BKT Agrimaxfactor tyres in sizes 600/70 R 30 and 710/70 R 42 have successfully passed DLG’s rigorous evaluation process.
The ‘DLG Approved’ Quality Mark is a Testament for BKT’s R&D Process
Leading multinational off-highway tyre manufacturer, BKT, has gained the quality mark from the independent institute DLG for the second time. The BKT Agrimaxfactor tyres—in sizes 600/70 R 30 and 710/70 R 42—have been awarded the “DLG Approved” quality mark after having successfully passed a rigorous evaluation process.
“Once again, BKT products have proven to be key players in the segment, distinguishing themselves from the competition by means of their high quality and outstanding performance, now also recognized by a trend-setting institution such as DLG,” said Lucia Salmaso, the Managing Director of BKT Europe.
“Having gained, for the second time in a year, the ‘DLG Approved’ quality mark is a further confirmation of BKT‘s strong focus on the entire research and development process, as well as synonymous with meticulous design development that prioritizes farmland preservation and emission reduction,” she added.
The primary objectives of the tests conducted by DLG included an analysis of the tyres’ effect on the soil and fuel consumption. These are considered the key factors nowadays when it comes to ensuring environmental sustainability and cost optimisation in the farming sector.
The tests were conducted in two different phases: Field tests on farmland under comparable operating conditions, and simulation tests of transport activities on both slope and level ground on a DLG dynamometer test stand. The test was performed as DLG PowerMix simulated real transport conditions on paths at different inclinations. The testing procedure enabled the measurement of parameters such as specific fuel consumption, performance at constant speeds, and overall tyre efficiency under controlled conditions.
The BKT Agrimaxfactor tyres were compared against five competitors. The tests were conducted in March 2024 using a John Deere 6R 250 tractor and a Claas Xerion as the braking tractor. The measured ground pressure values highlighted a clear correlation between the contact area and the penetration depth. At all measurement depths (10, 20, and 40 centimetres), the BKT Agrimaxfactor achieved the best results; the lowest ground pressure value of 0.13 bar is recorded at a soil depth of 40 centimetres and a tyre inflation pressure of 0.6 bar.
The low pressure on the contact area, which on average produces a measured track depth of 7.1 centimetres, reflects the BKT tyres’ ability to generate a depth of just 6.5cm—8% below the average value and 18% less than the last-placed competitor.
Another key point is fuel consumption. During the field tests, BKT tyres recorded a 1.7% lower fuel consumption than the average (17.4 l/ha), while the consumption in the transport tests was 0.3% below the mean value of the reference tyres. Specifically, in the 40-km/h variant of the DLG PowerMix transport test, the Agrimaxfactor tyres sized 600/70 R 30 and 710/70 R 42 recorded a specific consumption of 367 g/kWh, whilst in the 50-km/h variant consumption increased to just 372 g/kWh.
