A new size is available in the Goodyear RH-4A+ range of off-highway haulage tyres. The addition of a 40.00R57 product increases the number of available dimensions to four.
Initially launched last autumn, the Goodyear RH-4A+ is engineered to deliver a lower operating cost per hour and higher productivity in hard rock underfoot conditions.
Goodyear says the tyre provides the following benefits and features:
• Increased hours to removal with its high net-to-gross tread pattern and extra-deep E-4+ tread depth.
• Cool operating temperatures from the tread’s centreline blading, shoulder lug pockets, and shoulder lug side notches.
“The 40.00R57 has become Goodyear’s dominant fitment on 200-tonne trucks, such as the Caterpillar 789,” says Eric Matson, Goodyear Tire & Rubber’s global OTR field engineering manager. “With a higher TKPH and load carrying capacity, the new Goodyear RH-4A+ tyre size is a great option for customers who have converted their 789 fleets to this larger tyre.”
The Goodyear RH-4A+ is now available in sizes 40.00R57, 59/80R63, 46/90R57 and 27.00R49 through Goodyear’s global network of authorised OTR dealers. It is available in customised casing constructions and is made with Goodyear’s proprietary tread compounds.
