At 3.5 metres in height the BKT EARTHMAX SR 468 is the biggest tyre the company has ever produced
Launched on the market in 2021, the EARTHMAX SR 468 is designed for rigid dump trucks and will be exhibited in the size 40.00 R 57, corresponding to a height of 3.5 metres, a width of 1.13 metres and with a weight of 3,800kg.
Suitable for operations on rocky and harsh terrains, EARTHMAX tyres are designed to be particularly resistant to impacts and punctures thanks to an all-steel structure that provides resistance to the casing.
In addition, an E-4 tread depth offers extreme resistance in severe conditions. In addition, the specially designed tread pattern and the tread compound have been specifically developed to reduce heat generation during these types of extreme applications.
The BKT EARTHMAX range is designed to provide a better weight distribution on the ground for dumpers, wheel loaders, dozers, graders and some multipurpose vehicles.
The range includes 40 different tyres for the earthmoving, construction, mining and quarry sectors and is available in many sizes and different compounds.
BKT is working on many fronts in the OTR tyre sector, with a particular focus on compounds that are highly cut-and-chip resistant as well as on ultra-heat-resistant compounds that are capable of carrying heavy loads while maintaining an excellent TKPH (i.e. the average ratio between the transported weight by the equipment and the speed in kph).
This is how tyres in the BKT EARTHMAX SR 46 range stack up – the SR 46: 33.00 R 51 and 27.00 R 49 with a diameter of over 3 and 2.6 metres respectively
