Tyre technologies
Efficient and well-maintained tyres can reduce emissions, improve durability, and reduce noise pollution. Tyres contribute to 20%-30% of vehicle fuel consumption and 24% of CO2 emissions.
Advances in technology and design has increased the efficiency of tyres by low rolling resistance with specialised tread designs, materials, and construction techniques. Leading companies are heavily invested in R&D, for example printing of airless tyres using 3D technology. Manufacturers also use carbon black, silica, and other chemical compounds to improve the durability and strength of tyres. To reduce the tyres' friction and weight, they also use natural rubber made from dandelions, silicate from the ash of rice husks, and vegetable oils and resins. Bamboo and some reusable materials are also in use.

How it works
- Rolling resistance of tyres is crucial to fuel efficiency and emissions. 30%-35% of rolling resistance is associated with tyre tread.
- By changing the tread compounds, rolling resistance can be reduced and improve the efficiency of a drive up to 30%-40%
- In addition to treadwear, wheels, tyre size, and proper inflation also play an important role.
Typical use case:
Run-flat tyres for luxury vehicles, low-rolling-resistance tyres for hybrid and electric vehicles, winter tyres for driving on snow and ice, high-performance tyres for sports cars, and all-terrain tyres for off-road vehicles.
Implications for operations:
Weather, road conditions, and compatibility issues can impact vehicle performance. Proper consideration to specific needs of the vehicle, ratings, consulting with a professional, and following proper maintenance and safety guidelines can help to avoid many of these issues.
