GT Radial's first specific winter-marked tyre, the GSW226, has been expanded by three new sizes to target coach operators, hauliers and gritter fleets which need to meet UK and trans-European winter road regulations.

The high-traction steer and trailer axle tyres are both three peak mountain snowflake (3PMSF) and M+S marked and are now available in 315/70R22.5, 315/80R22.5 and 385/55R22.5 sizes. Load indexes range from 152/148 M to 158 L (160 J).

The tyre is designed to cope with severe winter conditions including snowy, icy and wet roads. It has a wide shoulder groove to deliver optimum handling and stability and uses a new advanced compound for high mileage potential.

Tony McHugh, TBR sales and marketing director UK at Giti Tire, said: 'This is an important development in the portfolio as it opens up a number of new markets, primarily in countries where 3PMSF symbols are required by law but also for those operators who simply want a solid, accredited winter option.'
