What Are Tread, Tread Depth And Tread Wear In Car Tyres?

You must have seen patterns and designs on car tyres. These patterns of blocks, sipes and grooves are tread patterns. The tread is a common part of car tyres that touches the road surface directly. The role of a tread pattern is vital in the performance and efficiency of car tyres. Tread patterns help the tyres to maintain proper grip on dry and wet roads. If an appropriate tread pattern is absent in the tyres, they would not be able to save car drivers from issues like slush planing, aquaplaning and longer brake distance.

Tyres mainly comes with three common types of tread patterns Symmetrical, Asymmetrical and directional.

Symmetrical tyre:

Tyres with symmetrical tread patterns are very common in passenger vehicles. They have similar designs on both sides of the tread. These tyres deliver directional stability and low rolling resistance. These tyres are effective only on dry surfaces.

Asymmetrical tread pattern:

The asymmetrical tread pattern comes with different designs on both sides. These tyres provide excellent handling and stability in both wet and dry conditions.

Tyres with directional tread patterns come with exceptional ability to run on wet roads. They scatter water efficiently to run more stably on wet roads.

You need four tyres with the same tread pattern. Do not mix your tyres to maintain proper balancing and handling.

What is a tread depth?

As you see, tyre tread is one of the most important components to ensure better stability and performance. Since tyres come with different tread patterns, we have to say that the difference in these designs is vital for changing the behaviour of a car tyre in different driving conditions.

Similarly, car tyres come with different tread depths as well. The tread depth of a tyre also plays a vital role in handling and performance. Tyres with optimum tread depth can scatter snow and water efficiently in wet and snowy road conditions.

Tyre manufacturers make tyres with different tread depths according to driving conditions and driving goals.

Tyre makers cannot make car tyres with too deep or too shallow treads. They always try to make a balance while determining the tread depth for a set of tyres.

For example, winter tyres come with a deeper tread construction whereas summer tyres are available with a shallower tread pattern.

The Minimum Legal Limit Of Tread Depth

According to the rules and regulations, the minimum limit of tread depth in tyres is 1.6mm. It means your tyres have optimum tread depth if they have not hit this limit. It also means that you must change your tyres after they hit this limit because of multiple risk factors.

You should change your bald tyres because you will face legal action if you break the law.

Moreover, bald tyres are not good for your safety.

You may face the following negative results if you drive your car with bald tyres:

Driving with extremely worn tyres is dangerous because of poor grip and traction. Bald tyres may lose control at any moment due to their inefficiency in holding the road surface. Due to poor gripping power, your brakes would not be able to stop your vehicle at the correct distance.

Bald tyres are ineffective in wet road conditions. Their thinner and smooth rubber wall is not able to displace extra rainwater. As a result, they may invite more water to cause hydroplaning.

Bald tyres, due to their thinner tread, are more prone to punctures and blowouts.

Worn tyres generally lose air pressure quickly in comparison with healthy car tyres. Therefore, you must check the inflation level in worn tyres after short intervals.

As you see, bald tyres are risky on roads. Therefore, you must change them when you observe the signs of tread wear.

Treadwear takes place in tyres due to several reasons. If you maintain your tyres and avoid those reasons, you can preserve your tyres for a long time.

Preventive Tips To Slow Down Tread Wear

Save your tyres from heat:

Heat is the most common enemy of your tyres since they are made up of rubber. Rubber is sensitive to heat. Therefore, you must save your tyres from heat, especially during the summer months. However, it is not an easy task because your tyres perform in an open environment. You can try to keep your tyres away from the heat by parking your vehicle in the shelter.

Drive your car slowly:

Driving a car slowly is a good policy to reduce the negative effects of tread wear. More heat and friction take place when you increase the speed of your vehicle. Your tyres are more likely to face degradation due to speed when they run on an uneven road surface. Therefore, consider the texture of the road surface as well.

Measure the tread depth:

Keep an eye on the tread depth. You can easily measure the tread with the help of a 20p coin. Moreover, You can use a tread depth gauge to take measurements as well. Furthermore, you can have an idea about the tread depth with the help of tread wear indicators. These tiny bars are visible only if your tyres are balding.

Check Air Pressure At Regular Intervals:

High air pressure in tyres leads to uneven tread wear in the middle area. Low air pressure is responsible for tread wear on both sides of the tread pattern. As you see, you can save your Tyres Milton Keynes from tread wear if you check the inflation level in tyres at regular intervals.
