Damage can also occur as a result
of an accident or hitting a solid object in or at the side of the road such as a concrete kerbstone. Always stop at a safe designated area to inspect your tyres and rims in the event that you have driven over something that could have damaged a tyre or rim.
HOW IMPORTANT IS WHEEL BALANCING? Wheel balancing is very important. If wheels are left unbalanced, excessive vibration, in time, can work wheel
nuts loose, which in turn could cause damage to the rim. To ensure a smooth comfortable ride, wheel balancing is very important.
WHAT CAN I DO TO MAKE SURE MY VEHICLE RIMS STAY IN GOOD CONDITION? Rim and wheel maintenance is an important aspect of keeping your vehicle well serviced. It is recommended by industry experts that the following should be done as a minimum requirement.
ARE THERE DIFFERENT SHAPES OF NUTS?
Yes, there are different shapes of nuts. However, there are three common shapes – Flat, Conical and Spherical. Depending on the type of your wheel, you must use the corresponding shape nut to tighten the wheel on the axle hub to ensure safe and effective centering. The diagram below illustrates the correct type of nut according to the application.
Flat Shape SINGLE Spherical Shape Conical Shape
• Periodically inspect the rim and disc – at the very least during tyre
replacement. There should not be any cracks or deformation visible on the rim.
• Make sure that there is no rust, dirt, lubricant or rubber on the inside of
the rim, especially the seating area.
• Make sure that all wheel nuts are tightened to the torque setting of the
manufacturer. Remember over tightening can be just as dangerous as loose bolts.
• For your own safety, never attempt to repair a damaged rim.
