HOW TO PREVENT THE WHEEL STUDS/NUTS TO COME LOOSE

1. Correct bolts (length, kon/ball)
2. Dry and clean grooves
3. Clean contact surfaces
4. Clean contact sufaces for bolts
5. Right tightening torque
6. After tightening

ALSO WHORT THINKING ABOUT

• Check to make sure thewheel is designed for the vehicle on which it will be fitted. If the wheel is different in type to the vehicle’s original wheel, you must check to make sure that the relevant legal requirements are complied with. Check to make sure the rim matches the tyre which will be fitted on to it.
• Check to make sure the wheels are not damaged (deformation, dents, or cracks). The rim base must be clean and free from all traces of rust. A well-cleaned rim will facilitate correct balancing.
• Wheel studs/nuts should be tightened crosswise to the torque prescribed by the vehicle manufacturer.
• After driving for about 100-200 km, you should check the tightening of the studs/nuts, and if necessary you should after-tighten them.
• You should also check the tightening torque at least once a year, and after-tighten if necessary.
• Installation of alloy wheels sometimes means that the vehicle’s original wheel bolts cannot be used. Therefore, always check carefully that the correct wheel bolt / nut is used, so that a satisfactory fastening is obtained. Always bring original wheel bolts / nuts if a change to spare wheels should be necessary.
