Factory wheel question

I drive a 2014 Xp4 1000. I’ve ordered a set of 32×10-14 Roctane XDs to go on the factory wheels and replace my worn out bighorns. I’ve heard the factory rear wheels don’t fit the front of the machine (hence the spare tire is on a front wheel). Is this true?
Is there any reason to change out the rear wheels and go with factor front wheels all around (or factory rear wheels all around)? I know it would make tire rotations easy, but will the front and rear tire tracks be different by much? Would it look dorky? Don’t want to spend the bucks for new wheels, lots of used factory wheels available on craigslist. Thanks in advance for the input!
