Types of Discarded Tires

Discarded tires are a significant environmental concern, given their large volume and the challenges associated with their disposal. However, they can be repurposed into a variety of valuable products. Here are some common types of discarded tires and their uses:

• Passenger Car Tires

  Passenger car tires are those used in standard vehicles and are the most common type of tire. When discarded, they can be reused as asphalt rubber, which adds elasticity and durability to roads. They can also be used in sports surfaces, providing cushioning and traction in tracks and fields.

• Truck Tires

  Truck tires are larger and more robust, making them suitable for heavy-duty applications. Discarded truck tires are often retreaded for continued use in commercial trucking. Retreading is a cost-effective and environmentally friendly practice that extends the life of the tire. Additionally, the steel belts from truck tires can be recycled into steel reinforcement for concrete.

• Off-Road Tires

  Off-road tires are designed for vehicles such as trucks and ATVs. When these tires are discarded, they can be ground into tire-derived fuel (TDF). TDF is used in cement kilns and paper mills, providing a high-energy content fuel source. The rubber from off-road tires can also be recycled into rubber mulch for landscaping and playgrounds, offering a durable and low-maintenance ground cover.

• Motorcycle Tires

  Motorcycle tires are smaller but still contain valuable materials upon disposal. Discarded motorcycle tires can be repurposed into noise barriers, reducing sound pollution along highways. Their unique rubber composition also makes them suitable for the production of rubber mats, providing anti-slip surfaces for various industrial and commercial applications.

• Bus Tires

  Bus tires are similar to truck tires in size and composition. Discarded bus tires can be used in civil engineering projects, such as embankments and sound barriers, due to their lightweight and filling properties. The fibers and steel components of bus tires can be separated and recycled into various materials, contributing to a circular economy.

Specifications and Maintenance of Discarded Tires

Many manufacturers and suppliers offer only discarded tires that meet specific standards. Here are some of the key specifications:

• Size and dimensions

  Discarded tires are available in various sizes and dimensions to cater to different vehicles and equipment. This includes aspect ratio, width and rim diameter.

• Tread depth and pattern

  Tread depth is an important specification when it comes to discarded tires. This is because it determines traction and tire performance. Discared tires also come with different patterns designed to enhance on-road or off-road traction.

• Load capacity

  Each discarded tire comes with a load rating for commercial truck tires that indicates the maximum load it can support. The load rating is an important consideration when choosing a suitable tire for specific vehicle requirements.

• Speed rating

  The speed rating of a discarded tire indicates its maximum speed capability. The specification is important for high-performance vehicles and also ensures tire stability and safety at high speeds.

• Tire construction

  Tire construction refers to the internal structure and material of the tire. This includes steel belts, polyester cords and nylon overlays. Each construction component plays a role in determining tire strength, durability and performance.

• Tire compounds

  Discarded tires are made from different tire compounds. This is because tire compounds affect traction, durability and tire performance in different weather conditions.

Maintaining discarded tires is vital in ensuring safety, performance and durability of the tires. Here are some basic maintenance tips:

• Visual inspection

  Users should conduct regular visual inspections of the tires. This is to check for signs of damage, wear and punctures. Early identification of such problems can help with timely repairs.

• Proper inflation

  Proper tire inflation is essential in maintaining the shape of the tire and even tread wear. Users should check tire pressure at least once a month and before long trips to avoid overinflation and underinflation problems.

• Tread depth monitoring

  Users should regularly monitor tread depth using a tread depth gauge. This helps maintain traction and tire performance, especially in wet and slippery conditions.

• Regular rotation

  Tires should be rotated regularly to enhance even wear and tire life. Rotating the tires also helps with optimal performance and traction.

• Storage conditions

  When not in use, discarded tires should be stored in dry and shady places, away from sunlight and moisture. This helps maintain the quality of the rubber and tire life.

How to choose discarded tires

Because of their distinctness, various types of tires suit different purposes. When purchasing tires, it is essential to understand the needs and requirements of the customers. Here are some factors to consider when choosing tires for resale.

• Weather conditions

  Weather conditions play a vital role in the type of tires to choose from. There are three main types of tires suitable for different weather conditions. For instance, all-season tires are ideal for areas with moderate weather conditions. They offer versatility and good performance in wet and dry conditions. On the other hand, summer tires are suitable for high-performance vehicles in warm climates. They offer good grip and handling on the road, while winter tires are ideal for icy and snowy roads.

• Size and vehicle type

  Tires come in different sizes. Therefore, it is important to choose the right size for the vehicle. The size of the tire is indicated on the sidewall. It is measured by the width, aspect ratio, and diameter. For instance, a tire with a size 225/50R17 has 225mm width, 50mm aspect ratio, and 17-inch diameter. Additionally, when choosing tires, consider the type of vehicle. Different vehicles have different tires; for instance, SUVs and trucks have larger and more durable tires.

• Tread pattern

  Tread patterns are also essential when selecting tires. They affect the tire's performance, handling, and traction. Identifying the type of tread pattern suitable for the specific needs of the customers is crucial. There are three common types of tread patterns; symmetrical, asymmetrical, and directional. Symmetrical tread patterns offer even wear and good performance on dry and wet roads. Asymmetrical tread patterns combine the two patterns, which gives good traction on dry and wet roads. Finally, directional patterns provide good grip and traction on wet surfaces.

How to DIY and Replace Discarded Tire

Any serious DIYer will find it easy to recycle tires at home. It is much easier to repurpose the tires before they get discarded. Following the proper steps when tires are still on the vehicle makes the process easier.

• Removing the Tire from the Wheel Rim

  Deflate the tire completely and break the bead that seals the tire to the rim using a bead breaker or a pry bar and a strong board. Next, use tire irons or spoons to leverage the tire off the rim, working around the circumference to loosen it from the rim.

• Cutting the Tire Apart

  Cutting a discarded tire into pieces makes it easier to work with. Use a reciprocating saw or angle grinder with a metal-cutting blade to cut the tire into smaller sections. This also makes it easier to remove the steel belts and other reinforcing materials found inside the tire. Protective gear such as gloves, goggles, and a dust mask should be worn when cutting the tire.

• Removing the Steel Belts and Fabric Layers

  Pull out the fabric layers and steel belts from the tire sections using pliers or a tire iron. These materials can be recycled, but the recycling process is different depending on local regulations.

• Shredding the Tire Rubber

  Shredding the rubber makes it easier to transport and recycle. This can be done using a tire shredder, which is a specialized tool designed to cut tire rubber into small pieces. Tire shredders are also used in some recycling companies. They are not so common in most households, so this step might be skipped if one does not have a tire shredder.
