This is one component of a vehicle that every driver knows is of great importance, but many drivers continue driving on tyres that are too old. It may be easy to continue using old tyres as they may be cheaper and available in plenty, but there are risks that far outweigh any short-term savings. 

Worn tyres can be a hazard to drivers, passengers, and other road users, and they can cause grip loss on the road, a blowout, and much more. The first step to being safe on UK roads is to know why tyre age is important.

Significance of Tyre Age

While most drivers inspect their tyres for obvious defects or wear, far fewer consider just how old their tyres really are. Tyres are constructed of rubber, and rubber products deteriorate over time, even if they appear to be in perfect condition on the exterior. The rubber is dried and cracked by heat, sunlight, and general usage, thus weakening its structure on the inside.

Typically, tyres are recommended for replacement between 5 and 10 years old, even if they still have plenty of tread remaining. A tyre may have a good amount of tread depth but may be extremely hard and fragile on the inside.

Tyres can be aged by referring to the four-digit code stamped on the tyre sidewall. The first two numbers indicate the week of manufacturing, and the last two indicate the year. For example, 1819 signifies that the tyre was manufactured in the 18th week of 2019. Many drivers often don't know that this code even exists, so they may be using tyres that are much older than they think.

The Risk of Blowouts

The greatest risk of driving with worn tyres is a blowout. Rubber loses elasticity and is likely to crack with age. Weaker rubber can fail at any time when under pressure at motorway speed or at high cornering speeds. If a driver's car suffers a blowout at high speed, he or she can lose control of the vehicle in an instant, posing a risk to others on the road at the same time.

As a result of these blowouts from old tyres, they are especially hazardous because they typically don't give any warning beforehand. A blowout occurs in a matter of milliseconds, and a driver's reaction time may not be enough. This is why routine tyre inspections and timely replacements are crucial for ensuring road safety.

Reduced Grip and Longer Stopping Distances

Old tyres also have poor grip, even if they still have a good tread depth. The rubber compounds used in tyre production have a range of ages over which they are flexible and provide grip. After this, the tyre ageing process starts, leading to the rubber's loss of grip on the road. This can be particularly hazardous in wet weather, as it is important to have a good grip to avoid skidding and sliding on water.

Tyres have a direct impact on stopping distances. If a car is equipped with worn or old tyres, it will take much longer to stop in an emergency than a car with fresh, good tyres. When it's a matter of every metre, a good tyre and a bad tyre can be the difference between a near miss and a serious accident.

Cracking and Sidewall Damage

Tyre cracks, especially around the sidewalls and the tread grooves, are a common indicator of tyre ageing. These cracks are often referred to as small surface cracks and are the result of the deterioration of the rubber with age. Although the surface cracks may be minor, they can be a sign of a problem with the tyre's internal structure as well.

Sidewall cracks are a serious problem for tyres as they hold the entire load of the vehicle. Cracked sidewalls are a much more serious issue, as they can lead to serious tyre damage, particularly when driving over potholes or rough road surfaces, which are very common in the UK. Drivers should check their tyres regularly for cracking and should seek expert advice from a specialist in Tyres in Holmes Chapel if they have any concerns.

The Legal and Financial Consequences

Not only is it dangerous, but it's also illegal to drive on unsafe tyres. Tyres in the UK must have a minimum tread depth of 1.6mm over the central 3/4 of the tyre. But just because a tyre has a sufficient tread depth doesn't make it safe. During a roadside check or after an accident, if a tyre is deemed unsafe, there will be a fine of up to £2,500 and three penalty points per tyre. That may result in someone losing their driving licence altogether if they have four unsafe tyres.

Additionally, insurance companies might deny claims if the driver is found to have had worn-out tyres. Old tyres can be a danger to life and can actually result in massive damage to a driver's finances if he or she gets into a collision.

How Often Should Tyres Be Replaced?

As tyre wear will vary with mileage, driving style, and road conditions, there is no single rule that can be applied to all drivers. As a general guideline, however, spare tyres should be examined by a professional at least once a year.

If a tyre has any of the following issues, it's time to replace it: hardening, cracking, or reduced performance. Drivers who travel long distances or those who drive on motorways frequently might require tyres to be replaced more often.

Motor manufacturers and tyre makers are urging drivers to always change tyres older than 10 years, regardless of their condition. The risks just aren't worth it.
