product. Sumitomo Rubber SA has an In field Technical Services (ITS) team located in different regions, including Africa, dedicated to advising customers on tyre selection, application, and performance. Their expertise can make a significant difference in your business growth and help you maximise the performance of your tyres. Additionally, consider doing a scrap tyre analysis to identify the reasons behind their failures or removal due to operational damage. Fleet surveys can offer valuable insights, including a detailed examination of tyre wear patterns and potential mechanical irregularities in the vehicles causing tyre wear. Check load capacity Heavy-duty trailers demand tyres that can handle substantial weight. Before making a purchase, make sure to check the maximum load rating of your trailer and choose tyres accordingly. When dealing with heavy loads or large equipment, it is crucial to make sure that your load distribution per axle is correct. This ensures proper weight distribution onto the tyres, resulting in optimal tyre performance. This can be done by conducting a load study on the truck and trailer, which will determine the weight of each axle. Once this has been done, the correct

QUICK TAKE

Tread depth plays a crucial role in a tyre’s performance, especially in wet conditions

For heavy loads or large equipment, the load distribution per axle needs to be correct

Pressure maintenance is crucial in reducing rolling resistance and optimising fuel efficiency

Factors that affect fuel consumption include cold inflation pressures, wheel alignment and the trailer’s mechanical condition
