What are spare tire cover made of?

When it comes to the construction of a vehicle’s trunk, the often-overlooked component that serves a crucial role in automobiles is the trunk floor board. A trunk floor board is a structural panel that forms the base of a vehicle’s trunk for our belongings. It serves several important functions, including:

  • Providing a level and supportive surface for belongings: The trunk floor board must be strong enough to support the weight of belongings, even when the vehicle is accelerating or braking. It must also be level to prevent items from moving or tipping.
  • Protecting the important parts underneath your car like a shield keeps them safe from dirt, moisture, and even bumps from your belongings.
  • Adding to the car’s overall strength: The trunk floor board makes the car’s body stronger, leading to better handling and performance.

Have you ever wondered what materials are used to create this essential component? In this article, we’ll explore the materials used to make spare tire cover in this era. Let’s explore the three most common options for spare tire cover.

3 Common Trunk Floor Board Materials

1. Automotive Hardboard or Masonite

Automotive hardboard or Masonite manufactured by compressing wood fibers under high heat and pressure. It is a dense, smooth, and relatively stiff material that offers good resistance to moisture and bending. Hardboard is also relatively lightweight and cost-effective, making it a popular choice for spare tire cover.

Features:

  • Lightweight and cost-effective
  • Smooth surface
  • Moisture resistance 
  • Susceptible to dents and scratches
  • Not as durable as plywood or plastic PP

2.Plywood

Plywood is a composite material made by layering and bonding thin sheets of wood veneer. These veneers are peeled from logs using rotary lathes, typically with the grain of each layer running perpendicular to the previous one. The veneers are then stacked in alternating grain directions and bonded with glue. The glued veneer layers are pressed together under heat and pressure to form a plywood panel, which is then trimmed and sanded to achieve the desired dimensions and surface finish. This cross-grain construction provides plywood with exceptional strength and resistance to splitting. While heavier than hardboard, plywood offers superior durability and load-bearing capacity, making it a preferred choice for spare tire cover in newer vehicles.

Features:

  • Exceptional strength
  • Resistant to splitting and warping
  • Heavier than hardboard
  • May absorb moisture if not properly sealed

3. Plastic PP

Plastic PP, also known as Polypropylene, starts as tiny beads called pellets. These pellets are heated and melted, then pushed through a special tool to make long, thin strands. After cooling, these strands become solid pellets or granules. These PP pellets are then melted again in an injection molding machine and injected into a mold to shape a trunk floor board. The board is left to cool and solidify in the mold, then taken out and trimmed to the needed shape. 

The Polypropylene (PP) is a thermoplastic polymer known for its lightweight, impact resistance, and chemical resistance. It is also recyclable, making it an environmentally friendly option for spare tire cover. Plastic PP spare tire cover are becoming increasingly common in modern vehicles due to their weight-saving advantages and resistance to corrosion and moisture damage.

Feature:

  • Lightweight and impact resistant
  • Chemically resistant and corrosion-resistant
  • Recyclable and environmentally friendly
  • Can be more expensive than hardboard or plywood

in conclusion, spare tire cover are typically made of automotive hardboard, masonite, plywood, or plastic. The choice of material for a trunk floor board will depend on the specific needs of the vehicle. For example, a vehicle that is designed for heavy-duty use will need a trunk floor board made of a durable material. A vehicle that is designed for fuel economy may use a trunk floor board made of a lightweight material. Ultimately, the selection of trunk floor board material reflects the specific needs and priorities of vehicle manufacturers and consumers.
