A365 AGRI-STAR R-1W, high performance tire for high HP tractors

As demand on agricultural production is increasing, farmers practicing modern agriculture have resorted to advanced and more powerful machinery to tackle the need for increased productivity.

Technical improved tractors require technically advanced tires to carry more load, be able to keep higher speed, minimize soil damage and have minimum downtime. Statement also confirmed by Gregorio Stefanucci, ATG’s client and owner of Azienda Agricola Stefanucci & C., few kilometers from Pisa (Italy) and its famous leaning tower. “Agricultural machines are becoming bigger and bigger. At the end of the road, there is only one thing we are looking for: tires able to stand the strain of heavy soils and heavy tractors”. His John Deere 8400 has been equipped with a set of A365 AGRI-STAR (600/65R28 and 710/70R38) since July 2015. “In these areas ground is really difficult, characterized by loamy soil” explains Stefanucci. After having run for more than one year, A365 behaves at its best. “Former tires from a premium brand gave me lots of problems with sidewall hernias, thanks God I completely forgot about that issue since we mounted AGRI-STAR” the contractor confesses with relief.

The Alliance 365 tread pattern represents the family of modern radial agricultural tires with low aspect ratio: the optimum number of elastic and asymmetric lugs promise excellent self-cleaning capability, large footprint provides stability and reduce soil compaction. “The strong carcass constructed with rigid belts ensure the long life of the tires in demanding agricultural jobs and cycle” points up Emiliano Bertolini, ATG Field Engineer “A365 is even steel belted in size 710/70R42, the only tire on the market with this feature”.

This large volume low aspect ratio tire is designed for high HP tractors and is available in a full range of sizes for front and rear axle combination.

Same positive feedback from Federico Tirabasso, ATG testimonial and owner of the homonym company, located in the province of Livorno (Italy). “After almost 500 hours work these tire have consumed less than 3 mm”, states ATG Engineer Emiliano Bertolini while measuring the tread of his A365 AGRI-STAR (540/65R24 and 600/65R38). The set has been mounted on a John Deere 6810, used mainly for seeding and ploughing. Bertolini adds: “These tires last long enough to provide good returns on investment. During independent endurance testing has been proved that Alliance 365 has a much lower rate of wear when compared to other brands: the average value is 125 hours per millimeter”.

ATG Engineer brings attention on the lugs: “Their 45 degree design with overlapping in the center guarantees great grip, a smooth ride and stability on hard surfaces. Traction is the most important factor for High HP agricultural tractors. The tire’s tread design plays a key role in providing high levels of traction. A365 design is able to penetrate soil well and provide maximum possible surface contact and consequently higher traction”.

Last but not least, focus on driver’s comfort index: it is important to remember that tractors normally do not have a suspension system, it is the tire itself that doubles up as suspension. A365 AGRI-STAR helps in producing less noise than other competitors: the ride is not only smooth, but also pretty silent.

Alliance new generation radial tires range features also A372 AGRIFLEX and AGRIFLEX+.

“A372 AGRIFLEX is the object of desire for professionals looking for premium technology, the one tire that you want to see on your high power machines” comments Bertolini about Alliance top quality tire for tractors and combine harvesters.

ATG is a leading brand in Improved Flexion and Very High Flexion technology and A372 speaks itself: it has a stubble guard compound and it’s one of the few on the market which presents a steel-belted carcass for superior puncture resistance and uniform ground pressure.

Comparing to regular radial tires, AGRIFLEX IF has 20% more load carrying capacity, that increase to 40% more if machine fits AGRIFLEX + VF. They can therefore do more work by causing minimal soil compaction, enable better fuel efficiency and attain higher road speeds, which are the most important requirements for modern agricultural practices.

“No matter the tractor’s power, no matter the job to be done” concludes Bertolini “There is a perfect Alliance radial for all applications”.
