The Alliance 506 Dual Masters' dual sidewall structure allows for close contact between two tyres, without the need for a special rubber ring to prevent stone penetration between the tyres. The radial structure of the tyre ensures a long tread life, comfortable driving, and low fuel consumption. Its robust all-steel casing ensures machine stability, good puncture protection, and tyre retreading. The shoulder lugs provide effective grip on soft surfaces. Additional rubber around the central line allows for a flexible and stable behaviour on hard surfaces.
