JARGON BUSTERS

Quick Guide to Markings & Features

• EVc (EV-Compatible): Specifically engineered to handle the high torque and battery weight of electric vehicles while offering the lowest rolling resistance to maximize ran
• XL (Extra Load): Indicates a reinforced tyre with a higher load index, designed to safely carry the increased weight of EV batteries and hybrid systems.
• S1: A specific manufacturer code (often linked to an OE fitment) indicating a focus on reduced rolling resistance or specific noise dampening properties.
• EverGrip Technology: A high-performance rubber compound and specialized tread design that maintains high-tier wet braking safety even as the tyre wears down.
• Maxtouch Construction: Maximizes the tyre’s contact with the road and evenly distributes the forces of acceleration, braking, and cornering to deliver longer tread life.
• CoolRunning Sidewall: A specialized sidewall design that absorbs less energy during flexion, significantly reducing energy consumption.
• Energy-Reduced Compound: A highly elastic compound that reduces energy dissipation, resulting in less rolling resistance and better fuel/battery economy

Popular Fitments

• Audi Q8 e-tron & Mercedes-Benz EQE SUV: Optimises range and handles high electric torque while providing a quiet, premium ride for luxury European electric SUVs.
• Toyota BZ4X & Lexus RZ: Maximises the efficiency of Toyota’s advanced electric platforms for high-mileage commuters with reduced energy consumption.
• Hyundai Ioniq 5 & Kia EV6: Supports the advanced 800V architectures and increased battery weight of Hyundai’s award-winning electric CUV range.
• Nissan Ariya & VW ID.4/ID.5: Specifically engineered to enhance the aerodynamics and battery longevity of popular electric crossovers and SUVs.
• BMW iX & Polestar 3: Delivers precision efficiency and sustained performance for high-end European electric luxury SUVs and crossovers.

Load Rating: Maximum Weight Capacity Explained

The load index is a numerical code representing the maximum weight in kgs that a single tyre can safely carry. To ensure safety, the combined capacity of all four tyres must exceed the vehicle’s total weight when fully loaded.

Speed Rating: Maximum Velocity Explained

Represented by a letter, the speed rating indicates the maximum kph a tyre can maintain over a prolonged period. Higher speed ratings are engineered to handle the heat and stresses generated at faster speeds more effectively.

Quick Reference Guide

• Check your requirements: You can find the specific requirements for your vehicle on the tyre information plate (usually located on the driver-side door pillar) or in the owner's manual.
• Replacement rule: It is vital never to fit a tyre with a lower load index or speed rating than those recommended by the manufacturer.
• Common Ratings: Standard ratings include T (190 kph), H (210 kph), and V (240 kph). You can view a full conversion table below..
