The global tire market is thriving, and new technologies and trends have the greatest potential for increasing production efficiencies and improving safety and driving comfort in the coming years.
FREMONT, CA: There is a strong future outlook for ongoing expansion in the global tire market. There will be an increase in the demand for tires leading the market to witness steady annual growth across the coming years. This moderate rate of expansion is fueled by healthy if unspectacular trends in economic growth, vehicle production, and replacement demand from various end users. Despite this expansion, the dynamics of global tire supply are changing, with several high-growth opportunities and new technologies helping to forge profit fields in the coming years. One of the most compelling areas for manufacturers is the significant integration of technology into tires, especially for established players seeking to differentiate themselves from newer, cheaper tire suppliers.

Modelling the Magic Triangle
In the space where R&D and manufacturing intersect, the greater use of computer modelling and simulation will accelerate tire development and the introduction of new materials and formulations. Advances in the speed and affordability of computing have started to show benefits in the ability to model and simulate tire design. This includes allowing companies to hone in on a better position within the magic triangle of traction, wear resistance, and fuel efficiency.

One of the most important topics in this area is the thermal modelling of tire performance, which has been overlooked due to the difficulties in simulating tyre heating and its impact on tyre handling at the same time. Another important topic for programmers is to better map the interactions between fillers and elastomers to improve the rolling resistance of new units. As tire labelling and regulations over noise become more prevalent, the industry will look to refine computer models to accurately reproduce these effects virtually.
Making Tires Smart
As automobiles have become increasingly sophisticated in their onboard electronics, there is a growing need to integrate tires into these systems. The primary stage has been to fit tires with radio frequency identification (RFID) chips. The major focus is to shift from the passive information model of a basic RFID system to a dynamic one, with sensors embedded in the tires offering real-time feedback on their performance and road conditions. Adding value through sensors and data capture will be a significant contributor to the future dominance and profitability of premium brand tire makers.
It is estimated that fully autonomous cars will require over 25 onboard sensors each. The use of tire-borne sensors will be pioneered much sooner in the latest generation of automated driving systems. Embedded sensors used in such applications should be strong enough to endure the high temperatures and pressures experienced during tire curing and driving conditions.
