Alliance has unveiled to new two new patterns in it renowned Forestar III series: Forestar 643 III and Forestar 644 III.
Both tyres were especially developed for forwarders and harvesters to ensure maximum traction and performance under all circumstances. With and without boogie tracks, these new tyres reliably deliver in all kinds of heavy duty forestry operations. The unique tread patterns ensure that both tyres are compatible with boogie tracks even with heavy loads and when operating under wet soil conditions.
In addition to providing maximum traction, effectively protecting the soil against compaction is a key objective of Alliance. That is why an extra wide tread width and a wide tread radius were chosen, thus ensuring that Forestar 643 III and Forestar 644 III deliver maximum traction with minimum compaction. At the same time, the wide foot print of the Forestar III series offers enhanced driver comfort.
Forestar 643 III
As one of the most advanced solutions in forestry tyres, the brand new Alliance Forestar 643 III is engineered for ultimate track compatibility. When used without boogie tracks, however, this tyre equally provides exceptional grip also under critical forestry conditions. This tyre is characterised by outstanding stability, excellent self-cleaning abilities and its resilient construction.
The improved heavier nylon construction and special steel belts ensure high load carrying capacity and excellent puncture resistance whilst the reinforced hexagonal bead technology prevents rim slippage and bead failure.
The flat tyre profile and horizontal groves were specifically designed for unparalleled track grip. At the same time, wider lugs at the shoulder provide extra support to track paws and enhance overall stability.
As also minimising downtime is one of the important objectives in the development of Alliance yres, particular attention was given to the curb-rib design, to the unique shoulder buttress design, and to inter lugs around the shoulder of the Forestar 643 III. These features contribute to increased protection against side impacts and cracks as well as increasing puncture and penetration resistance.
The Alliance Forestar 643 III is available in sizes 710/40-22.5, 710/45-26.5, 750/55-26.5 and 780/50-28.5.
Forestar 644 III
Designed with a dual lug angle, the Alliance Forestar 644 III simply provides incredible grip and traction. The sturdy construction of this tyre ensures exceptional performance – thus also beating the most challenging working conditions. Thanks to the tyres’s remarkable resistance against damage, tyre life is maximised.
Just as Forestar 643 III tyres, also the Forestar 644 III features an improved heavier nylon construction with special steel belts and the reinforced hexagonal bead technology. These characteristics ensure excellent puncture resistance and high load carrying capacity whilst preventing rim slippage and bead failure. The low lug angle at the shoulder enhances traction whilst the higher lug angle at the centre contributes to the tire’s high durability. The wide lug centre block ensures stability and ride comfort, and the large tread width allows for a wide footprint
which results in reduced ground pressure.
The Alliance Forestar 644 III is available in sizes 600/50-22.5, 710/40-22.5, 710/40-24.5, 600/55-26.5, 710/45-26.5, 750/55-26.5, 800/40-26.5, 710/55-28.5 and 780/50-28.5.
