Burleigh Heads Tyre Expert Discusses Wheel Nut Retourquing

Nuts about wheel nuts: Retourquing wheel nuts

Torque is basically the unit of measurement for the twisting force that’s applied to a wheel nut. Wheel nuts are torqued for each wheel by mechanics to ensure that they meet the vehicle manufacturer’s standards when fitting the wheel for the first time. However, a second check-up is also necessary.

Chris Lett, Australian tyre recycler and owner of Branigans Tyres gives vehicle owners a lesson on retourquing wheel nuts.

When new, or substituted wheels are fitted for the first time, the individual responsible must torque all wheel nuts according to the vehicle manufacturers’ specifications as seen in the vehicle owner’s handbook and vehicle documentation. “After 50 kilometres of driving on the new tyres, wheel nuts must be checked once again, and if needed, be retourqued to restore initial value,” says Lett.

Each vehicle make will be subjected to different amounts of torque to tighten up the wheel nuts, as well as to avoid causing any damage in the process.

“In terms of the correct order for wheel nut torquing, loosening or tightening wheel nuts properly, requires a particular tool known as a tool wrench,” says Lett. “The vehicle owner, or mechanic will start by setting the torque wrench to half of the expected torque, tightening each nut according to that setting,” Lett adds.

The setting is then adjusted on the wrench to tighten all the wheel nuts to the correct torque. Wheel nuts are tightened in a particular sequence to allow thorough torque. The proper order for any wheel with five or ten nuts is a star-shaped pattern. A wheel with four wheel nuts, on the other hand, is tightened in the shape of a cross.

Should wheel nuts be placed too tightly, they can cause intense issues such as wheel stud stretching, as well as fastener threads being stripped. Brake drums can also become warped, along with the wheel hubs. If wheel nuts are placed loosely, they can lead to wheels potentially coming off while driving. Therefore, it is important to find the right balance when torquing the wheel nuts.

Dirt, sand and rust between the threads of a nut can create false torques during the first fitting, where the force applied, outdoes the friction, but does not result in a clamping force. It is important to take note of this and keep a close eye on all wheel nuts to ensure they’re well maintained and solidly torqued.

Wheel nuts sustain strains and stresses during daily road use, so regular wheel nut retourquing should be conducted to ensure the strength, quality and safety standards are reaffirmed. Wheel nut retourquing is a priority that must be attended to every year.
