The tyre features Goodyear's new Durawall Technology, which aims to improve sidewall durability and lateral stability, and has a wider bead design and moulded rim width.
Field trials with mining customers using the 46/90R57 model showed that these features enable to the RH-4A+ to deliver up to 12% better hours to removal than its predecessor.
"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," said Matson.
The RH-4A+ is currently available in sizes 59/80R63, 46/90R57 and 27.00R49, noted the company.
