Hi, i'm from Brazil and i bought a Fusion Hybrid 2017, but it came with 215/55 R18 tires, here in Brazil stock tires are 235/35 R18.
215/55 R18 revs 17 times less than stock tires, according this website (tire-calc.com) each rim.
I use most of times in city, not highway, and my mileage ins 27MPG, we have many climbs here.
Maybe this tires make a high fuel consumption?
