AGG1 debut for new Bridgestone quarry tyre
MASTERCORE V-Steel Rock Deep Ultra (VRDU) tyre offers enhanced load capacity and more tyre life
BRIDGESTONE Americas will be introducing the 27.00R49 V-Steel Rock Deep Ultra (VRDU) aggregate tyre at the Aggregate Academy & Expo (AGG1) in St. Louis, Missouri, from 25–27 March 2025. The VRDU is the first aggregate tyre engineered with the company’s groundbreaking MASTERCORE technology, bringing the proven performance and tyre life of the product line-up to the aggregate segment.
‘Bridgestone’s MASTERCORE technology epitomizes how our company helps customers move more with less,’ said Rob Seibert, president of off-the-road tyres at Bridgestone Americas. ‘With the new 27.00R49 MASTERCORE VRDU, we’re adapting our proven technology from the mining segment to the aggregate industry, offering enhanced durability, performance, and value across a wider range of applications.’
The Bridgestone MASTERCORE VRDU, which is specifically designed for rock surfaces, will be offered in four advanced compounds engineered to deliver performance tailored to the unique needs of each quarry operation. Designed for dumptrucks, the new tyre comes with several special features to help deliver greater efficiency:
Deeper tread depth – The tread pattern of the VRDU boasts a 35% deeper tread depth. It is designed to provide haul trucks with superior traction on rocky terrains, as well as better stability and comfort
Improved tyre life – The MASTERCORE VRDU’s deeper tread pattern incorporates innovative cooling slopes and centre grooves to help extend tyre life by 26% compared with the Bridgestone VRLS
Increased load capacity – The proprietary casing is engineered with MASTERCORE technology, which uses a wide and strong belt package and rubber compounds. This delivers up to 10% more load capacity versus Bridgestone’s conventional tyres and key competitors.
The MASTERCORE VRDU will be manufactured at Bridgestone’s Aiken County off-the-road (OTR) plant to support growing industry demand in the US and Canada. It will be available later this year.
