304

The Alliance 304 is an R-1 tread drive wheel tire for application as a rear tractor tire. Its knife-like lugs are designed for deeper penetration of the ground. The double-angle design with a wide space between lugs ensures efficient self-cleaning properties in any kind of soil. The design, based on 45 angle bar with center studs, provides better resistance to side slippage and continuous rolling. The tire is recommended for hillside operations and for occasional short drives on the road. A strong nylon carcass guards against mechanical failures and moisture deterioration.
