Why Tyre Age Matters More Than Tread Depth?

Most drivers consider tyre safety by checking first the tread depth. Everybody is talking about that, the legal limit, the penny test and the wear indicators that are stamped into the rubber. However, there is a very important factor that is mostly overlooked, which is tyre age.

The difference between a safe journey and a dangerous journey can be knowing why it is important that tyre age is more important than tread depth. It is not about worrying, but it is about becoming aware of how rubber may evolve with time and why a tyre that may appear good may remain unsafe.

The Hidden Danger of Old Tyres

Tyres are produced using rubber that is in the form of a compound needed to remain pliable and adhere to the road. New Tyres Martin, are very good and provide the grip and handling required in safe driving. But rubber never remains in this condition permanently. 

Tyres do not last longer, whether they are parked in a garage or a car that is hardly used. The rubber gradually becomes hard, less flexible and creates small cracks, which are not necessarily noticeable by human eyes. This process of ageing occurs irrespective of the amount of tread left. 

What Causes Tyres to Age?

There are many factors which can affect your tyres aging. You need to understand these factors so that you can improve the age of your tyres:

Oxygen is the main culprit. The rubber in tyres will react with air and harden with time. The effect is realised when the car is on the road or even at rest.

The ageing is accelerated by sunlight and UV rays. Long-distance tyres are brighter compared to those which were sheltered in garages. UV destroys the chemical bonds of rubber, making it weak.

Change in temperature is important as well. Rubber is affected by heat and cold, expanding and contracting; it internally damages itself and wears out more quickly. This is of particular concern in climates characterised by large ranges in temperature.

Wet conditions may destroy the inner part of the tyre. They can corrode steel belts and detach the rubber. This is a big issue with misplaced tyres or vehicles that are not used frequently.

The Tread Depth Misconception

Most motorists inspect their treads and reckon that the tyres are in order as long as it looks fine. The tread depth is vital in the evacuation of water, and grip during wet weather, and not the entire storey.

A tyre could have been produced a decade ago and covered just a short distance, and it is left with a large tread. Testings Surface-wise, it appears okay, but the rubber has been deteriorating over a decade, and it is possibly hazardous.

On the other hand, a three-year-old tyre that is moderately worn may be safer than a tyre of older years with deep treads. New rubber is not stiff and has better grip, and thus is more dependable.

How to Check Tyre Age?

The age of a tyre does not involve finding a particular measure on the sidewall (as can be done with tread depth, which can be checked either with a simple gauge or a UK coin). Each sidewall of the tyres has a DOT code. The tyre was made in a week and a year, and that number is four digits and is engraved in the middle of the code. 

When Should Tyres Be Replaced Due to Age?

In several safety organisations, it is advised that tyres which are not less than six years of age are changed regardless of the tread depth. Other professionals recommend even a more conservative approach of replacement of tyres at five years in vehicles that are used frequently.

Tyres that are ten years and above are to be changed instantly, even when they are not in use or when their treads are deep. After a decade of usage, the rubber will be worn out such that it will no longer perform.

This is applicable to all Tyres Syston in the vehicle, which includes the spare. Most individuals forget that the spare does not age any less. A decade-old spare, which has not been used, can fail in an emergency when the rubber has fallen out.

Conclusion

The age of tyres is more important than the tread depth. This knowledge assists drivers in making better maintenance decisions. Rather than merely measuring tread depth in the course of MOT, owners are to examine the date of manufacture and schedule replacement.

One should not ignore tread depth. Both age and wear matter. Age has always been a neglected concept, and therefore, when age comes into play, the drivers are caught unawares. The most advisable thing to do is to evaluate age as well as the tread condition before deciding to replace.

Tyre age identification helps to save your life and the lives of other road users, and those of your passengers. The verification is done within a very short period of time, and it can avert major accidents in the future.
