Off-the-Road (OTR) tyres are the backbone of industries like mining, construction, and material handling. They carry massive loads, face rough terrains, and work under extreme conditions — which means replacing them frequently can be very expensive.
Fortunately, OTR tyre retreading is a proven solution that restores these tyres to near-new condition, saving costs and reducing waste. But how exactly does the process work? Let’s break it down step by step.
Step 1: Initial Inspection & Casing Selection
The first step is to thoroughly inspect the worn-out tyre. Experts check for:
- Sidewall integrity
- Bead damage
- Excessive cuts or cracks
- Internal separations
Only casings that meet strict safety and quality standards move forward for retreading. This ensures the retreaded tyre will deliver safe and reliable performance.
Step 2: Buffing the Tyre
Once the casing is approved, the old tread is carefully buffed away using precision machinery.
- This removes the worn rubber.
- Creates the ideal surface texture for new tread bonding.
- Maintains the original profile and balance of the tyre.
Proper buffing is crucial for long-lasting results.
Step 3: Repair & Preparation
Any minor cuts, nail holes, or surface damages are repaired. Skives and fillings are used to restore the casing to its best possible condition.
This stage ensures that the tyre is structurally sound before applying the new tread — preventing future failures.
Step 4: Applying New Tread
A new layer of high-quality tread rubber is applied to the prepared casing using either:
- Precure (Cold) Retreading – where pre-cured tread strips are bonded to the casing.
- Mold Cure (Hot) Retreading – where uncured rubber is applied and then vulcanized in a mold.
For OTR tyres, hot retreading is often preferred for maximum durability and strength.
Step 5: Curing & Vulcanization
The tyre is placed into a curing chamber, where heat and pressure are applied.
- This process bonds the new tread to the casing.
- Ensures a seamless, strong connection that can withstand heavy-duty use.
Step 6: Final Inspection & Quality Check
After curing, every retreaded tyre undergoes a final inspection:
- Tread depth and profile are checked.
- Tyre balance and roundness are verified.
- Visual and x-ray inspections may be performed for extra safety.
Only tyres that pass these checks are approved for delivery.
Benefits of Retreading OTR Tyres
✅ Cost Savings: Retreading costs 40–50% less than buying new tyres.
✅ Extended Life: High-quality retreads deliver performance close to new tyres.
✅ Eco-Friendly: Each retread saves hundreds of kilos of raw materials and reduces landfill waste.
