Alliance tyres for extreme loads

May - June 2024 | Back

Alliance 373 VibroFarm is the new offering from Japanese manufacturer Yokohama Off Highway Tires (YOHT). It is a tyre designed specifically for the Iberian market, to meet the needs of those who use tractors for work requiring equipment to be mounted at the front of the vehicle, such as vibrating systems and loaders for harvesting olives, pistachios and grapes.

The application of these devices results in a significant load on the front axle of the tractor with an uneven weight distribution, which causes greater stress on the tyres. The solution offered by Alliance 373 - fine-tuned through user surveys and field tests - features a steel-belted reinforced carcass that ensures strong tyre and machine stability during operations, even under extreme loads.

Also used for this tyre is Stratified Layer Technology (SLT), a technique developed by Alliance that guarantees high traction and reduced skidding, particularly for activities in extreme environments, such as slopes with very wet terrain. A technique that also enables self-cleaning of the tyre.

Other features of the Alliance 373 are: sinusoidal centre rib for high performance due to minimised rutting; multi-angular sidewalls provide good traction on soft surfaces; increased number of blocks and high rubber-to-void tread ratio enable low rolling resistance on hard surfaces; graded lugs with mud breakers for increased self-cleaning capacity and high traction; diverging groove design which, in combination with an optimised draft angle, minimises stone entrapment.

These elements together favour a longer tyre life, which is covered by a 10-year warranty. For Sandeep Unni, Vice President of South YOHT, "the new Alliance 373 is a good example of the solutions we can offer: technically innovative and designed for specific markets.”
