As the automotive industry shifts toward sustainability, electric vehicles (EVs) are becoming increasingly prevalent in commercial fleets. This transition highlights the importance of reevaluating the components that ensure your vehicle's efficiency, safety, and longevity—specifically, the tires. For business owners and fleet managers who already use commercial EVs or are considering fleet electrification, comprehending the nuances of EV tire design and selection is indispensable.

Understanding the Challenges

Commercial electric vehicles have demands that differ significantly from those of their internal combustion counterparts. The immediate torque delivery and heavier weight due to large battery packs put additional stress on the tires, which can lead to premature wear and tear.

These characteristics necessitate tires that can withstand additional load and minimize rolling resistance, contributing to the vehicle's overall range and efficiency.

Additionally, the silence of electric motors amplifies road noise, making tire noise a crucial factor for operator comfort—a vital consideration for vehicles in continuous operation, such as buses and long-distance delivery trucks/vans.

Selecting EV Tires for Durability, Performance, and Noise Reduction

When selecting tires for your commercial electric fleet, it is crucial to prioritize durability, performance, and noise reduction. Fortunately, tire manufacturers are incorporating emerging technologies to develop tires specifically designed for electric vehicles.

Durability: The construction must be robust enough to handle the extra weight of EVs without compromising performance. These tires feature reinforced sidewalls that improve rigidity when cornering and advanced materials engineered to manage the high torque output typical of electric motors.

Performance: Tires with low rolling resistance are an increasingly important technological advancement. Manufacturers are developing new materials that reduce the energy loss as tires roll, enhancing the vehicle’s range between charges.

Noise reduction: Innovations in tire technology, such as improved tread designs, rubber compounds, and foam baffles, are emerging to help reduce road noise. These advances are crucial for enhancing driver comfort and reducing noise pollution in urban environments. Road noise from tires in an ICE vehicle is usually masked or drowned out by the sound of the engine. Not so with an EV.

Tire Manufacturers are Rising to the Challenge

The inexorable rise in EV adoption has not gone unnoticed by tire manufacturers that recognize the unique needs of commercial EVs.

For example, Goodyear has introduced several innovations tailored specifically for commercial electric vehicles (EVs) to improve performance, efficiency, and durability. These innovations are showcased in Goodyear’s  RangeMax RSD EV tire. Engineered to offer lower rolling resistance than standard tires, this tire enhances energy efficiency across all types of drivetrains, while also being designed to handle the higher load capacities typical for electric vehicles, thus delivering better range and durability.

Michelin is also introducing technological advancements in the commercial EV tire sector with offerings like the MICHELIN X® INCITY™ Z / EV Z tires. These tires are specifically designed for electric buses, but optimize performance across traditional buses as well. Key features include improvements in load capacity (up to 8 tons), reduced rolling resistance (up to -13%), and enhanced mileage (up to +10%).

Furthermore, some tire manufacturers are integrating sensors that monitor conditions such as tire pressure, temperature, and tread wear in real-time. These smart tires can significantly contribute to safety and maintenance scheduling, ensuring that the tires are always in optimal condition and thereby reducing maintenance downtime.

According to Continental, advanced tire sensor systems can extend tire life by 4,660 miles, improve fuel mileage by up to .6%, and reduce fuel consumption by as much as 3%.

Impact on Total Cost of Ownership

Investing in high-tech, EV-specific tires may come with a higher upfront cost, but it can lead to considerable savings in the long run. Enhanced durability reduces the need for frequent replacements, while the improved fuel efficiency achieved with lower rolling resistance tires contributes to decreased operational costs over the vehicle's lifespan.

Moving Towards Electrification

For those considering transitioning to electric fleets, incorporating the right tire strategy into your electrification plan is essential. Begin by evaluating your fleet's specific needs, considering the type of vehicles, their routes, and load requirements. Prioritizing tire selection can help ensure a smoother shift to electrification, reducing potential roadblocks and optimizing ROI from the start.
