The popularity of electric cars has continued to rise in recent years. This is not only because of trends, but also because of public awareness of more environmentally friendly vehicles. But when talking about electric cars, don't just focus on the battery or electric motor, there is one component that is often overlooked but is actually very crucial: tires.
Yes, electric car tires have different characteristics compared to conventional car tires. At first glance, they may seem similar, but the differences in material, design, and function are quite significant. Let's discuss them one by one.
Composition & Design: Efficiency is Key
In general, electric car tires and conventional tires are made from similar materials, but their development directions are different. Electric car tires rely on the Low Rolling Resistance (LRR) type. This means less friction with the road surface, allowing the vehicle to move more efficiently and conserve energy.
Meanwhile, conventional tires do not prioritize energy efficiency. Their designs are more diverse, depending on performance requirements, driving style, and vehicle type, ranging from sedans, SUVs, to trucks.
In terms of materials, electric vehicle tires are typically lighter and made with advanced technology to reduce friction and extend their lifespan. Conventional tires still rely on rubber and fiber compounds that tend to be heavier and less efficient.
Size, Profile, and Adaptation to Batteries
The design of electric cars, which have large batteries under the body, means that the size and profile of the tires are also adjusted. They are usually slimmer and taller to accommodate the heavy load and maintain comfort.
Conventional car tires also vary, but their purpose is more about durability in various road conditions and driving styles.
Emissions: Which is Cleaner?
When it comes to emissions, electric car tires are clearly superior. Since the car's power source comes from electricity, exhaust emissions such as CO₂, NOx, and other harmful particles can be minimized.
Conversely, conventional car tires still contribute to emissions from the burning of fossil fuels.
Performance: Traction, Handling, and Durability
Electric car tires are generally equipped with technology that enhances traction, especially on slippery or wet roads. Their design is also optimized for more precise handling. Moreover, the position of the battery under the car lowers the center of gravity, which automatically increases stability.
In terms of durability, electric car tires are usually more durable. They are designed to support the extra weight of large batteries, while also being able to adapt to extreme weather conditions, such as a more efficient water drainage system to avoid aquaplaning. Some even feature automatic pressure adjustment technology, which adjusts air pressure according to temperature or road conditions.
Production & Maintenance: More Expensive Upfront, More Economical in the Long Run
In terms of production, electric car tires are indeed more expensive. The materials and technology are no joke, as they must be durable and efficient at the same time. But on the other hand, maintenance costs are actually lower.
These tires rarely need routine servicing of the suspension or brakes because the electric car system itself is smoother in its use of power.
Conclusion: Choose According to Your Needs
In essence, both electric vehicle tires and conventional tires have their own advantages. Electric tires excel in efficiency and environmental friendliness, while conventional tires remain a flexible choice for various road conditions and driving styles.
