New Bridgestone VJT tyres for loaders and ADTs

The new tyre range is readily available in a range of sizes for loaders in the 10-30 tonne range and articulated dump trucks with operating weights of 20-35 tonnes.
It provides a number of benefits, including improved higher machine productivity operator comfort, longer tread life, full traction in both forward and reverse, and increased resistance to sidewall cuts compared with Bridgestone’s VMT tread pattern.
According to Paul Comninos, Bridgestone Earthmover Tyres’ senior manager, engineering services, the new VJT range is designed to deliver higher productivity, particularly in loading applications.
“Ideal for wheel loader operations, our VJT tyres have an innovative non-directional tread patterns - ensuring the same high traction moving forward or backward - for extra rimpull and productivity,” he said.
“In addition, a larger tread volume compared with the VMT design results in significantly slower wear rates.
“This larger tread volume and slower wear rate gives extended tyre life.”
The VJT tyres’ sidewalls have been shaped to minimise damage from cutting, with cut resistance further enhanced by protectors to guard against tears and cuts due to heavy loads, said Comninos.
“The new design also features more rigid sidewalls, meaning fewer sidewall cuts - again increasing tyre life - but also reduced vibration, for greatly improved operator comfort.
“Bridgestone’s tyre design engineers have paid particular attention to reducing vibration - and therefore increasing operator comfort - through the use of two separate reinforcement systems designed to provide extra-low vibration,” he said.
“The left and right centre blocks on the tread surface are connected by two tie-bars, which also increases centre-block strength for enhanced wear resistance.
“As well, double-reinforcement tie-bars minimise the centre blocks’ longitudinal elongation and deformation upon surface contact, reducing friction between the centre blocks and the ground, minimising irregular block wear and extending tyre life.
“And as the tyre travels along the ground, two specially designed vertical columns of centre tread blocks keep vibration at minimum levels,” said Comninos.
“Together, these translate to lower costs per hour or kilometre, through longer tyre life, as well as reduced downtime through fewer tyre changes.”
Bridgestone’s VJT tyre range is available in a range of sizes, including 20.5R25* (loader only), 23.5R25 MS* and 26.5R25 MS* (loader and articulated dump truck).
