Car tyres are responsible for maintaining balance and keeping the vehicle running on the road. They are the only component that is in contact with the road. They have a crucial role to play in the performance of the vehicle therefore it is essential to have adequate knowledge about them.

Here is everything that you need to know about car tyres, how to maintain them, and how to spot damage, to ensure a pleasant journey on the road.

Tyre Treads

The treads of the tire are marking that begin appearing as the tire begins to wear out. The tread is vital for the grip of the wheel, resistance to aquaplaning, and traction. The depth of the treads can help the motorists determine when it is time to replace the tire. The ideal tread depth is 1.6mm, anything beyond that is dangerous. It can be determined by using a depth gauge that is inexpensive and easy to carry owing to its relatively small size.

Tyre Treads

Motorists can also check the Tread Wear Indicators that appear on the sidewalls of the tire with the letters TWI. It is best to replace the tires if these indicators are smooth with the treads. If the motorists notice uneven wear and tear, it indicates faulty alignment or tire pressure issue.

There is also a variety of tread patterns that serve a different purpose, and it is essential to know which ones are the best tires for cars. Non-directional treads are the most common type that is found among non-high-performance cars. These have continuous grooves across the tire that can move in various ways that add to the convenience of the motorists. Non-directional tires are known for versatility and longevity making them a common choice.

Directional tires have large grooves with v-shaped patterns designed for water drainage that contribute towards the reduction of hydroplaning. The asymmetrical tyres are generally used by sports cars and have multiple patterns. This pattern maximizes the stability and grip of the vehicle on all kinds of terrains including dry and wet roads. The asymmetrical tyres also provide the vehicle the benefit of good cornering owing to their stable grip.

Directional/Asymmetrical tyres give the vehicle the best of both worlds with the v-shaped pattern discharging water and asymmetry allowing great performance on the road.

Knowing Your Tyre Size

The size of the car tire varies with the vehicle and if the motorists are unsure about the size of their car wheels, they can refer to the number around the tires. These numbers help determine the size for example if the number mentioned is 215/60R15, then it means that the section width of the wheel is 215mm, the aspect ratio is 60 and this is the percentage of the tire’s sidewall height compared to the tires section width. The R indicates the construction code, and, in this case, it means that the tire has been manufactured using radial ply construction. Lastly, 15 is the diameter of the rim in inches and it is measured from one side of the wheel flange to the other.

The Age of the Tyre

The motorists need to know the age of the tires so that they can prepare in advance in case they are extremely old. For this purpose, the motorist does not need to look at the sidewall of the tire but the letters ‘DOT’ that is followed by four digits representing week and year. For example, if the number is 2919, then it means that the tire was made in the 29th week of 2019. It is advisable to avoid using a tire that is older than five or six years so that you can get a longer shelf life of the tires.

Repairing a Punctured Tyre

Generally, punctured tires are easily repaired but in case the puncture is through the sidewall of the wheel or the bigger than 6mm, the tire cannot be repaired. Moreover, if the tire is worn out and below the indicator bars, then it cannot be repaired.

Repairing a Punctured Tyre

The punctured tire is turned inside out for repairs by deflating it and removing it from the rim. Then the casing is sealed where the puncture occurred, and the tire is made airtight again. The tire is then refitted to the rim and then placed back on the car.

Using a Spare Tyre for Driving

Spare tire tends to be smaller than the original tire to reduce the load and to make sure that they do not consume a lot of space. They can be used for a short time until the original tire is repaired, but they lack durability and stability, therefore, they are not a long-term solution. If the spare is used for the long-term, they can put a strain on the other wheels and the engine will have to exert to accommodate the mismatched size of the spare.

Using a Spare Tyre for Driving

When the motorist has the spare tire on the car, they must make sure that they drive within 80 km/h as the handling of the vehicle is compromised. Moreover, the spare must be replaced with the regular tire soon.


Having some basic idea about the car wheels and their condition can help the motorists make sure that they keep a close eye and maintain them. A well-maintained tire will deliver an unmatched performance without compromising on the safety of the occupants.
