The common way to check a tires expiry date is by analyzing its threads, but is that enough to make a decision about whether you need new tires or not? The answer is no! Research proves that the rubber of the tires goes through wear and tear over time, no matter what the condition of the tread. So this means that even though your treads are good, the rubber elements of the tire may have worn out, making your tires unsafe for the road. Whatever the case, the thumb rule is that an old tire is a safety risk, and should be changed immediately.
On the contrary, for some drivers, old tires may never pose a safety hazard especially those that drive less per year. For example, if you drive 10,000 KMS per year, great chances are that your treads may get worn out over the next 3-4 years, but your rubber will still be in top notch condition. If you drive even less than 10,000 KMS per year, or hardly use your vehicle, old tires may become an issue. This also applies to tires that have never been used at all and spare tires.
Aging tires can be compared to a rubber band, where the cracks on the band when stretch are quite evident. This is the same concept that can be applied to a tire that is used. Cracks may appear inside the tire as well as the surface and tend to develop over time. Even if you do not drive your vehicle, nothing can stop the aging process of rubber and proven theory also applies to high end tires that are made with anti dominant compounds, which simply slows down the aging process but doesn’t stop it.
Rubber, car and tire manufacturers differ in their opinion about tire life expectancy, but automakers recommend that you replace your tires five years after their manufacturing date not the time they were put on your car. Tire manufacturers such as Michelin and Apollo claim that some tires can last up to 10 years, but getting them inspected at regular intervals. Some experts claim that tires age quicker in warmer climates and aging of tires can be faster in coastal climates and when exposed to sunlight
No matter where your spare tires are located, under your vehicle, over your vehicle, in the garage or shop, it is inclined to aging and wear and tear over time. In fact, spare tires are the idlest elements of your vehicle simply because they are hard used and hence get no attention. Like we mentioned before, tires age more in hot areas, which includes the trunk of your car, which is where the spare tire rests in most vehicles.
If you are good to your tires, they will return the favor. This simply means that with regular upkeep and maintenance, tires have the potential to last more than a manufacturers guarantee. Proper maintenance includes regular air pressure checks, balancing, cleaning and rotating the tires. Tires aren’t cheap, and although used tires may be an appealing alternative, they are at most times not worth the investment. When you buy a used tire, you have no clue for the number of kilometers it has been used for, and what its condition was previously. With this in mind, it is best to buy all four tires together from a reputed dealer to ensure you have a safe driving experience.
Of all the parts of your vehicle, your tires are the most important so if your mechanic recommends changing them, then get it done with no further delay.
