Learn how to determine when to replace a tire on a fleet vehicle, based on the tire tread depth, age, damage, performance, and type.

I have noticed uneven tire wear both on Passenger and Commercial vehicles - If the wear is inside of the tire, it is slightly difficult to notice them. Improper alignment, worn-out suspension and excessive run out are the main causes. This can lead to poor traction and an unsafe ride.

How can you determine when to replace a tire on a fleet vehicle?

Tires are one of the most important components of a fleet vehicle, as they affect safety, performance, fuel efficiency, and maintenance costs. However, knowing when to replace a tire on a fleet vehicle can be challenging, as different factors can influence the tire's lifespan and condition. In this article, you will learn how to determine when to replace a tire on a fleet vehicle, based on the following criteria:

Key takeaways from this article

Monitor tread depth regularly:

Use a tread depth gauge or coin to measure the tire's remaining rubber. Replace tires when they fall below the legal limit or when wear indicators become visible to maintain safety and performance.### *Inspect for tire damage frequently:Look for cuts, cracks, bulges, or uneven wear that compromise tire safety. Address any severe damages immediately by replacing the tire to prevent accidents and ensure optimal vehicle handling.

1 Tire tread depth

The tire tread depth is the measurement of the remaining rubber on the tire's surface, which provides traction and grip on the road. The minimum legal tread depth for most passenger and light truck tires is 2/32 of an inch, but some states may have different requirements. To check the tire tread depth, you can use a tread depth gauge, a coin, or the built-in tread wear indicators on the tire. If the tread depth is below the legal limit, or if the tread wear indicators are visible, you need to replace the tire as soon as possible.

2 Tire age

The tire age is the length of time since the tire was manufactured, which can affect the tire's structural integrity and performance. Tires are made of rubber and other materials that degrade over time, especially when exposed to heat, sunlight, ozone, and chemicals. The recommended tire age limit varies by manufacturer, but most experts suggest replacing tires that are six to ten years old, regardless of their appearance or tread depth. To find out the tire age, you can look for the DOT code on the tire sidewall, which indicates the week and year of production.

3 Tire damage

The tire damage is any physical defect or impairment that affects the tire's functionality or safety. Tire damage can be caused by road hazards, such as nails, glass, potholes, or curbs, or by improper use, such as overloading, underinflating, or misaligning the tires. Some common signs of tire damage are cuts, cracks, bulges, punctures, or uneven wear patterns. Depending on the type and severity of the damage, you may need to repair or replace the tire. However, some damage, such as sidewall bulges or tread separation, cannot be repaired and require immediate replacement.

Uma boa gestão de pneus vai garantir que seja feito uma verificação dos danos com maior frequência, para serem levados para serem recapados, quando o dano for mínimo, ou serem descartados antes de uma falha grave como um estouro. Se a ocorrência de pneus danificados for acentuada e seguir algum padrão de rota/veículo, deve ser verificado o trajeto e o equipamento para apontar as possíveis falhas e evitar o desgaste de futuros pneus pelo um erro estrutural do veículo ou um trecho específico que esteja danificando so pneus.

4 Tire performance

The tire performance is the ability of the tire to handle different driving conditions and demands, such as speed, load, temperature, and terrain. Tire performance can deteriorate over time, due to wear and tear, aging, or damage, which can affect the vehicle's handling, braking, stability, and fuel economy. Some indicators of poor tire performance are reduced traction, increased noise, vibration, or steering pull, or decreased gas mileage. If you notice any of these symptoms, you should inspect the tires and replace them if necessary.

5 Tire type

The tire type is the category of the tire that matches the vehicle's specifications and intended use, such as all-season, winter, summer, or off-road tires. Tire type can influence the tire's lifespan and condition, as different types of tires have different features, advantages, and disadvantages. For example, winter tires have softer rubber and deeper treads that provide better grip and traction on snow and ice, but they also wear faster and perform poorly on dry and warm roads. Therefore, you should choose the right tire type for your vehicle and driving needs, and replace them accordingly.

Knowing when to replace a tire on a fleet vehicle is essential for maintaining the safety, efficiency, and reliability of your fleet. By following these criteria, you can monitor the tire's condition and performance, and make informed decisions about tire replacement. Remember to check the tires regularly, follow the manufacturer's recommendations, and consult a professional if you have any doubts or questions.
