To make a swap or what?

Thinking about doing a wheel size swap on my 2019 and wanted to see what others have tried. I'm currently running the stock 18s, but considering going up to 20s but I'm having second thoughts on how much ride quality I'll be giving up or if there'll be any rubbing or clearance issues.
Has anyone here gone from 18s to 20s or even dropped down to 17s, would love to hear what tire sizes you paired them with and whether you had to do any further mods like the speedo or suspension
 
@Samuella.Jones Switching wheels on your 2019? Yeah, that's a classic!
when you switch 18s to 20s, expect a stiffer ride (less tire cushion), and you absolutely MUST check tire size to avoid rubbing. Keep the overall diameter super close to stock, and your speedo should be fine. Suspension mods aren't usually a must do unless you want to lower it. 18s to 17s, on the other hand, usually give you a comfier ride
