The Alliance 354 has state-of-the-art materials and the steel-belted construction allow VF (Very High Flexion) and IF (Increased Flexion) radial tractor tires to deliver outstanding performance in any conditions. VF tires carry 40% more load on the same inflation pressure as conventional radials, or require 40% less inflation pressure for the same load, to reduce soil compaction. IF tires carry 20% more load on the same inflation pressure as conventional radials, or require 20% less inflation pressure for the same load. (TUBELESS - STEEL BELTED - STUBBLE GUARD)
