The new 33.00 R 51 size tyre is designed for rigid dumpers operating under adverse conditions in rocky environments such as quarries, mines, dams, and the construction sites of large building structures.
Earthmax SR 46 weighs 2,400kg and BKT says the new tyre is particularly suitable for transporting heavy loads, adding that its cut-and-chip resistance extends the product’s life.
The company says that impacts, mechanical stress, and punctures are reduced to a minimum due to the steel-belted casing, which optimises operating hours and maximises productivity.
The Earthmax SR 46 also features a special tread design showing a block lug pattern with circumferential grooves, which is designed to reduce external wear and produce excellent cornering performance.
BKT says that the entry of the new large size into its tyre line-up is a strategic choice that is in line with the trend for increasingly larger machines.
“We have been working on our radial OTR [off the road] range since it was launched in 2008, and the objective since then was to enter the giant tyre sector,” said BKT managing director Lucia Salmaso.
She added that the Earthmax SR 46 is predominantly aimed at large mines and quarries in territories including Asia, Africa and Australia.
In the first three months of 2020 the company plans to launch a 4m tyre that will also target the large mine and quarrying sectors.
