Since I’ve had Cooper ST Maxx tyres fitted I have done two leopard rescues one in very muddy terrain after a heavy rain. I was nervous. I know the area well and know it’s best to deflate but I decided not deflate as I needed to get to the leopard quickly as she had been caged for three days. The tyres were phenomenal – they just throw the mud away. I managed to get through and collect the leopard. On the way to the release site I experienced completely the opposite terrain – very rocky, tough terrain with some climbs tackled in reverse and always in 4x4 low. The tyres never lost grip – they performed beautifully and the leopard was successfully released. A real advantage is the lack of road noise. I can now take calls in the bakkie and hear the caller. Hands free, of course. ...read more

There is now a tyre constructed and designed to thrive in South Africa’s harshest conditions, while still offering great on-road characteristics.

Super Tensile Steel Belts

15% stronger than high tensile steel’ which results in higher impact strength and puncture resistance.

Proprietary Cut and Chip Resistant Tread Compound

Provides improved wet and dry traction and handling on the highway, while also improving cut and chip resistance in harsher rocky and gravel terrain.

Enhanced Traction on wet and greasy bitumen

Micro-gauge sipes help reduce the potential for stone retention and stone drilling into the tread elements. They also enhance traction on wet and greasy bitumen.

Maximises Grip

The proven Y-block tread pattern and optimised draft angle together maximise (on- and off‑ road) grip and provides remarkably low noise for a tyre of its class.

Minimising Damage

Self-cleaning shoulder scallops maximise off‑road traction, while minimising abrasion and damage to the protruding lugs, giving you a longer-lasting tyre.

Great Off-Road Traction

The enhanced buttress design provides additional off‑road traction, abrasion resistance and a rugged appearance.

Extra Resistance to Cutting and Chipping

Stone ejector ribs and raised-centre-groove varied channels in the shoulder area resist damage by discharging stones which cause stone drilling. Raised centre groove prevents foreign objects from lodging into the tread, giving you extra resistance to cutting and chipping.
