Important factors affecting OTR tires service life

2021-08-13

Dongying Haorun tells you that the important factors that affect the service life of OTR tires, let's take a look at these aspects from the aspects of load, air pressure, temperature, and driving conditions!

1. Load

Assumption; the service life of the OTR tires under normal load is 100%
When overweight by 30%, the service life of the tire is 60% of the normal value

When overweight is 50%, the service life of the tire is 40% of the normal value


2. Air pressure
If the tire pressure is too high or too low, it will affect the life of the tire.
When the air pressure is 25% higher than the normal value, the tire life will be reduced by 10% - 15%,

When the air pressure is 25% lower than the normal value, the tire life will be reduced by 20%


3. Temperature
Assumption: Take 30 degrees of OTR tires as the standard value, tire wear life is 100%;
When the tire temperature is 50 degrees, the wear life of the tire is 80% of the normal value;

When the tire temperature is 70 degrees, the wear life of the tire is 70% of the normal value


4. Driving road conditions
Assumption; Taking the smooth cement road as the standard, the OTR tires wear-resisting life is 100%
When the vehicle is running on an ordinary paved road, the tire wear life is 90% of the normal value
When the vehicle is running on part of the gravel road, the tire wear life is 70% of the normal value
When the vehicle is running on sand and gravel roads, the tire wear life is 60% of the normal value

When the vehicle is running on a non-paved road, the tire wear life is 50% of the normal value
