R4(Apertures) tread pattern tires, with the big tractive lugs and wider contact area, are versatile and known as the ATU (All Traction Utility). Featuring the improved rubber compound for greater resistance to cutting and the sidewall apertures designed for heat dissipation and softer ride equivalent to the foam filled pneumatic tire, our R4(A) tires have the ability to absorb considerable punishment from the tough terrain effortlessly and they are perfect suitable for wheel loaders, skid steers, telehandlers, reach stackers, material handlers, backhoe, mining machines and other industrial vehicles.
