Next, we will explain why the tuning shop clerk recommends you to install and use Audi A3 wheel spacers. First of all, when you replace a set of aftermarket wheels and tires, but the tires you bought are not exclusively designed to match the Audi A3, you will need to use wheel spacers. Because such tires with high tolerance levels will make them unable to precisely and firmly match the vehicle, you will encounter a series of tire shake problems or even tire fall off in the long-term driving. So, in this case, we would recommend you to use wheel spacers/adaptors to improve the matching degree of tire and vehicle. You can see that in the upgrade installation packages by some auto manufacturers, wheel spacers are also included to improve the safety matching of the vehicle, so don’t worry about using wheel spacers as an alternative approach.
The second point, is when your parts, such as the brake caliper, suspension kit, joint lever, etc., have abnormal friction when the vehicle is going straight or the steering wheel is full, you also need to install wheel spacers to change the backspacing of the wheel to provide more space to allow these parts to operate without interfering with each other. 2022 Audi A3 wheel spacers are installed between the wheel hub and the axle hub to act as an extension of the axle rotor, pushing the wheels and tires out of the rotor. And the functions of the 2022 Audi A3 wheel spacers to vehicle appearance and handling performance I will explain these in my next A3 spacers blog.
