The lifespan of tires is one of the most crucial aspects for a truck; in fact, tires represent a vast world of advanced technologies that work in conjunction with other truck systems, providing smooth driving, flexible cornering, and the ability to stop at the right moment. All these features operate at their full efficiency and original quality only during the tire's initial lifespan. After years and thousands of kilometers, a tire becomes more of a hindrance than a useful component. For this reason, Darbk Company strives to raise awareness about the importance of replacing tires at the scheduled time and maintaining them for as long as possible to avoid complex, uncontrollable problems.
In this guide, we'll show you how to determine the lifespan of tires, the factors that increase or decrease tire life, and highlight the signs indicating that a tire has reached the end of its service life. We'll also guide you on how to maintain new tires for their maximum possible lifespan. Certainly, there are many details about tire lifespan, which we've covered in detail in the comprehensive guide to understanding tire lifespan.
What do we mean by tire lifespan?
Tire lifespan can be understood by examining their internal composition, which involves combining rubber with solid materials, carbon, and other essential composite materials. All these components have an expiration date and degrade after a certain period, especially when exposed to air, sun, and heat. Therefore, manufacturers provide an approximate lifespan during which a tire will remain functional, provided it does not exceed this duration.[SEG 7]Generally, the lifespan of tires ranges from 6 to 10 years, depending on the tire type and usage conditions. Certainly, various factors can positively or negatively impact tire life, such as climatic conditions, driving style, and other technical truck issues. Let's briefly discuss the factors that affect a tire's lifespan:
First: Tire Type
By types, we mean classifications based on seasons and environments, such as summer tires, winter tires, mud tires, and other varieties. These classifications are not arbitrary; each type has specific characteristics. For instance, summer tires are better at withstanding heat but perform poorly in low temperatures and icy conditions, and vice versa. Tires designed for rainy areas and muddy environments have treads engineered to disperse obstacles and increase road grip. Therefore, drivers should identify their commercial activities and choose tires appropriate for those activities to avoid using tires not suited for the environment they operate in, which would lead to a shorter tire life and rapid wear.
Second: Driver's Driving Style
A driver's truck operating style is one of the most significant factors affecting tire longevity. Driving at speeds exceeding the tire's rated limit and sudden braking unnaturally increases pressure on the tires, leading to damage to specific parts like the edges and grooves. Consequently, the tire's lifespan is significantly reduced. Conversely, smooth driving on appropriate roads can greatly extend tire life by slowing down uneven wear and groove damage. Therefore, drivers should consider this, given its substantial economic impact and the risks it poses to truck and tire safety.
Third: Climatic Conditions
Heat and humidity play a significant role in tire lifespan. High temperatures directly affect tire expansion and road adhesion, significantly increasing tire wear compared to tires operating in moderate temperatures. Conversely, operating tires in cold regions causes the rubber components, both internal and external, to harden, leading to cracks. In humid and wet environments, the internal structure of the tires is the first to be affected by extensive water exposure, resulting in rapid tire degradation.
Fourth: Balance and Air Pressure
Improper balance can lead to high levels of wear and affect the truck's stability on highways. Following this, air pressure has a critical impact on tires. Incorrect pressure can cause tread damage and sudden tire blowouts. Experts therefore recommend regularly checking air pressure and balancing tires every six months or 10,000 kilometers, or according to the tire and truck manufacturer's recommendations, to ensure even weight distribution across the tire surface.
Fifth: Overloading
Some drivers exceed designated load limits, significantly increasing the risk to lives and property. Every truck has a specific load capacity and weight it can bear, which should never be exceeded. Similarly, tires also have limits, which you can find by reading their specifications, indicating the maximum load for a single tire or a pair. To achieve the full lifespan of your tires without sudden damage or frequent maintenance, you must adhere to the weight of the load you are transporting and not exceed the specified limit, as this is illegal and can result in financial penalties and license suspension.
Methods for Calculating Tire Lifespan
How do you determine the lifespan of tires? And how can we know the remaining life of tires and their operational capacity? These questions and more will be answered in the following sections:
Reading the Serial Number (DOT Code) and Manufacturing Date
- : Most tires have a (DOT Code) written on their sidewall. This code includes numbers indicating the week and year of manufacture. You can understand this through the following example: (4319). The code here is divided into two parts, with each pair of numbers separate. So, 43 represents the week, and 19 represents the year. This tire was produced in the 43rd week of 2019. This way, you can easily determine the manufacturing date and assess the tires' condition and their suitability for continued use. However, if tires are more than five years old, it is strongly advised not to use them at all, even if they appear to be in good condition.
- Inspecting Tread Depth and Thickness:Tread depth and tire thickness are among the most crucial indicators of a tire's age and its suitability for road use. Using depth measurement tools, you can determine if the depth is sufficient. If the tread depth is less than 1.6 mm, the tire has entered a critical stage, and driving on it becomes unsafe, failing to meet general safety standards and specifications in Saudi Arabia and globally. This is because it won't provide adequate traction, reducing the necessary friction on the road, which can lead to the truck skidding, tire blowouts, or even more severe accidents.
- Inspecting for Cracks and Bulges: This is one of the easiest inspections, a simple visual check performed by examining the tire's circumference from the outside and inside (using a mirror) to identify cracks or detect abnormal bulges. The appearance of bulges on tires indicates internal damage, and cracks suggest that the tires have reached the end of their lifespan and must be replaced immediately.
Impact of Tire Age on Truck Performance
In trucks and large vehicles, performance is non-negotiable, not only for safety but also to avoid excessive fuel consumption and damage to internal engine components, which can lead to delays in completing tasks efficiently. With worn-out tires or those used for several years, the chances of achieving optimal performance are very low and unexpected. You will encounter numerous problems with traction and pulling capability, as well as instability and poor road holding. Tires often lose their flexibility after prolonged use, especially if not properly maintained. Below, we will explore the noticeable effects on the performance of trucks running on worn-out tires.
1- Impact of Tire Age on Traction and Stability
The relationship between tire age and its ability to provide traction and stability is distinctly inverse: the older the tires, the less traction they offer, and the harder it becomes to maintain stability on the road. The cornerstone of this relationship is the tread, the part that directly contacts the road. The deeper the tread, the greater the truck's ability to maintain traction and stability, navigate bumps, and grip the asphalt, especially in rainy, wet, or muddy conditions, or in construction and excavation areas. If the tread thickness decreases and it becomes worn, the truck will struggle to stay stable on the road, and the engine load will increase, in addition to the danger of a sudden tire blowout without warning.
One sign that the tread has worn down is a decrease in the tire's effectiveness at displacing water while driving on wet roads, which increases the risk of skidding on watery surfaces, also known as (Hydroplaning), leading to a complete loss of control over the truck and a horrific accident.
3- Impact of Tire Age and Loss of Flexibility on Truck Performance
Truck tires are made from rubber materials reinforced with other strengthening agents, which gives the rubber suitable flexibility and strength to withstand pressure, heat, and friction. As tires age, these materials gradually begin to dry out and break down, losing much of their flexibility due to exposure to heat, UV radiation, and various weather conditions—from low temperatures at night and early morning to extreme highs in the middle of the day. This subjects the tire to the most rigorous operational tests, and all of this leads to two dangerous outcomes:
- Increased Tears and Cracks: Older tires are more prone to sidewall cracks, which increases the likelihood of a sudden blowout, especially under high pressure or heavy loads.
- Reduced flexibility = lower performance: The truck becomes less smooth to drive, and cabin vibrations increase, affecting driver comfort and their ability to control the truck on unstable roads and at high speeds.
3- The Impact of Tire Age on Fuel Consumption
Old and worn-out tires, especially those that have lost a significant portion of their tread or are improperly inflated, increase rolling resistance. This refers to the effort required to move the tires on the road, leading to a noticeable increase in fuel consumption. The truck needs additional energy to maintain speed and acceleration continuously, which negatively impacts drivers in terms of:
Economic Impact: With rising fuel prices worldwide, worn-out tires force higher fuel consumption, leading to a deficit in the budget of the truck driver or logistics company. This cost multiplies as problems increase across the entire logistics fleet.
Technical Impact: When rolling resistance increases, the load on all truck components, from the suspension system to the gear shifter, becomes greater. This all puts a strain on
4- The Impact of Tire Age on Blowouts
Old tires that have been in use for two years or more are typically more prone to blowouts, especially if the truck is heavy and carrying high loads. This occurs because the rubber materials lose their elasticity and ability to withstand pressure and tension. Additionally, cracks form on the tire surface, creating weak spots where pressure concentrates, leading to a dangerous explosion that can cause significant financial losses and casualties. Therefore, truck drivers must inspect their tires daily before any trip to ensure safety and confirm there are no major issues that could affect the journey or result in an uncontrollable blowout.
5- The Impact of Tire Age on Load Distribution
Trucks are manufactured to carry heavy loads and transport large, weighty materials from one place to another. This requires balanced load distribution across the entire truck and the total weight distributed evenly among all tires to achieve the necessary stability for the truck to operate normally without catastrophic accidents such as rollovers, cargo spills, or even damage or fracturing of the truck's main chassis. Tires play the most crucial role in this process through equal air pressure and uniform tread depth across all truck tires. Here, tire age plays a vital role, as old tires struggle to maintain balanced tread and a wear rate consistent with the other tires. This causes an imbalance in the truck and increases pressure on the older tire, leading to a loss of smooth driving and high maneuverability due to the tire's inability to perform its duties optimally. Therefore, old tires must be replaced with new ones that have a consistent wear level with all other truck tires.
Ways to Significantly Extend Tire Life
There are many methods and tricks to maintain tires for as long as possible or even extend their lifespan. Of course, this can be effective with good, excellent tires. If you're looking to save time and effort, you're in the right place, as Darbk Saudi Company's tires are designed for longevity and specifically tailored for the environment of Saudi Arabia, the Gulf countries, and the region. They are equipped with the best technologies drivers need, in addition to the warranty and high quality that we at Darbk Company pride ourselves on.
Firstly: Regular Rotation: Tire rotation can be defined as moving front tires to the rear and rear tires to the front, or symmetrical rotation. Drivers perform this procedure to ensure even wear across all tires, preventing issues that could damage a single tire. Experts recommend rotating tires every 10,000 kilometers. You can also rotate them with every engine oil change, which helps ensure greater adherence to regular tire rotation.
Secondly: Regular Tire Inspection: This point might seem unimportant, but it is one of the most crucial steps to ensure a longer tire lifespan. Regular inspection protects you from sudden hazards and reveals faults or damage as soon as they occur. This allows you to address and fix the issue before it's too late and the problem escalates daily without your knowledge.
Thirdly: Suspension System Inspection: Tires are directly linked to the suspension system and anti-skid system, which work together to regulate tire rotation naturally. If there's a problem with either of these, it often causes tire damage and increases wear, leading to a shorter tire lifespan and numerous unpredictable issues, potentially even increasing the load on the engine.
