The Loadstar K399 Trailer Tire features a computer-designed tread that delivers a radial tire appearance, but with a bias tire's durability. The advanced rubber compound gives longer tread wear and low rolling resistance. The flatter tread profile provides increased towing stability. Wide profile trailer tires are ideal for large weight distribution. Better traction and handling also mean more stability in turns. The 10" x 6" solid wheel is corrosion-resistant for reliable, long-lasting life.
