Self-Repairing Tyres: Will It Be The Future?

Self-Repairing Tyres: Will It Be The Future? | Isn’t it frustrating to pull off a highway just to fix a flat tyre? Thanks to a major breakthrough in science and technology, we have developed a material that makes it possible for tyres to heal and repair on their own quickly. 

This idea of creating self-healing tyre materials is not new though. Back in 2013, Spanish scientists discovered a material that gained  97% of the original tyre stability back within two hours by just letting it rest after cutting it with a sharp blade. 

But what really is it that makes self-repairing tyres the tyres of the future? Well, we have listed some reasons below for you. 

You don’t need vulcanisation for self-repairing tyres.

An important step in the process of manufacturing this tyre of the future is to make sure that it does not need vulcanisation. In 1839, Charles Goodyear added sulfur to the rubber during vulcanisation. That is when the tyre rubber became more durable and turned into the plastic to elastic state but these links can’t be restored when they break so in no way can these tyres be used for the long run. 

To avoid that, scientists have chemically modified rubber to have the same level of elasticity and durability similar to what can be accomplished by vulcanisation. Within a week, a damaged tyre that is made out of this compound can be used again. The healing period is faster when the heat is added to it as it accelerates the healing process. These self-repairing tyres are able to withstand a stress of 754 pounds per square inch. 

There are standards for self-repairing tyres.

In the past, tyre manufacturers did models of tyres that repair themselves when they’re damaged. Supposedly, these models improve road safety as a punctured tyre can lead to a blowout which decreases car handling dramatically, especially during high-speed rides. However, new discoveries have a different approach to self-repairing tyres. Manufacturers of this type of tyre now use a vicious coat under the tread so when the outer layer gets broken, the mass within it can fill in the holes completely. This may already become a permanent solution for car owners so they won’t have to change their tyres even when they are damaged.

What does the future of self-repairing tyres look like? 

Customers can get self-repairing tyres in the near future. While it’s hard to predict which method and technology can be the most reliable, these innovation secures a slot in the future. Self-repairing tyres will allow riders to drive safer and can prevent a lot of road accidents. From now, it’ll only be a matter of time until this technological advancement becomes a standard in all parts of the world.

Tyre Tip #1: Ignore Legal Tyre Tread Depth

Is Your Road Safety Worth 10 Cents Per Day?

For most of us, the car is part of our everyday lives. Just like our mobile phones, social media, eating, drinking and breathing. You top up and recharge your mobile. You check your social media. You make a list and shop for food and drink. And breathing? Well that’s a good habit that you do naturally.

When was the last time you checked your car? Specifically, your tyres? They are the only thing between you and the road. As you are reading this, can you be certain that your tyre tread depth is legal? Or safe?

What Difference Does Your Tyre Tread Depth Really Make?

Tests carried out by Continental Tyres show that braking distances lengthen faster as your tyre’s tread depth reduces. For example, at 85 kmph on a wet road:

  • The stopping ability of a tyre whose tread depth has reduced from 8mm to 3mm is reduced by 16%
  • The stopping ability of a tyre whose tread depth has reduced from 3mm to 1.6mm is reduced by a further 40%
  • A tyre with 1.6mm tread depth will take more than twice the distance to stop as a tyre with 8mm tread depth

Want to know what this really means?

  • With a tread depth of 3mm, it will take you around 2.5 metres further to stop
  • With a tread depth of 1.6mm, it will take you around 8.8 metres further to stop

Why Is the Legal Tread Depth 1.5mm?

Like most tyre manufacturers and other tyre experts, we recommend that you replace your tyres if your tread depth reduces to 3mm. Given the effect on braking distances, it makes sense. If so many recommend changing tyres at 3mm tread depth, the question is, why is the legal minimum only 1.5mm? It doesn’t make much sense.

70 Cents Per Week – The Cost of Changing Tyres 3mm

Continental Tyres didn’t only test braking distances. They assessed the cost of changing tyres at 3mm instead of 1.6mm. They considered average mileage and that tyres should last around 55,000 to 60,000 kilometres.

Continental has calculated that it would cost the average motorist only 70 cents per week to change tyres at a tread depth of 3mm instead of 1.6mm.

70 Cents Per Week for Safer Driving

Your safety on the road doesn’t only depend on braking distance. Deeper tread depth improves your grip on the road. On wet roads, the tread helps to expel water – and that reduces the risk of aquaplaning. On all roads, the extra grip created by extra tread depth provides better handling and safer cornering.

If you ask yourself one question today – as you check your social media after breakfast – it should be this: Is my life worth 10 cents today? You’ve probably got more than that in loose change in your pocket.
