Maximising Tyre Performance, Lifespan, and Safety in OTR Vehicles through Pressure Maintenance!


Introduction to OTR Tyre Management
Off-the-road (OTR) tyres are pivotal to the functionality and productivity of heavy-duty vehicles. They play a crucial role in supporting the vehicle’s load, ensuring traction and braking, directing travel, absorbing road shocks, and overcoming various road challenges. At Tyre Response Group, we understand the critical nature of these components in your fleet’s performance and your bottom line.

Maintaining Optimal Tyre Shape
Achieving the best performance from your tyres involves maintaining their optimal shape, primarily through correct tyre inflation. Proper inflation ensures the tyre can deflect appropriately under load, creating an ideal footprint for maximum traction and longevity while also resisting sidewall damage and minimising heat generation.

The Risks of Overinflation and Underinflation
Overinflating tyres can lead to uneven load distribution, increased susceptibility to damage, and reduced traction. Conversely, underinflation, or effectively overloading the tyre, leads to excessive heat, uneven wear, and increased stress on the tyre structure. Both conditions significantly reduce tyre lifespans and can pose safety hazards.

Determining the Correct Inflation Pressure
The appropriate inflation pressure for a tyre depends on its intended application, indicated by the tread code (e.g., G-Grader Service, E-Earthmover Service, L-Loader/Dozer Service). Factors like operational cycle speed, distance, and load also influence the optimal inflation pressure. It’s crucial to consult with tyre experts like TRG and tyre manufacturers to customise this pressure to ensure you are getting the most out of your OTR tyres.

Understanding Cold vs Hot Inflation Pressure
Inflation pressure should ideally be set when the tyre is at ambient temperature, known as ‘cold inflation pressure’. Hot inflation, measured during or after the operation, will be higher due to heat expansion. Adjustments may be necessary depending on the operational and environmental temperatures.

The Importance of Correct Inflation Pressure
Maintaining the correct inflation pressure is essential for optimal tyre performance, maximising tyre life, and ensuring safety. Whether managed manually through pressure checks or remotely via TPMS, maintaining tyre inflation is a critical aspect of operational management.

Proper tyre management, particularly in maintaining the correct inflation pressure, is key to maximising the performance and lifespan of your OTR tyres. At Tyre Response Group, we’re committed to providing expert guidance and solutions to ensure your fleet operates at its best.
