The Alliance 318 Super Grip E-3 (G-3/L-3) is a massive heavy-duty tire that provides better gripping in construction, mining, logging and rock service jobs. It has an all-round centre tread belt which makes it a tough tire. The extra wide lugs of the tire provide superior traction and long mileage. The 318 is a non-directional tire with a special compound that resists cuts, shipping and wear. This is a tubeless tire made of nylon construction.
