Can air really improve battery life?  

We project about 160 million electric vehicles on the road in 2040. First of its kind testing has shown that a simple factor could be robbing them of performance: air! Electric vehicles suffer four times more effect from rolling resistance than ICE vehicles, and that means that a small decrease in tire inflation could lower battery range by 3-7% and cause tire life to be 16% shorter. In electric vehicles, air retention matters.

Does tire inflation affect the battery range of electric cars?

The impact of air loss

Tire air retention is important in all vehicles, but is especially so in electric vehicles. EVs experience more than four times greater effect from rolling resistance – this can compromise tire life and reduce EV battery range.

EV tire air loss impact study

In a first-of-its-kind study, ExxonMobil engineers conducted real-world road tests to measure the impact of air loss in electric vehicles (EVs) – specifically, the impact on energy consumption and vehicle range.

Watch the video to find out how the tests were conducted and to see the revealing data the tests produced.
