The Polaris 850 XP Sportsman is my first quad I have ever owned! I have ridden quads over the years and just assumed that the tires that came with the quad were the best! Well, my assumption was wrong. Like automobiles, quads come with a standard tire issue. When you start riding you notice things and accept it! I replaced the rear tires first with Artrax CTX and realized the aggressive treads kicked butt on all surfaces! Supremely on snow when plowing! I didn't change the front tires right away.... After losing traction during plowing, I replaced the fronts.... What a difference!
Artrax is Motosports in house tire! For the price, performance, and customer service.... It's the only tire to go with... I recommend them highly. If you are worried about a rough ride on paved surfaces, don't be! They are super smooth!
