Have you seen that the tyres of vehicles are uneven an have uniform designs on them? These are the grip of the tyres which helps in the generation of friction and therefore helps the vehicle to increase its speed or apply the brake.
Hope it helped you.

Introduction:
Tyres are an essential component of vehicles as they are the only point of contact between the vehicle and the road surface. Over time, due to various factors, tyres tend to wear out and lose their efficiency. Hence, it becomes necessary to change the tyres regularly to ensure safe and efficient driving.

Reasons for regular tyre changes:

1. Tread wear:
The tread on the tyre is responsible for providing traction on the road. As the tyre rotates, the friction between the tread and the road causes the tyre to wear down. Continuous use of the same tyre leads to tread wear, which reduces the grip on the road surface. This can result in poor braking, reduced control, and increased chances of accidents. Therefore, changing tyres regularly helps maintain optimal tread depth and ensures better road grip.

2. Safety:
Worn-out tyres with reduced tread depth are more prone to punctures and blowouts. The tread pattern is designed to channel water away from the tyre's contact patch, providing better wet traction. As the tread wears out, the water dispersal capability decreases, leading to a higher risk of skidding on wet surfaces. Regularly changing tyres ensures that the tread depth is sufficient to maintain safety during various weather conditions.

3. Fuel efficiency:
Tyres with low tread depth or improper inflation tend to increase rolling resistance, resulting in higher fuel consumption. Worn-out tyres also require more effort from the engine to maintain the same speed, leading to increased fuel consumption. By replacing tyres at regular intervals, one can ensure better fuel efficiency, saving both money and the environment.

4. Performance:
Tyres that have been used for an extended period may have reduced performance in terms of handling, cornering, and braking. As the tread wears out, the tyre's ability to provide grip and stability decreases, affecting the vehicle's overall performance. Regularly changing tyres helps maintain the vehicle's optimal performance and ensures a smooth and comfortable ride.

Conclusion:
Regularly changing tyres is crucial for maintaining safety, improving fuel efficiency, and enhancing the performance of the vehicle. By doing so, drivers can ensure better traction, control, and handling, reducing the risk of accidents and improving overall driving experience.
