Some statistics indicate that a percentage of tires sold in the market are recycled. Is it safe to install them on your truck?
Researchers confirm that many worn-out tires are sold in used tire shops, and it can be difficult for you, and even for a tire expert, to spot signs of internal damage.
When it's time to replace your truck's tires, you face an important decision: do you opt for brand new tires, or consider the budget-friendly option of used tires?
Both options have pros and cons, so making the right decision depends on various factors. Below, we'll explore the differences between new and recycled tires to help you determine the best choice.
Not all used tires are safe; some internal damage isn't visible even to an expert, and a wrong decision could cost you more than you save.
Definition and Manufacturing Process of Recycled Tires
Recycled tires are those no longer suitable for vehicle use due to damage, wear, or reaching the end of their lifespan. They undergo a recycling process to convert them into raw materials or products, rather than being disposed of in landfills or incinerated.
The recycling of used tires aims to reduce the negative environmental impact caused by discarded tire accumulation and to recover valuable resources like rubber, steel, and fibers.
The manufacturing process for recycled truck tires begins with collecting and inspecting scrap tires, then cutting and grinding them into small pieces or rubber powder.
Components like steel and fibers are separated, and the resulting rubber is processed for purification. Generally, recycled tires are not used directly as new truck tires due to safety concerns, but the recycled materials find use in various truck-related applications.
This includes using recycled rubber to manufacture new treads for retreaded truck tires. Shredded rubber is also used in products like rubber road barriers, loading docks, and flooring for shipping areas and truck parking lots.
You should be cautious, as most used tires on the market come from companies that collect old tires and sell them to used tire dealers. These tires are often only superficially inspected for visible defects and air retention, with a minimum tread depth, and sometimes they are even colored to appear new.
Not all used tires are safe; some carry hidden damage that may not be apparent even to an expert.
New vs. Recycled Tires: Quality and Performance Differences
New and recycled tires differ significantly in quality and performance. New tires are manufactured from virgin raw materials using the latest technologies and strict quality standards, ensuring superior and reliable performance across all driving conditions.
New tires offer superior grip, control, and stability in dry, wet, and snowy conditions, thanks to their fresh tread design and full depth. They also boast higher wear resistance, a longer lifespan, and enhanced safety levels in terms of durability and blow-out resistance.
New tires also undergo comprehensive quality testing and come with manufacturer warranties.
In contrast, recycled materials are not used to create entirely new tires for trucks, especially heavy-duty trucks that demand the highest safety standards.
Instead, recycled rubber extracted from used tires serves as a raw material for manufacturing new treads for retreaded tires, or in limited proportions for other non-essential components in new tires, or in various other products like playground flooring and rubber barriers.
While retreaded tires offer an economical and eco-friendly alternative to new tires in some applications—such as commercial trucks, where retreading is common—they do not match new tires in terms of overall performance, durability, and expected service life.
The quality of retreaded tires largely depends on the quality of the original used tire casing and the retreading process itself. Other products made from recycled rubber are designed for different applications that do not require the same high performance and safety standards as new tires.
Therefore, if your priorities are the highest levels of quality, performance, safety, reliability, and a longer service life, then new tires are undeniably the best choice.
While recycled tire materials play an important role in sustainability and waste reduction, finding useful applications in various fields, they are not considered a direct substitute for new tires when it comes to the performance and quality of tires used in trucks, especially in harsh conditions or critical safety applications.
A retreaded tire isn't inherently flawed, but it's not suitable for all conditions or all trucks. Safety always starts with tread quality.
Are recycled tires recommended? And what are their safety standards?
To begin, it's important to clarify that in the case of recycled tires for trucks, the final product is not considered a fully recycled tire. Instead, it is a "retreaded tire" that uses used components, new materials, and recycled materials in limited proportions.
The question then is: Are retreaded tires recommended? For trucks and commercial vehicles, retreaded tires are widely considered an acceptable and sustainable option, provided they meet specific safety standards.
Retreading tires offers several advantages for the trucking industry, including:
Cost Savings
Recycled tires are significantly cheaper than new tires, which reduces operating costs for transport companies.
Environmental Benefits
Tire recycling reduces the amount of waste from discarded tires and consumes less energy and resources compared to manufacturing entirely new tires.
Acceptable Performance in Some Applications
For certain types of trucks and driving conditions, retreaded tires can offer good and acceptable performance, especially on highways and for long distances.
Safety Standards for Retreaded Truck Tires
The retreaded truck tire industry is subject to strict safety standards and regulations to ensure their quality and reliability. These standards include:
- The original casing of the used tire must be meticulously inspected to ensure it is free from any damage or defects before the retreading process begins.
- The new tread used in the retreading process must meet specific quality standards in terms of rubber compound, design, and tread depth.
- The retreading process must be carried out in certified factories that follow standard procedures and specifications to ensure the quality of the retread and the secure adhesion of the new tread to the old casing.
- Retreaded tires must bear clear markings indicating that they are retreaded tires, the retreading date, the company that performed the retreading, and any other information essential for the consumer.
- Ensure that the retreaded tires they use comply with all applicable regulations and safety standards in their operating regions.
Despite the existence of safety standards, retreaded tires are still generally considered to have lower performance and reliability than entirely new tires, but they remain a practical and economical option for many transport companies and commercial trucks operating under routine driving conditions and at moderate speeds.
However, other studies have emphasized that the safety of these tires primarily depends on regular maintenance, such as regularly adjusting tire pressure and ensuring proper wheel alignment.
Furthermore, continuous technological advancements in the tire industry make modern tires, whether new or retreaded, safer and more efficient than tires manufactured in the past.
How to maintain retreaded tires
Maintaining retreaded tires does not fundamentally differ from maintaining new tires. To ensure safe performance and a long lifespan for your retreaded tires, it is essential to follow a regular and consistent maintenance schedule that includes the following aspects:
Weekly or every 10,000-mile inspection of the tire tread
This is because the tire tread is responsible for vehicle stability and its ability to provide effective traction and braking. Therefore, regular inspection helps you detect signs of abnormal wear, damage, or foreign objects lodged in the tire early on.
You can visually inspect by looking for uneven wear, which may indicate alignment or suspension issues, or wear in the center or edges, which suggests incorrect tire pressure, or foreign objects that need to be removed, and any cracks or bulges that require professional inspection.
You can also use a tread depth gauge or a coin to check the remaining depth, and be sure to replace the tire if the depth reaches the legal minimum of 1.6 mm.
Tire Pressure Check
It is advisable to check tire pressure before every trip or at least weekly, to ensure optimal tire performance, safety, and lifespan.
Incorrect tire pressure, whether too low or too high, leads to various issues. These include irregular tread wear (edges wear out when under-inflated, the center when over-inflated), increased fuel consumption due to rolling resistance, degraded vehicle handling, especially during emergency maneuvers, and a higher risk of tire damage and overheating, which could result in a blowout.
Tire Cleanliness
Keeping recycled tires clean is an important preventative measure to extend their lifespan and ensure their safety. This is because the accumulation of dirt, debris, oils, and chemicals on tires can degrade the rubber material and shorten their service life.
Furthermore, cleaning tires allows for a thorough inspection to detect any damage or foreign objects that might be lodged in them. For optimal cleanliness, it's recommended to wash tires regularly using water, mild automotive soap, and a soft brush for the tread and sidewalls.
Smooth Driving
Aggressive driving, which includes sudden acceleration and braking, sharp turns, and high speeds, is a primary cause of tire deterioration and reduced lifespan.
These practices generate excessive heat and stress on the tires, leading to faster tread wear and an increased risk of sudden damage or even a tire blowout.
This is especially important for recycled tires, which may be less capable of withstanding extreme stress compared to new tires.
Avoiding Road Hazards
Driving over sharp curbs, deep potholes, and solid objects on the road damages tires. These hazards can cause immediate tire damage such as cracks, cuts, and bulges, or even invisible internal damage that could lead to future problems.
Recycled tires may be more sensitive to these impacts compared to new tires. Therefore, it's essential to drive cautiously and attentively to avoid road hazards as much as possible, and to minimize driving on rough and unpaved roads that increase tire exposure to damage.
Whether your tire is new or retreaded, the secret to a long lifespan lies in diligent maintenance and attention. Don't neglect tire pressure, and don't wait for the road to surprise you.
Truck Maintenance
Did you know that regular and periodic truck maintenance not only preserves the truck's performance and efficiency but also has a direct impact on tire health, lifespan, and driving safety?!
Experts confirm that mechanical problems in the truck, such as wheel misalignment, damaged suspension, or unbalanced brakes, can cause irregular tire wear, shorten their lifespan, and increase the risk of accidents. Therefore, comprehensive vehicle maintenance is an essential part of tire maintenance.
