Fleet tyre diameters have increased by an inch since 2023

The diameters of tyres fitted to fleet internal combustion engine (ICE) and electric cars have increased by an inch since 2023, new data from epyx reveals.

Information taken from the company’s 1link Service Network service, maintenance and repair (SMR) platform shows the average tyre fitted to an ICE car in 2023 was 17 inches and priced at £109 but had reached 18 inches and £122 by the end of 2025

Similarly, electric cars grew from 18 inches and £190 to 19 inches and £214 over the same period.

Tim Meadows, CCO, said: “There’s several ongoing trends here – most cars are getting bigger, SUVs are becoming more popular and larger wheels are preferred for cosmetic reasons – that are together driving increased tyre sizes.

“However, there’s no real upside for businesses operating cars. Not only do bigger wheels have a direct impact on tyre prices but also on replacement – larger, wider tyres tend to be more susceptible to punctures and kerb damage. 

“This leaves fleets in a position where they are spending more and more on tyres over time and, as can be seen from our information, this is especially true for ICE and petrol models.”

According to epyx’s data, only tyre sizes for hybrid cars have remained stable at 18 inches since 2023 and seen a reduction in pricing – from £181 to £166. 

Tim added: “There is no obvious reason why hybrids should be less susceptible to tyre size growth but it is reasonable to suggest these models are quite often more practical choices than electric cars, which still tend to be larger and more expensive, and petrol cars, which are sometimes bought for their performance. 

“However, what is clear from the platform is that fleets operating hybrids are making savings on tyres compared to those with other fuel types.”
