Over the course of last year, some Italian, Spanish and English farmers were able to attend the field tests organized by Yokohama-Atg to directly and objectively demonstrate the operational potential of its Alliance series “Agri Star II” and “Agriflex+ 372” tyres. The tests were developed using Fendt “728 Vario” tractors and as a whole they tended to demonstrate how the very high flexion technology “Vf”, “Very High Flexion”, improves traction and minimizes compaction thanks to the footprint the wider footprint induced by the tires on the ground which induces lower specific loads. The loads are also distributed in a balanced manner between the center of the tire and the sides, a factor which reduces slipping, having a positive impact on reducing consumption and on the health of the soil. One of the highlights of the day was the live soil profile analysis, which compared the effects of “Vf” tires and standard radial tires on compaction.
Using an excavator, Alliance technicians excavated the soil perpendicular to the tracks left by the tractors, allowing them to observe first-hand the deformations suffered by the soil layers, from the superficial to the deepest. Further demonstrations also confirmed the relevance induced by inflation pressures on the overall efficiency of a work site.

Appropriate inflation reduces rolling resistance, prolongs the useful life of the tires and guarantees safety, particularly when operating on the road with heavy trailers in tow. The protagonists of the events were the “Agri Star II” and “Agriflex+ 372” tyres, with the former characterized by the “Slt” technology, “Stratified Layer Technology”, which allows the traction capabilities of the tire to be kept unchanged for most of its useful life.
“Agriflex+ 372” instead boasts a carcass reinforced with steel belts to give rise to superior load capacities and crampons shaped to ensure maximum self-cleaning capacity and therefore always optimal traction in the field. It should be underlined that both tires boast particularly wear-resistant compounds and therefore represent an investment destined to last over time even in the case of intensive use of tractors such as those advanced by contractors.
