The DF-1 tyre has a special improved tread pattern. The geometry of
lugs and lug base spherical radius have been changed. Those changes
improved tyre safety during corn harvesting. The aggressive crop residues
are not blocked by the lug any more, but gently bent outwards, preventing
early failure.
High-strength anid cord which is used in the production of DF-1 tyres
has improved the temperature stability as compared to standard cord
(any tyre heats up during long-term continued operation and the cord
strength declines). In addition to the improved heat resistance this cord
has improved strength properties, which allow to increase the load index
up to 172 and reduce the number of carcass plies. This ensures lower tyre
weight, floor pressure and fuel consumption
