The spare tire cover is also called trunk cover or luggage board. Laying in the trunk, it has 3 important tasks:
- It is the isolation between spare tires and the trunk. So the size of this panel has to be large enough.
- It is a part of the trunk storage. So the cover panel should be strong enough.
- It is listed in the NVH system. The trunk cover panel is supposed to reduce the noise from the chassis and rear wheels.
