Off-the-road (OTR) tire manufacturers are facing many challenges, but also many opportunities with the rise of automation and autonomous vehicles. Harshawardhan Honmode, global head of Yokohama OTR, offers insights on some of these challenges and what lies ahead for the OTR market, particularly in the U.S., which has been growing in importance the last several years.
Question: What are the current challenges faced by OTR tire manufacturers and suppliers?
Honmode: OTR tire manufacturers are facing several challenges in today's rapidly evolving market. One of the biggest challenges is the increasing cost of raw materials, such as natural rubber, steel and oil-based products, which directly affects production costs. At the same time, there is a growing demand for more durable and high-performance tires to meet the needs of industries like mining, and construction that we at Yokohama OTR caters to.
Another challenge is the growing emphasis on sustainability, both in terms of reducing the environmental impact of tire production and developing tires that are more fuel-efficient and have a longer shelf life. Additionally, there is increasing pressure to develop solutions that incorporate advanced technology, such as tire pressure monitoring systems (TPMS) and central tire inflation systems (CTIS), which require significant investment in R&D and technology integration.
Question: How are advancements in automation and autonomous vehicles affecting OTR tire design?
Honmode: Advances in automation and autonomous vehicles are having a significant impact on OTR tire design. Autonomous vehicles, particularly in industries like mining and construction, require tires that can withstand the demands of continuous, high-speed operation, as well as handle heavy loads over longer periods without failure. Autonomous systems also require more precise monitoring and predictive capabilities, which is influencing tire manufacturers to incorporate sensors and smart technologies into tire designs. The push for autonomy in off-highway industries is driving OTR tire manufacturers to innovate faster, integrating smart sensors and automation into tire systems to ensure continuous performance monitoring, predictive maintenance and improved overall efficiency.
Question: How do you see the role of OTR tires evolving with the rise of electric and hybrid off-highway equipment?
Honmode: With the rise of electric and hybrid off-highway equipment, OTR tires are evolving to support the increased torque and weight distribution demands of these machines. Electric vehicles (EVs) generate more torque at lower speeds, which requires tires that offer superior traction and wear resistance. Additionally, the need for enhanced energy efficiency in EVs means that tire manufacturers are focusing on minimizing rolling resistance while maintaining performance. Hybrid and electric machinery also often require more advanced tire designs for better heat dissipation and higher load capacities, which in turn drives innovation in tire materials and structures.
Question: What are the most critical factors in designing OTR tires for mining compared to construction or agriculture?
Honmode: Each sector has unique requirements for tire design. For mining, durability and resistance to punctures, cuts, and heat are paramount due to the harsh conditions and heavy equipment involved. In construction, versatility and a balance of traction, stability, and load-bearing capacity are critical, as these tires often need to perform on a variety of terrains. For agriculture, tires must offer excellent flotation to prevent soil compaction while providing good traction in muddy and uneven conditions.
Question: Can you explain the role of TPMS in OTR tire performance and maintenance?
Honmode: TPMS can play a critical role in maintaining optimal OTR tire performance by ensuring correct tire pressure is consistently monitored. Tires that are under or over-inflated can lead to uneven wear, reduced fuel efficiency, and even risk tire failure. TPMS helps detect issues early and enables operators to adjust pressure before problems arise. This result in better fuel economy, extended tire lifespan and improved safety. TPMS also can help minimize downtime by providing alerts for proactive maintenance, preventing costly repairs or replacements if connected to systems that can send alerts.
Question: What are the best practices for extending the lifespan of OTR tires and how often should they be inspected/rotated?
Honmode: To extend the lifespan of OTR tires, it is crucial to ensure proper tire maintenance, which includes regular inspections, maintaining optimal tire pressure, and ensuring correct alignment and balance. Frequent rotation is necessary to ensure even wear, especially in high-use conditions. There must be timely inspection of tires at least once a month for signs of damage such as cuts, punctures, and wear and tear. Additionally, operators should regularly check tread depth, monitor temperature fluctuations, and avoid overloading vehicles to prevent premature wear. In harsh environments, more inspections that are frequent may be required, particularly for mining and construction applications. Best practices have moved to real time and continuous monitoring of tires to optimise the tire usage.
Question: How is the industry preparing for the integration of artificial intelligence and predictive analytics in OTR tire management?
Honmode: The integration of AI and predictive analytics in OTR tire management is an exciting development. The industry is focusing on using these technologies to predict tire failure before it occurs, optimizing tire performance, and improving maintenance schedules. Predictive analytics can analyze data from sensors and TPMS to identify patterns that indicate wear or potential issues, allowing operators to take preventive action and minimize downtime. AI can also help in designing tires by simulating real-world conditions and evaluating tire performance under various scenarios. AI is also playing a key role in developing materials and compounds for the tires to improve performance.
Question: What strategies can companies use to maximize ROI on their OTR tire investments?
Honmode: Maximizing ROI on OTR tire investments requires a combination of smart purchasing decisions, proactive maintenance, and data-driven tire management. Companies should invest in tires that match the specific needs of their operations, ensuring they are using the right tire for the job. Implementing tire monitoring systems and conducting regular inspections can prevent unexpected failures and extend tire life. Additionally, training operators on proper tire care, such as maintaining correct inflation and avoiding harsh driving conditions, can significantly reduce unnecessary wear. By tracking tire performance data, companies can also optimize tire usage and replace tires at the right time, maximizing their investment.
Question: What safety standards and regulations govern OTR tire usage in the off-highway industry?
Honmode: OTR tires must meet a variety of safety standards and regulations, which can vary by region and application. Some of the key regulations include the International Organization for Standardization (ISO) standards, which govern tire dimensions, load ratings, and performance. Additionally, establishments like European Tire and Rim Technical Organization (ETRTO), Japan Automobile Tyre Manufacturers Association (JATMA) and The American Society for Testing and Materials (ASTM) provide guidelines for tire durability and safety, including tests for puncture resistance and heat resistance. Each country also may have specific regulations around tire marking, load limits and vehicle compatibility. Ensuring compliance with these standards helps mitigate safety risks, particularly in industries like mining and construction where tire failure can have severe consequences.
Question: What advancements are expected in smart tire technology for off highway applications?
Honmode: Smart tire technology for off-highway applications is rapidly evolving. Future advancements include the integration of sensors that monitor tire pressure, temperature, tread wear and load in real time, providing operators with vital data to optimize tire performance and lifespan. We can also expect further development in tire materials and structures, such as self-healing rubber or more energy-efficient compounds.
Additionally, the use of AI and machine learning (ML) will enable predictive maintenance, alerting operators to potential failures before they occur. As the demand for automation increases, smart tires may also integrate with autonomous vehicles, allowing for more precise monitoring and control of tire performance in real-time.
