Most vibration-related wheel balance comebacks are due to how wheels get mounted on the balancer. The quality of your ride depends on accurately mounting the wheel on the vehicle hub. Frequently, the tire is blamed as the cause of vibration when in reality, it's was due to improperly mounted wheels. A great rule of thumb is always to back cones with colleagues and utilize a pin plate system for equal pressure.
The hub bore of the wheel must fit onto the vehicle's hub; otherwise, you run into issues due to the wheel being uncentered. Most wheels get mounted with a cone centering them on the balancer's shaft; cones are manufactured with different tapers. The taper and the fit of the cone make a significant difference in accurate centering. Cones having a low taper fit the hub bore and guide the wheel for better centering during the mounting process.
Back cone mounting is a method in which the cone gets mounted from the backside of the wheel; this is often seen to be beneficial for most wheels. After you correctly place your cone on the backside of your wheel, you need to install the pressure cup. You will install the pressure cup and the hub nut on the spindle shaft against the wheel and secure the entire assembly by tightening the hub nut. You can also use a quick nut set instead of the hub nut. Modern balancers use a quick nut that can bypass the shaft threads for faster tightening. Roll the wheel towards you as you tighten the hub nut. This helps the wheel to roll up the taper of the cone as opposed to forcing it to slide up the cone.
Proper wheel balance is the key to a well-aligned tire and the most significant cause of customer callbacks. Follow our diagram below for the appropriate steps on how to mount your wheels.
