Electric cars are generally much heavier than traditional vehicles, have higher torque and need reduced rolling resistance to maximise driving range. This can mean that traditional tyres can get worn down more quickly or perform less well. So tyre makers have been working on new products specifically for EVs. Both Goodyear and Hankook have recently launched new ranges.
Goodyear has enhanced its existing tyre range, the Goodyear Eagle F1 Asymmetric 6, the UltraGrip Performance 3, and the Vector 4Seasons Gen-3. These tyres are now designed to cater not only to traditional internal combustion engine (ICE) vehicles but also to the requirements of EVs.
Though the enhanced tyres are engineered to support both EVs and ICE vehicles, the particular focus of these improvements revolves around handling the unique attributes of electric vehicles. This includes adaptations to tread patterns, rubber compounds, and structural designs to deliver low rolling resistance, high durability, and improved load-bearing capacity.
Hankook Tire has also launched an innovative line of tyres specifically designed for EVs, the iON evo series, an EV-centric tyre line that promises enhanced durability, grip, and longevity.
Hankook has integrated several advanced technologies into the iON evo tires to address the distinctive needs of EVs:
i Super Mileage Technology: This innovation incorporates a blend of eco-friendly materials with a high concentration of silica. This combination is crucial for extending tyre lifespan and improving overall tyre health, directly addressing additional wear issues.
EV Contour Technology: Designed to bolster lateral rigidity, this technology enhances the tyre’s ability to support the extra weight of EVs. According to Hankook, lateral rigidity is improved by up to 25%, and cornering rigidity by up to 20%, compared to conventional all-season touring tires for ICE vehicles. This development aims to maximise grip, ensuring safety and performance.
Reinforced Construction: The iON evo tyres incorporate high-strength steel and reinforced steel belts. High-strength steel boosts durability and comfort, while reinforced belts enhance endurance during high-torque moments typical of EV acceleration. The tires also feature a mono-layer structure of fibre stiffener, which reduces rolling resistance and improves sidewall stability. Further augmentations include folded-edge tape between belts for added durability and a jointless bead wire for increased binding force, ensuring the tire remains securely attached to the wheel under the strains exerted by EVs.
It’s often said that the tyres are the most important part of the car – if you’re investing in a cutting-edge EV, it’s well worth making sure that you also fit the most appropriate, best-performing tyres. If you’re unsure, ask a tyre specialist!
