Itp Sand Star and 312 wheels for Dunes.

Hey all.
I’m looking at a set of front and rear sand tires for my 2016 Touring 570 SP. Liking the Itp Sand Stars and SS 312 wheels but wondering if spending the money on them will be enough of a difference than stock tires. Also wondering if the 12 inch wheels (4/156 ITP SS312 Alloy Series Wheel 12×7 4.0 + 3.0) will fit from the stock 14’s that the touring comes with will be ok. I checked Rocky Mountain ATV for sizing and pricing. Shows to fit but wanted to see if anyone here on forum has had experience with this setup on the Touring SP model?
Any good info would be appreciated.
