Electric Vehicles (EVs) have a higher rate of MOT tyre failure compared to petrol cars, according to a new analysis. The Institute of the Motor Industry (IMI) has revealed that EVs have a 40% higher MOT tyre failure rate due to their greater average weight. The report analyzed data from 2021 and found that the overall MOT failure rate for newer EVs, caused by various factors, is slightly higher than that of petrol vehicles.
The weight of EVs is responsible for the higher tyre failure rate, as they are on average 25% heavier than their petrol counterparts. The IMI report highlighted that heavier EVs put more strain on suspension components and wear down tyres more quickly. It also suggested that the greater torque delivery in EVs, particularly from a standing start, could accelerate tyre wear compared to traditional combustion engines.
The report compared Department for Transport data from 2015 to 2018 and found that 46% of EV MOT failures were due to tyres, while the rate for petrol cars was 32%. Looking at all cars registered between 2015 and 2018, the relative difference is 40%.
In addition to the higher tyre failure rate, the report also revealed a shortage of skilled technicians qualified to fix EVs across the country. It identified 150 local authority areas where less than 2% of trained mechanics could repair electric vehicles. This shortage of trained technicians could have implications for the attractiveness of EVs, as consumers may be deterred by the prospect of not being able to get their vehicles fixed.
Despite the findings, EVs are still considered easier to maintain compared to traditional petrol and diesel vehicles due to their simpler operational makeup and fewer mechanical parts. However, the IMI data showed that newer electric vehicles were more likely to fail an MOT compared to petrol equivalents, specifically due to tyre wear.
As the number of EVs on the road is expected to increase significantly, with the UK government planning to ban the sale of petrol vehicles by 2030, it is crucial to address the shortage of qualified technicians. The IMI estimates that if training of new technicians and vehicle ownership continues at the current rate, there could be a shortfall of 16,000 workers by 2032.
The IMI report emphasizes the need for drivers to check their tyres regularly, along with lights, and ensuring regular servicing to keep their vehicles in optimum condition. By prioritizing maintenance, all drivers can ensure their wheels stay on the road, regardless of whether they drive an electric or petrol vehicle.
Ultimately, the findings highlight both the benefits and challenges of EV ownership. While EVs offer a greener and cleaner form of transportation, their heavier weight contributes to a higher MOT tyre failure rate. Additionally, the shortage of qualified technicians poses potential difficulties in getting EVs repaired. It is crucial for the industry to address these issues to maintain the growth and attractiveness of EVs in the coming years.
