Alliance held its first Field Day in eastern Germany on 26 August 2026, with support from Bohnenkamp SE and its partner AGRAVIS TECHNIK, with farmers and agricultural professionals from the region participating in four live stations that turned tyre technology into practical decisions.
Field Day Demonstrations
During the first Alliance Field Day in Eastern Germany, the demonstrations focused on managing sprayer tyre pressure correctly with Alliance Agriflex+ 354 VF tyres, pulling force in relation ty tyre pressure with Agriflex+ 372, soil compaction and footprint with Agriflex+ 372 and the effect of pressure on slip and operating costs with Agriflex+ 373.
An agricultural sprayer equipped with Alliance Agriflex+ 354 VF tyres showed why inflation pressure should be based on the machine load, operating speed and work being carried out. Alliance specialists explained how weighing a machine and consulting the tyre load table provides the basis for an appropriate setting instead of relying on a single pressure for every task.
Reducing road pressure to the correct field setting allows a tyre to lengthen its footprint and distribute the load over a larger area. Compared with a conventional radial tyre of the same size, VF technology can carry the same load at up to 40% lower pressure or up to 40% more load at the same pressure.
A pulling-force demonstration using Alliance Agriflex+ 372 tyres showed how pressure changes the way a tyre engages with the ground. Excessive pressure reduces the footprint, while too low pressure can cause the centre of the tread to collapse inwards. The correct setting helps the tread work effectively across its width, transferring more power into forward movement.
“Tire pressure is not a single setting that suits every operation. It needs to reflect the axle load, operating speed and work being carried out. When these factors are matched correctly, farmers can put more power into forward movement, reduce soil stress and make better use of both the machine and the tyre, ” explained Gerrit Vinkers, Field Service Manager Europe at Alliance.
At the soil station, a prepared profile made the effects of tyre footprint visible below the surface. Contrasting layers in an excavated pit showed how machine load is transferred into the ground when equipment fitted with Alliance Agriflex+ 372 tyres passes over it.
The demonstration showed why the surface track alone does not tell the whole story. Deeper compaction can restrict roots and disturb the balance between soil, air and water. A larger, correctly developed footprint distributes the load more evenly and can help protect the soil structure on which future yields depend.
A fourth station used Alliance Agriflex+ 373 VF tyres to connect pressure and footprint with wheel slip, fuel consumption and cost. Unnecessary slip means that engine power and fuel are being used without producing equivalent forward movement. Setting pressure correctly for the implement and conditions can therefore support both field performance and operating efficiency.
“Especially on large-scale farms in eastern Germany, choosing the right tyres is a key factor in maintaining soil health. Tyre pressure should be adjusted for each task and kept as low as the load and operating conditions allow. Proper ballasting is equally important: only as much additional weight should be carried as is actually needed for efficient traction,” said Stefan Vogelsang, farmer and agricultural content creator.
Alliance and Bohnenkamp SE also presented agricultural and transport tyres and discussed applications directly with visitors. AGRAVIS TECHNIK contributed regional machinery expertise and supported the working demonstrations.
