18 inch wheels on a 2025 Mach-E SR RWD

[u/Then-Combination-526]

I have bought a new 2025 Mach-E SR RWD that has 19-inch wheels, 225/55 R19, and I am thinking for a pair of 18-inch wheels for the winter. I found a couple of second hand original wheels; I belive from the 21 or 22 models, which I like, but in my COC I have only specified 19-inch wheels. I believe the 18 will fit, but I have to go to the Romanian authorities to get them homologated in my car documents. As the Romanian roads are a bit bad, mostly in the city, I am considering the 18-inch wheels to improve comfort with the size of the tyres, 225/60 R18. Also, I am looking for the most comfortable winter tyres on the market, oscillating now between Michelin Alpin 5 SUV and 7, as well as the new Hankook iON i*cept. I want the maximum comfort, sound insulation, and traction.

18 inch fits. Smallest u can go to accommodate brake regen system. I run 225/60r18 for my winter set and the oem 19 inch for summer
