What makes a tyre suitable for the additional weight of an EV?

A tyre suitable for an EV must have the correct load index and a structure designed to remain stable under the vehicle’s weight. This is particularly important because the battery pack can make an EV heavier than a comparable combustion-engine vehicle.

The correct tyre specification should always follow the vehicle manufacturer’s approved size, load index and speed rating. Choosing a tyre based only on its dimensions may result in an unsuitable load capacity.

Why Do EV Tires Wear Differently?

Aspect Ratio

Referring to the widest point of the tire, from sidewall-to-sidewall. Usually measured in millimeters, the larger the number, the wider the tire.

Rim Size (inch)

The rim size, measured in inches, is the distance measured between the two bead seat areas in a tire, where the tire and the wheel come together.

Load Index

The load index refers to the maximum weight a tire can carry when inflated to the correct pressure. The load index number corresponds to a maximum weight on the Tire Load Index Chart.

Speed Rating

Based on a speed rating chart, the tire speed rating refers to the fastest speed that the tire can safely maintain over time. With higher speed ratings, you will experience better control and handling at higher speeds.
