Yokohama OHT has introduced the new Alliance 399, a tyre engineered for excavators. Featuring a non-directional diagonal lug design, the 399 is made to offer boosted traction in both forward and reverse directions. The Alliance tyre therefore increases operational flexibility and efficiency on and off-road. Also designed with a sturdy construction for higher reliability, the Alliance 399 is suited to contractors using compact excavators in various applications, including construction, agriculture, local authorities, forestry, mining, and industrial sectors.

The Alliance 399 boasts a steel-belted construction and a specialized tread compound, ensuring stability and resistance to cuts, chips, and chunks. These features result in minimal downtimes and an extended service life, even in the harshest conditions. Complemented by high non-skid depth, angular blocks, and centre blocks with tie bars, the tyre delivers durability and stability. Its open shoulders facilitate effective self-cleaning—a crucial advantage for excavators navigating various work sites.

The Alliance 399 also features a wide footprint, prioritising soil protection during off-road excavator operation. Compared to frequently mounted duals, its wide tread prevents stone trapping, a common issue.

Yokohama summarises the five key benefits of the Alliance 399: the tyre offers stability, minimising risk of tipping over on uneven terrain; comfort for operators while driving long-distance between work sites; multi-functionality, which is useful for excavators, which use different attachments, so need tyres that can carry heavy loads and stay stable for all kinds of jobs; low ground pressure when working on soft or muddy soils, with a design that reduces pressure, preventing the excavator from getting stuck and minimising soil disturbance; and a tyre that prioritises fast and safe working conditions.

This tubeless tyre is available in three sizes: 650/45-22.5, 600/50-22.5, and 600/40-22.5. Two additional sizes, 710/40-22.5 and 500/45-20, are currently in development, Yokohama OHT adds.
