Looking at upgrading my wheels. I was wondering what people have put on with no problems. I wanted to go with a slightly bigger setup to fill the arch of the wheelwell. But after looking at the setup the stock wheel is pretty close to what looks to be the upper control arm. My 19x8" wheels are around 27.68"(245/45/19). I wanted to do 21x9" (255/40/21) wheels with an overall 29" height. Offsets would be roughy the same. Anyone feel free to chime in.

2017 Qx50 forgot to note that

If it's the same sizing as the EX35, which I would assume it is, you'll likely need a lower profile for 21", a 35 possibly? A 40 sidewall is proper for a 20" wheel. There's a tire calculator on 1010tires.com you can use to check sizes. I used it a fair bit when I got my new wheelset.

Yah probably gonna go with a 20" wheel with a 40 or 45 profile. Wanted to gain a little larger circumference without running balony skin tires on a 21".
