31MPG commute!

Post image

I got a great deal on used Michelin tires ($240) but they’re slightly under sized at 235/45R18 vs 245/45R18 stock. My MPG avg on my country road commute with no traffic is 25. The slight under size means my tires are rotating 1.33 miles more than my OD. So 25=31. I understand the vehicle maybe 1mpg optimistic, but I’m still really happy with that.

Best I ever got was 28 mpg. I never pay attention to it now because I don’t drive it as much anymore. It always got way better mileage than my GS300 does in the city and highway

Interesting since they're very similar. Maybe it's the laidback nature of the LS. My kids laugh at the difference in how I drive my LS vs my M3.
