Wheel Size and MPG

ziabmw · 11-18-2021, 08:42 AM

Just picked up an E70 with style 214 wheels (20s with runflats) and the gas mileage is really poor. I'm debating about switching to 19s with non runflats or just going with nonrunflats for the 20s. For anyone with 19s, what is your mpg like?

Our X5 is stock. I have 19s and I've been using Fuelio since December of 2019 to track my fuel. My average is 20.48 over that period. My best tank was 26.3 and my lowest was 18.6. It is mostly used for errands and chores nearby, but its definitely preferred for long distance trips as on a highway it is easily able to exceed its HWY mpg.
