A: Lower rolling resistance, better fuel economy, reliability and longer mileage have always been important to Marangoni, that’s why these performance characteristics were designed into the unique RINGTREAD System and sets it apart from conventional retreads.

“Instead of making small, incremental changes to flat, spliced retreads, Marangoni completely departed from conventional precure retreading by inventing the RINGTREAD System. The result is more miles and better mileage.” Giuseppe Marangoni

The RINGTREAD is designed round, not flat, and without a splice to fit the tyre just as it should.
Not only did the RINGTREAD® System remove the technical problem of the splicing of treads, the system was ahead of it’s time in the introduction of contour shape tread technology. Typically RINGTREADS produce 20% more miles and 1 to 3% better fuel economy that conventional flat treads.

Unlike conventional precure retreading, where flat tread rubber is wrapped around a buffed tyre casing and the tread ends are spliced together, the precured Marangoni RINGTREAD® is molded in one piece in circular molds so that it fits the contour of the round tyre and eliminates the splice. This superior design eliminates the distortion and deformation of the rubber that occurs in conventional flat precure retreading.

The result is a uniform, better-balanced retreaded tyre, which yields longer lasting, even tread wear that requires less energy to roll and is cooler running. RINGTREAD® users report the lowest cost per mile of any retread product in the marketplace.
Marangoni achieves this lowest cost per mile benefit for its customers with their RINGTREAD® product for several reasons:

1. The contour shape of the tread matches the round shape of the tyre; flat tread does not naturally fit the round casing. A traditional flat-tread design causes tread distortion when applied to a round casing therefore resulting in reduced mileage. RINGTREAD® allows maximum tread adhesion, preserves casing integrity, eliminates stress between tread and casing and runs much cooler.

2. A conventional flat tread requires splicing and the tread pattern is subject to being mismatched and distorted. This practice results in a heavy spot at the splice, creating an unbalanced condition and the possibility of a splice failure. Because RINGTREAD® is a continuous ring, it is uniform all around and this results in a uniform tread pattern and new tyre appearance.

The RINGTREAD® System delivers perfect fitment and even wear. With its no-splice installation and laser-guided centering on the casing, the end result is a truly balanced retread. Because of it’s improved performance RINGTREAD can deliver more miles with a shallower skid depth thus reducing further rolling resistance improving fuel economy and extending casing life.
Since first designing and developing the RINGTREAD® system, Marangoni has continually improved on the design and today the Marangoni RINGTREAD® outperforms competition due to it’s superior design and the quality control in the manufacturing process.

Since it’s introduction 27 years ago, the RINGTREAD® System, the retreading process developed by Marangoni Tread, Verona, Italy using a splice-less tread ring cured in a circular mould, has been viewed in the retreading world as a major innovation that is still revolutionizing the industry today
