Electric vehicles are 1.8 times more likely to have tire failure

Despite the advanced technology in electric vehicles, they have shown a higher likelihood of wheel and tire-related issues compared to petrol vehicles. A recent study indicates that electric vehicles are approximately 1.8 times more likely to experience wheel-related faults than their petrol-powered counterparts.

Research conducted by the British Vehicle Rental and Leasing Association analyzed data from over 47 million MOT tests in the UK. The findings revealed a higher rate of tire-related defects in electric vehicles.

Heavy Batteries and Instant Torque: Key Factors

According to the study, the heavy batteries used in electric vehicles place extra weight on the wheels. The battery packs in some electric vehicles can weigh between 299 and 499 kilograms, accounting for up to 25 percent of the vehicle's total weight.

Additionally, a key characteristic of electric motors is instant torque. Unlike petrol engines, electric motors deliver high torque almost immediately upon acceleration. This extra force increases the stress on tires, making them more prone to rapid wear or damage.

Issue More Pronounced in Older Vehicles

The study also found that tire-related problems were more evident in relatively older electric vehicle models. Faults related to friction-based braking systems were also reported in some vehicles.

According to the association, these issues are forcing some electric vehicle owners to incur additional costs for repairs and tire replacements. Replacing expensive or premium tires, in particular, can cost hundreds of pounds. The report attributes the overall high rate of tire failure primarily to the heavy batteries of electric vehicles and the high torque available instantly at low speeds.
