Casumina GS621
All-steel TBR tyre imported straight from the factory. Fixed price in the pre-sale.
Reserve tyresGS621 is the backbone of the Greenstone line and the pattern most relevant to Icelandic haulage. It comes in both 315/80R22.5 and 295/80R22.5, the two most common fitments on tractor units and trailers here. The tread is a clean rib pattern with three even ribs down the centre, which holds the vehicle straight and keeps rolling resistance down over long runs. Staggered jagged grooves with multiple sipes clear water and eject stones rather than trapping them. A wide tread face and seamless shoulders reduce irregular wear, the most common reason steer tyres come off early.
