Are 20"s too much for a 19' Ecoboost?

[GearHeadGuy]

I everyone, recently picked up a new to me 2019 Ecoboost and I am looking to swap ugly multispoke black wheels previous owner installed on the car with some nice chrome deep dish rims (I think they'll look much better on a black Mustang but IDK). So sizewise, are 20"s too big for it? It's on 19"s now, and I think there is a good space for the 20"s, but who kows, it may be a bit of extreme.

20"s are fine, from what I tried 20x9 square cause no problem with fitment and look good (unless you want to track it).

Edit. But yea backspacing and ET matter, so better make sure the exact rim you chose is within the safe range for the Ecoboost

Thanks. that's exactly the size I'm looking at. So I think about Niche Misano wheels in 20x9 with 35mm offset on carid site

but it doesn't say anything about the backspacing. Do you think I need to call them in to find it out?

I don't know if you already called them, but no, you don't need to check the backspasing. The offset tells it all and 35mm should be fine for this size. Google some wheel size calculator to compare your current wheel size with the new rims - it'll show you if its within the limits
