About Marangoni
Marangoni S.p.A. is an Italian manufacturer headquartered in Rovereto that has been active in the tyre sector since 1945. The company operates in four business areas: Retreading Systems (materials and technologies for the cold retreading of truck tyres using the RINGTREAD system with prefabricated, splice-free tread rings), Tyre Machinery (development and construction of retreading machinery for passenger car, truck, OTR and aircraft tyres, 90% of which is exported), Tyres and Services (production and direct distribution of retreaded TBR and OTR tyres as well as fleet management) and Technical Compounding (custom rubber compounds for industrial applications). Processes include cold retreading with precured tread rings up to 450 mm in width, hot retreading, OTR retreading up to 63 inches, aircraft tyre retreading from 10 to 28 inches, and solid rubber tyres. The group employs around 1,000 people and maintains production and distribution sites in Europe, North and South America, Africa and Asia.

Materials and Processes
Rubber compounds (technical compounds)
Traditional and special rubber compounds for retreading and industrial sectors, partly custom-made.
Cushion Gum
Extruded adhesive compound applied during the building process to the carcass and shoulder.
Precured tread rings (RINGTREAD)
Splice-free, precured rings for the cold retreading of truck tyres, up to 450 mm in width.
Precured tread strips
Material for cold retreading, including from the acquisition of Ellerbrock (Hamburg).
Polyurethane foam
Tyre filling for industrial tyres, e.g. forklift tyres, for puncture protection.
Steel (steel cord)
Tyre steel as a raw material; retreading saves substantial amounts of rubber and steel.
Solid rubber
Material for solid rubber tyres for industrial applications (in production since 1986).
