THE Alliance 643 Forestar III tyres can now be fitted with another major track brand. 

Parent company Yokohama-ATG (Y-ATG) has announced that the product has been approved by Olofsfors, joining Clark Tracks and Pewag in giving the greenlight to the tyres. 

According to the firm, customers can now change their tracks with the same track number on 710/45-26.5 Alliance 643 Forestar III.

A press release from Y-ATG read: "Forestry tyres must be durable, stable, and able to handle steep slopes safely and efficiently. 

Forestry Journal:

"Tracks on tyres improve grip and traction, especially on challenging terrains. Simplifying track mounting or change enhances grip, stability, and safety, elevating operations on steep or soft ground. 

"The Alliance 643 Forestar III not only offers exceptional durability, but also boosts efficiency by seamlessly integrating with Olofsfors tracks." 

According to Y-ATG, the Alliance 643 Forestar III is "equally capable" of operations with and without tracks. The larger tread radius and flatter tread profile, horizontal grooves for enhanced track fitment as well as flat centre lugs for improved traction make for "perfect track compatibility". 

The tyre comes with reinforced nylon casing and advanced compounds that provide 120 per cent of the wear resistance and chip/chunk resistance of standard forestry compounds. It features steel belts, hexagonal bead technology (prevents rim slip and bead failure), wider shoulders and a unique shoulder buttress design (strengthens the sidewall).

Forestry Journal:

The 643 Forestar III tyre range "offers efficiency, safe operations and effective soil protection" with sizes 710/40-22.5 (TT & TL), 710/40-24.5 (TT), 710/45-26.5 (TT & TL), 750-55-26.5 (TT & TL) and 780/50-28.5 (TT & TL). 

The release added: "710/45-26.5 (seamlessly compatible with Olofsfors tracks and effortlessly interchangeable for enhanced functionality) is available in 20 PR for tube types and 24 PR for tubeless types."
