Yokohama Off-Highway Tires’ (YOHT) flagship brand Alliance has recently released new sizes of the proven Agriflex+ 372 radial tyre for tractors and harvesters.

This includes a size that makes it the largest tyre ever produced by the brand. Size VF750/75R46 is for the absolute largest tractors and machines, while offering economically and qualitatively competitive tyres. Alliance VF tyres are already globally well-established as leaders in the flotation radial market. Key benefits of their technology include effective soil protection, efficiency gain and yield increases.

Yokohama Off-Highway Tires’ Alliance 372 and 389 VF tires allow for higher profitability according to a recent study in Denmark.

Alliance Agriflex+ 372’s success was highlighted in 2021 by a scientific field experiment conducted by Danish research body SEGES Innovation. Results of the study revealed the positive effects of Alliance VF tyres in comparison to conventional ones. The test was conducted on a tractor-trailer combination and the low inflation pressure of the Agriflex+ 372 (tractor) and Agriflex+ 389 (trailer) cut the track depth during the application of liquid manure in half. At the same time, wheel slip was reduced by 4,4%, and measurements with a penetrometer showed lower soil compaction in the ‘VF tyre tracks’ in the soil zone from 0 to 40 cm.

Furthermore, maize yields in the tracks on ‘VF tyre plots’ exceeded those of the tracks on the ‘conventional tyre plots’ significantly by about 12.9 harvest units per hectare, i.e. by about 10 percent.

The conclusion was clear: thanks to Alliance VF technology the results translated to yield increase between 1.5 and 2.2% per hectare and calculated profit gains due to higher yields and reduced tyre slippage of up to almost 80 EUR per hectare.
