engineered for ultra-high durability , based on a combination of unique technologies that include a new type of steel cord and other advanced materials , structure and process engineering .” Below are key features of MasterCore tyres : n An industry first , MasterCore tyres are engineered with steel cord that features Metal Surface Coating Technology for improved adhesion between the rubber and steel cord , delivering better durability . n MasterCore tyres utilise proprietary anti-rust steel cord developed and manufactured by Bridgestone for added moisture resistance that improves durability . n Designed with new rubber compounds for improved crack propagation , MasterCore tyres have an enhanced casing for more dependable performance . n MasterCore tyres have new patterns and features that reduce tyre operating temperature for better performance . Mine operations vary by customer , mine site and haul route , which is why Bridgestone says it designed MasterCore tyres for customised performance . MasterCore tyres can be optimised for a number of performance attributes including faster speeds , increased payload and maximised uptime . Bridgestone began testing MasterCore tyres with select customers last year and says performance has exceeded customer expectations .
“ Bridgestone is developing advanced mining solutions to meet customer needs and deliver social value . The company ’ s mining solutions offering includes Dan-Totsu ( clear and absolute leader ) products such as MasterCore , best-inclass service delivered by Bridgestone solutions engineers who are experts in mining tyres , mining solutions centres and the company ’ s iTrack solutions business . Bridgestone is leveraging its solutions business to improve resource productivity by combining the real and digital worlds to deliver integrated products , services and servicing networks that utilise tyre and mobility data .”

Goodyear RH-4A + for long hours & hard rock conditions
The Goodyear Tire & Rubber Company has announced its own newest addition to its offhighway large haulage product line , the RH-4A +, engineered to deliver a lower operating cost per hour and higher productivity in hard rock underfoot conditions . This tyre features an extradeep E-4 + tread depth with a high net-to-gross tread pattern and optimised footprint pressure to help provide long hours to removal . The Goodyear RH-4A + tyre is an important addition to Goodyear ’ s Total Solution of trusted products , reliable services and fleet management tools – all delivered by a global network . The new Goodyear RH-4A + large haulage tyre it says helps operators be more productive and operate at a lower cost by providing the following benefits and features : n Enhanced sidewall durability and lateral stability with Goodyear ’ s new Durawall Technology ® , wider bead design , and wider molded rim width n Increased hours to removal and cut protection with its high net-to-gross tread pattern and deep , E-4 + tread depth n Cool operating temperatures from the tread ’ s centerline blading , shoulder lug pockets , and shoulder lug side notches Field results from global mining customers have shown that the RH-4A + delivers up to 12 % better hours to removal than RM-4B +. “ Low operating cost per hour is an important requirement for mine operators ,” said Eric Matson , Global OTR Field Engineering Manager . “ Customers also require other performance benefits , such as a tread and casing that together deliver long hours to removal , resistance to cutting , and excellent traction in severe , hard rock underfoot conditions . The new RH-4A + provides these benefits to help mining fleets optimise productivity and lower their operating costs .”
The RH-4A + is currently available in sizes 59 / 80R63 , 46 / 90R57 and 27.00R49 through Goodyear ’ s global network of authorised OTR dealers . It is available in customised casing constructions and with Goodyear ’ s proprietary tread compounds to meet hauling conditions .
“ Complimenting the RH-4A + is Goodyear ’ s EMTrack tire performance tracking software , giving operators the ability to track the tyre ’ s properties to reduce operational costs ,” said Matson . “ With EMTrack , mining operators can track the performance of their tyres , including the new RH-4A +, in order to project timing of rotation , replacement and help to manage their inventory .”
