The letters "OTR" stands for "OFF THE ROAD". The OTR tires are specially designed for equipment and vehicles used in mining, quarrying, construction, industrial and port handling. These tires are adapted to deliver excellent traction on uneven, muddy, or icy road surfaces, bearing heavy loads while providing high resistance to wear and heat build-up.

💡 Classification of OTR Tyres

1. Tyre and Rim Matching

Ensure rim sizes are identical to those on sidewalls. Only fit tyres to standard or allowable rims. Never use deformed or non-conformity rims.

2. Inflation Pressure

Follow standard rules for inflation. Check pressure regularly and replenish when insufficient. Overpressure or underpressure can cause decreased loading capacity or dangerous blowouts.

3. Load Management

Select the corresponding ply rating based on the vehicle's standard capacity. Distribute load evenly across the vehicle.

The Ton Kilometre Per Hour (TKPH) factor determines the suitability of a tyre for specific operations. The maximum operating TKPH should not exceed the tyre's rating.
