Electric company car tyres are on average both bigger and more expensive than petrol or diesel equivalents, new real-world data indicates.

The epyx data indicates replacement tyres for EVs are on average 59% higher than for ICE cars

Data from epyx reveals the average replacement tyre fitted to an electric vehicle is 18.59 inches and costs £207 while, for internal combustion engine (ICE) cars, the corresponding figures are 17.40 inches and £130 – equating to a 59% uplift in tyre costs for EVs.

The data comes from the company’s 1link Service Network, which is used to manage service, maintenance and repair (SMR) for more than four million company vehicles.

The tech solution firm, which is exhibiting at this April’s Great British Fleet Event, said the uplift in costs was partly the result of EV carmakers’ current focus on larger cars, which meant there were comparatively few smaller vehicles available.

But Charlie Brooks, growth director, added: “Even bearing that in mind, the data does suggest that EV tyres are currently more expensive than ICE tyres in operational terms both because of their bigger size and the fact that many specialist electric car tyres simply have higher price tags. The price differential indicated is relatively wide.”

He added that epyx had limited data so far on EV tyre wear and replacement but hoped to create meaningful comparisons with ICE vehicles soon.

“Compared to petrol and diesel cars, there are relatively few EVs that have been on fleets for a complete 3-4 year cycle, so we don’t have a comprehensive picture of tyre replacement. This is quite a complex area, with specialist EV tyres often having characteristics such as different compounds, reduced tread depth and reinforced sidewalls, all of which could ultimately have an impact on wear rates and damage.

“As the picture becomes clearer over time, we plan to release more information. Building a complete picture of how EV and ICE running costs compare is very much an ongoing process for us at this moment in time.”
