Many carmakers advise vehicle owners to replace their tires that are more than six years old, but some tire makers insist that certain tires may last up to ten years.

Tire Expiration

According to the Rubber Manufacturers Association, tire expiration is not subject to a particular date, but it depends on several factors. In some cases, these issues will affect both new and used tires in American Fork, Utah. Here are the leading elements that influence the aging process and lifespan of tires.

1. Heat

Over time, any rubber will begin to break down. According to The National Highway Traffic Safety Administration, heat tends to accelerate this process. Tires then degrade faster in warmer climates than in cooler ones. It is no wonder that those exposed to sunlight or coastal climates age faster than those in colder weather conditions. High-speed driving also increases temperature and enhances tire wear.

If you live in a coastal state or an area with warm weather, you should consider retiring your tires earlier. Remember that the effects of tire aging may not always be visibly detectable. Your tires’ integrity may be severely compromised even when a lot of tread remains.

2. Storage

Oxidation in tires happens naturally, whether they are in use, stored as a spare, or waiting on a shop’s shelf. Therefore, all tires age. Still, storage affects the rate of degradation. A tire that is offering service will age more quickly than a tire that is sitting in your garage or waiting in a tire shop. Consider your tire to be in service if you have inflated it and mounted it on a wheel. Also, if you have attached a spare tire underneath your truck, heat, dirt, and harsh weather will hasten its aging.

3. Conditions of Use

How well do you treat your tires? Aggressive cornering, harsh braking, hitting the curb too many times, and other similar poor driving habits increase tire wear. High-speed driving and heavy loading increase stress to tire components. How often you use your car will also affect the rate of tire degradation. Naturally, tires on a vehicle you drive only on weekends will age faster than tires on a car you drive daily. Your tires are also likely to break down faster if they are on hot roadways often.

4. Car Tire Maintenance

Overinflation and underinflation lead to wear. Incorrect wheel alignment causes fast and uneven tire wear. Therefore, to prolong tire life, ensure regular tire rotation, proper inflation, and routine tire inspections. It’s advisable to rotate tires after 5,000 to 8,000 miles. Check the information in your manual and the actual tire when deciding about recommended tire pressure.

Whether you’re buying a new or used tire, you should not gamble with your safety. Understanding what to look for as well as what to avoid in a tire is key to your safety on the road. Know the factors that affect tire longevity to avoid things that can compromise the integrity of your tires and reduce tire life.
