A proper wheel installation is all about achieving the perfect fit for your vehicle. There are certain techniques that ensure your self-install will involve the necessary safety precautions, so that your car is fully prepared to take on the road. Below you'll find out how to fasten the wheel and hub parts with precision. 1. Check for a flush fit: Before moving forward with mounting the tires to the wheels, make sure that the hub face and wheel fit is flush. You'll be able to do this by installing the wheel to the hub and tightening at least three wheel lug nuts; it's not necessary to tighten to the highest torque value when checking for flush-mating. After verifying that there are no obstructions on the hub that may prevent the wheel from being fastened for a smooth fit, check for clearance with the disc brakes and between the rim and steering modules. 2. Understand your hub: The hub fit is different for some wheels. Typically, there are two types of designs: Lug-centric wheels are centered to the hub through the bolt holes; hub-centric wheels are positioned center to the hub by means of the hub center-to-wheel hub center hole. 3. Measure hole diameters: For many wheels, a hub-centric ring is necessary because the hole diameter is often different from the hub diameter. A centering ring allows wheel manufacturers to use a single center hole size on all wheels, while still functioning with a variety of hubs. If a centering ring is required, this must be installed to the hub before the wheel is placed. When it comes to wheel installation, it is essential to pay attention to detail and thoroughly follow instructions. It can be a long process, but very enjoyable and rewarding if you take pride in caring for your vehicle.
