Wheel Spacers Are Used for Various Reasons
- Bigger Tires: when you need to install larger tires, in order to avoid friction between the tires and the suspension and liner, additional backspacing is required, you can choose to buy a set of negative offset rims or wheel spacers, but it is clear that wheel spacers look more straightforward and more economical;
- Enhance Traction: the increase in track means an improved lateral grip, a more comfortable ride, and an extra track makes the car more stable at high speeds;
- Bigger Caliper: High-performance brake kits often require more space for installation, and customers often do not consider the need to purchase another set of suitable aftermarket rims after modifying the high-performance brake kit, then the easiest way is to place wheel spacers between the wheel and hub assembly, providing additional space to allow the brake kit to run…
Hub-centric Design Wheel Spacers ：
Are hub-centric wheel spacers safe? Why do you need hub-centric wheel spacers when mounting aftermarket wheels? Before we figure it out, let’s get to know the difference between hub-centric and lug-centric wheels first.
Hub Centric Wheels VS Lug Centric Wheels
Hub-centric wheels refer to the wheels which are centered by the hub assembly. Nearly all factory wheels are hub-centric. They are made to suit a certain vehicle or range of vehicles. The center bore size of these OEM wheels is engineered to fits snugly against the original hub assembly. This offers the most accurate way to center the wheel and the hub assembly. In a hub-centric design, it is the wheel-to-axle connection that undertakes the weight of the car as well as bears the forces acting on the wheel. And the lug studs/nuts are used to fasten the wheel to the mounting plate. This form allows better resistance of impact loads from being created when motoring on typical roads.
Lug-centric wheels refer to the wheels which are centered by the lug studs. Most aftermarket wheels are lug-centric design because this allows manufacturers to make larger center bore diameter wheels that can fit a wider range of vehicles without having a specific axle shape for a hub. Due to the larger center diameter of the wheel, there is a certain gap between the axle and the hub, which means that the wheel is centered by the lug studs rather than by the hub assembly. Without firm contact, and lacking the hub’s support, the studs play the role of bearing the road impacts. Some fierce impacts are strong enough to deform the studs, making the wheel no longer concentric with the hub, resulting in vibrations. In this instance, if the lugs suffer fatigue failure, the wheel will come off the vehicle, leading to an accident.
Hub Centric Wheel Spacers
Hub-centric wheel spacers mean wheel spacers with small rings of metal made with specific diameters to fit the wheel hub, transforming a lug-centric wheel into a hub-centric one. They are designed to make a snug connection between the wheel and hub assembly, ensuring the hub carries the weight of the car instead of the studs or bolts. This allows the wheels are truly central to the vehicle hub, meaning no high-speed vibrations through the wheels. Meanwhile, hub-centric wheel spacers also reduce the stress on the wheel studs or bolts, improving the service life range.
Advantages of Hub-centric Wheel Spacers:
1. Hub-centric wheel spacers create the wheel-to-axle connection, acting as a role of transferring studs/bolt loads to the hub.
2. Hub-centric wheel spacers can help eliminate high-speed vibration by filling the gap between the aftermarket wheel and the hub assembly.
3. By custom data, hub-centric wheel spacers make it possible to install aftermarket wheels with different center diameters.
4. Higher precision hub-centric wheel spacers can help the fit between the parts, and the friction generated by the contact surface can help the parts to be fixed.
Some aftermarket wheel manufacturers claim that all of their wheels are hub-centric. As a matter of fact, they equip the wheels with proper hub-centric wheel spacers instead of custom-make the wheels of your vehicle hub diameters. Truly, hub-centric wheel spacers are around as important for aftermarket wheels as wheel bolts/nuts are. And for safety and quality, purchasing from a professional manufacturer is trustable and cost-effective. For correcting wrong ET/offset, hub-centric wheel spacers are necessary equipment. Don’t be underestimated that buying some low-quality wheel spacers at a low price. It is for your driving experience, furthermore, for your life safety.
