Marangoni Retreading Systems, tirelessly pursuing technological development and striving to constantly anticipate the needs of the tyre retreading market, has accepted another new challenge: the design and production of new generation RINGTREADS that will overcome the age-old incompatibility between high mileage and grip.
The first new generation RINGTREAD is the tried-and-tested RDG100, available for retreading Series 70 and 80 tyres.
The profile, the first original Marangoni pattern, is designed for use on drive axles on vehicles that mainly travel on regional, national and international routes.
An all season and multipurpose pattern, featuring a wide footprint to make it easier to adapt to continuous changes in the weather and road conditions during operation. The special “interlock” siping on the tread blocks ensure excellent control on wet, snow-covered and icy surfaces. This modern dimensional siping, as well as being deeper, gives the all season tread high resistance to tearing and very regular wear.
The innovative pattern is created using a completely automated process, extruding the rubber directly into the moulds, for perfect uniformity of the final product.
The profile is currently available for 315/80R22.5, 315/70R22.5 and 295/80R22.5 size tyres.
The range has been designed to provide specific solutions for different road conditions during the winter, a combination of wet, dry and snow-covered surfaces typical of central Europe. This range of new generation tread profiles consequently combines excellent performance on snow and ice with exceptional traction and high mileage.
RINGTREAD is the only retreading system that uses joint-free precured rings that adhere to the casing without tension or deformation of the tread pattern, ensuring high traction on tough surfaces due to the greater precision and directional stability of the siping and blocks.
Moreover, the range is made using HP compounds suitable for low temperatures that ensure the best possible grip on the tricky surfaces that are typical of winter. The main advantages that come from using these special compounds include better elasticity at low temperatures and reduced rolling resistance, as well as longer life of the rubber on the tread in more stressful conditions. These compounds also allow the tyre to work at lower temperatures in operating conditions that cause overheating, ensuring reduced casing fatigue and longer life.
