Hi guys, i'm shopping for bigger wheels for my 2017 XE 25t and found a great used set that came off an XF. They're 19" and I know they're a bit wider. Has anyone ever used this setup?

 

They will definitely bolt on. We would need more info on the wheels in consideration to tell you if they'd actually fit in the wheel well and around the brakes...

 

Generally, yes. Although some Jaguars have staggered wheel setups that may be less swappable.
Bolt patterns are consistent, so wheel diameter, width, and offset are the primary concerns. You can check these thru the dealer or a site like Tirerack.com
