Trying to decide between tire sizes on a 2016 Sportsman 850 SP. Thinking 28x9 on front, and 28x11 on back. Do they measure big or small. I'm wondering if anyone has direct experience with this setup. If the tire does measure small, I'm sorta thinking 30's, same width front and back. Anyone fit the 30's on a stock setup or maybe with a 2 inch lift? Don't think 30's would be that hard on it, it's a fairly light tire. It has 28 inch Blackwaters on it now, that are going to my girl's new 570. Thanks.
