Very aggressive tires, look great. Installed on 2006 Polaris Sportsman 500. 1 1/4" lugs produced a little power loss, but Sportsman is stout enough to handle it. Just have to get into throttle a little more. With Sportsman's already ample ground clearance, these tires set it up even more so it towers above the other ATVs my buddies have. It turned my 'hoss' into a 'beast'!
