Electric vehicle tires are more prone to failure, reveals study

Despite the growing popularity of electric vehicles, a new study has highlighted an issue regarding their tires and wheels that could lead to additional maintenance and repair costs for owners.

Research conducted by the British Vehicle Rental and Leasing Association analyzed data from over 47 million MOT tests in the UK. The findings revealed that electric vehicles are approximately 1.8 times more likely to experience wheel-related faults compared to petrol-powered vehicles.

Heavy Batteries: A Major Factor

The study identifies the heavy batteries installed in electric vehicles as a primary cause of this issue. The battery packs in some electric vehicles can weigh between 299 and 499 kilograms, accounting for roughly 25 percent of the vehicle's total weight.

This extra weight places increased stress on the wheels and tires, raising the likelihood of wear and tear or damage.

Instant Torque: Added Strain on Tires

Another significant factor contributing to tire stress in electric vehicles is the instant torque delivered by the electric motor. Unlike traditional petrol engines, electric motors provide high torque almost immediately upon acceleration.

This added force exerts greater pressure on the tires, increasing the risk of wear and damage over time.

According to the study, owners of certain electric vehicles are facing additional expenses for tire replacements and other related repairs. Replacing premium tires, in particular, can sometimes cost up to hundreds of pounds.
