When checking the state of your tyres you notice irregular wear in several places around dual tyres, especially on the drive axle. The inner tyres show significant wear on the tread shoulder.
This may be due to:
- The camber angle
- The type of suspension
- The use
- An excessive load on an axle
- A high centre of gravity
To remedy this, it is recommended to:
- Check the tyre pressure and adjust it based on the tyre manufacturer ‘s recommendations and the vehicle’s use
- Check that the tyre is suitable for its use
- Weigh each axle of the loaded vehicle to determine the right tyre pressure
- Rotate the tyres and turn them on the rims.
If the tyre continues to comply with the regulations and if the vehicle still handles “normally”, it can remain in service.
Things to know
The camber is the angle between the wheel and the road. If two dual tyres do not have the same camber, they are not parallel to each other and therefore rub against each other or do not run parallel to the road. As such, they may wear prematurely.
An incorrect camber angle and an axle bending under heavy load, combined with a rounded tyre, may result in accelerated shoulder wear of the inner dual tyre.
