" ok take you stock trires and face them foward and see where you go .. around in a circle ... benn there tried that . the princel that makes a tire swim is bringing the water to the center of the tire . not throwing it out "
Ok, if you were refering to " stock " amphib tires such as rawhides or terra tires , I will agree with you on this . You are correct .
But , where ATV tires concerned , this is not true " most " of the time . My Gator tires won,t swim at all , backwards or forwards , but the Mud Bug tire will swim , and it is almost an indentical copy . The only difference is , the tire lugs are further apart and taller on the Mud Bugs , when compared to the Gators , and the outer curve of the tire lugs on the Mud Bug , is both longer and more pronounced . This is what makes them swim and the Gator tires don,t . This holds true with the High Lifter Outlwaws , because the outer tire lugs are curved to scoop mud and water , but the spacing of the center lugs shead mud , and do nothing for water propulsion . The Swamp Fox plus tire scoops water from the center and outer curvature of the lugs , and the Vampire tires scoop water from the center .
