My 2011 F150 Ecoboost has been returning excellent MPG lately, in fact the MPG has been steadily but slowly improving over the last 6 months. I was actually over 21MPG average for the first time ever. I started thinking about how the engine is finally broken in at 140,000 miles, or maybe it's running a bit lean,,, who knows. But I was not complaining.
Well fast forward to this week with a new set of (same as before) Michelin/Costco LT tires. MPG is back down to 16.5-17 and the truck feels like it's being held back a bit. The new tires are great in the rain, and ride really well. But they absolutely have reduced MPG. Yes, the old tires were down to the tread wear indicators.
