I am look for some new tires for my 2019 sportsman 570 and looking for some advice. I am looking for increased mud performance while maintaining a nice trail ride. I was looking at 27-9-12 maxxis zillas for the front and 27-11-12 for the rear. I was also looking at the 28-9-14 front and 28-11-14 rear. Is there a benefit on getting 14in wheels over 12in? Any other suggestions for tires? I am 300 lbs and worried about rubbing on bigger tires.
