Just sold KQ and now same issue with Polaris 2016 570SP needing aggressive lite tire, similar to Big Horns but liter. SunF has a copycat, look alike tire for half the price as Big Horn $350, with good reviews, but also too heavy, for mainly fast trail use, very little mud, mainly sand trails. Like the quick response, of stock tires with good tread still, yet tends to wander a lot at higher speeds in sand. Any suggestions would be appreciated, at wits end here lol. 570 is a fast machine but wouldn't take much to slow er down with unnecessary extra weight, in tires, cargo, etc.
