MASTERCORE VRDU
V-STEEL ROCK DEEP ULTRA
In quarry operations, success depends on solutions that maximize efficiency while enduring a range of harsh conditions. That’s why Bridgestone is proud to introduce the new V-Steel Rock Deep Ultra (VRDU) tire, our latest 49” innovation and the first of its size to feature Mastercore technology. Designed to elevate the output of 100-ton rigid dump trucks on rocky surfaces, the MasterCore VRDU tire offers up to 35% deeper tread depth², 26% longer tire life³, and 10% more load capacity¹. Bridgestone MasterCore VRDU is offered in four advanced compounds to deliver performance tailored to the unique needs of your quarry. E1A (Standard), E2A (Cut Resistant), E2A LS (Ultra Cut Resistant) and E3A (Heat Resistance)
