AGRI STAR II, the tire that sheds its skin

The new Stratified Layer Technology (SLT), used for AGRI STAR II tires by the Alliance Tire Group, was presented at Fieragricola in Verona. The innovation developed by Alliance technical department, allows their tires to be widely applied to various agricultural work environments, even the most demanding. Each crampon is made up of two layers with a different profile. The upper layer has a single-angle profile, while the lower is made with a multiple-angle profile compensating for the loss of tire performance because of the wear. Together with the more aggressive tread and the optimal number of crampons, the succession of these two layers ensures that crampons perform much better, which means stronger traction on the field.

SLT technology allows to increase the life of the tire. In fact when the upper layer of the crampons - about 40% of the tread depth - wears out, the lower layer comes into action and the crampons change geometry. This new layer offers in turn as effective traction as that offered by a new tire.

The high volume of the rubber in the center of the tread and the greater stiffness of the structure, combined with the special design of the crampons, allow AGRI STAR II - says a note from the manufacturer - to offer high comfort, stability, and excellent road grip, as well as improved anti-slip and braking characteristics. The D speed rating, i.e. 65 km/h, of this tire, is a further distinctive factor in addition to its high performance. This tire is also characterized by broad shoulders that protect the soil and the crop when working in the field and on the grass. The AGRI STAR II tires are also equipped with the special Stubble-Guard compound, which ensures the effective protection from stubble damage, while the polyester housing is effective in maintaining the shape of the tire unaltered over time even in the event of overheating.
