Tractomas the world’s largest semi-truck which is capable of pulling a road train weighing 535 tonnes, is fitted with 385/95R25 Goodyear GP-2B tyres.

The truck, built by French heavy-haulage vehicle specialist Nicolas, has been ordered by mining company LCR and will operate pulling a train of side-tipping trailers at a lignite mine in the Australian state of Queensland.  The Tractomas TR 10×10 has an unladen weight of 40 tonnes, is 10 meters long, 3.5 meters wide and 4.6 meters high.  It is powered by a 27-liter Caterpillar diesel engine, which develops 1000 hp and will propel the tractor and trailers with a total train weight of about 535 tonnes at a speed of up to 50 km/h over distances of up to 40 kilometers.

The Goodyear GP-2B is a multi-purpose 100 level tyre, most commonly used on mobile cranes for off road operations.  It is a long-wearing radial tyre offering a high level of lateral traction in demanding conditions and a smooth ride on hard improved surfaces.  Its open shoulder grooves provide outstanding self-cleaning characteristics. The size mounted on the Tractomas is 385/95R25.
