer, farming and logging, or over-the-road transport. This makes repair quality an important driver of tyre lifespan and a critical factor for maximising budget efficiency.
So how do you achieve this?
1. Use quality supplies
Only use quality products – from tools to rubber, patches and vulcanizing equipment.
2. Train the team
Ensure technicians are properly trained in all aspects of the tyre itself as well as the repair process. Do they understand…
- the function of the tyre?
- how all the tyre components – tread, sidewall, bead, bead wires, body plies etc – work together?
- the correct way to use all tools and equipment?
- how to properly build up and install a repair to ensure maximum adhesion?
- the best protocols for safe working?
- the importance of a clean working environment and how to achieve?
3. Inspect the injury
Include a comprehensive inspection process assessing the injury’s size and its location in the tyre:
- Is there an economic case for making the repair i.e. what is the general tyre condition? How much tread is remaining?
- Is there more than one injury/ less obvious damage to consider?
- How far below the surface does the injury extend?
4. Assess the repair
Consider the following:
- What tools are required?
- How can you remove the structural damage?
- What is the correct skive angle and buff texture?
- When is a repair unit required? What is the right patch? Make sure you consult patch manufacturer application charts.
- What is the best and safest method of using the chosen vulcanizing system?
5. Understand your vulcanising system
Get to know your OTR or Truck vulcanising system.
- Get the right training and adhere to best practice usage guidelines
- Use the correct components for the job to ensure a perfect fit and optimum results. Always consult component application charts
6. Conduct a final inspection
This stage is as important as the initial inspection.
- Did the technician find and repair all damage?
- What does the repair look like? Are there signs of under cure, bubbles or separation
- Record the shore hardness
- Can you return the tyre to its original operation?
- Should the repaired tyre should be down-graded usage wise? Example: Install a haulage tire on a slow-moving water-wagon versus a high speed truck that travels great distances at high speeds
