‘World’s largest’ agri tyre to debut at Agritechnica
Amongst the exhibits at the upcoming Agritechnica show in Hanover, Germany will be the largest agricultural radial ever produced. This behemoth of the farm is Firestone’s new DT23 in size IF850/75R42. Manufactured by Firestone in the USA, the giant DT23 is designed for the latest generation of 500 plus horsepower heavy tractors. With an overall diameter of 2.32 metres, the DT23 has an 850/75 section/aspect ratio and rim size of 42 inches (107 centimetres). It weighs 510 kilograms and has a load capacity of 9.5 tons at speeds of up to 50 km/h when inflated at 1.6 bar.
“As larger farm operations grow in Europe, farmers are looking for more efficiency from their machinery,” commented Rafal Spirydon, senior manager AG Sales & Marketing, Bridgestone Europe. “The Firestone DT23 is designed to maximise the performance and efficiency of today’s most powerful tractors.”
The DT23 employs Firestone’s new AD² “Advanced Deflection Design” technology, which the manufacturer says allows the tyre to carry a higher load, with a larger footprint than standard radial tyres. This larger footprint in turn offers improved traction, which leads to less time in the field and reduced fuel consumption; reduced soil compaction, which is especially valuable with heavier machinery; and a greater load capacity compared to standard radials at the same inflation.
