2013 850XP wheels on 2011 800 Twin EFI?

Hello all. This is my first post. I’m just getting back into ATVing after being out for about 10 years. My last ATV was a new 2005 Sportsman 500HO.
I just bought a 2011 Sportsman 800 Twin EFI. By my measurements my wheels have 5/2 front and 5/3 rear offset. I have found a set of 2013 850XP ALUMINUM 14 inch wheels w new 489s on Craigslist I’m interested in.
Does anyone know what the offset on the XP wheels are? I asked the seller to measure offset and he didn’t understand what I was asking and he is a couple hours away. I do not want to widen the track of my 800 due to I’m building an ATV carrier for my truck to haul two 48inch ATVs.
Thanks in advance.
