Balancing the books without compromising on the fundamentals of passenger and personnel safety is one of the challenges that all businesses dealing with passenger transport and operating fleets of coaches need to face, especially in these hard economic times. One excellent way to meet these demands is to fit good retreaded tyres such as the new Marix MD Extra. On coaches that travel intercity routes, cost savings of around 40% can be acheived when compared to similar new tyres – all without losing out in terms of quality.
Made specifically for the drive wheels of intercity coaches, Marix MD Extra is a universal 295/80 R22.5 drive tyre that guarantees maximum performance all year round and in any weather. A five-groove tread with specific block sculptures and longitudinal channels guarantees maximum grip in all road conditions, good stability, quick and effective water drainage and excellent road hold throughout the tyre’s life. All obviously without neglecting the economic aspects, given that Marix MD Extra ensures very high mileage.
Then add in the fact that the tyre is manufactured by a company like Marangoni, which for over half a century has been synonymous with retreading, and the result is a product made with maximum technical skill. For bus and coach tyres, for example, Marangoni designs specific compounds than can satisfy all the various requirements: resistance to twisting forces exerted on the tyres when changing direction in tight spaces and when steering at a standstill, resistance to impact on the tyre sidewalls, as well as chafing and abrasion, and low rolling resistance meaning a significant reduction in fuel consumption.
From a quality point of view, modern retreads feature performance that’s comparable to that of new tyres. Since 2006 retreads for buses and coaches need to be UN ECE 109 approved, in other words they have to pass the same tests applied to new tyres to verify their sturdiness, reliability and working life. Marangoni obtained such approval in 1999. The use of retreads also represents an important contribution to safeguarding the environment, allowing casings that are still intact to be reused even two or three times. A solution that’s both ecological and economical, as already testified by municipal transport companies in large Italian cities such as Milan, Turin, Genoa and Verona. These companies trust Marangoni, knowing they can count on a custom retreading service that, among other things, includes technical support and specific consulting for the choice of the most suitable tread pattern.
The Marix brand, introduced by the Marangoni Group several years ago to denote retreads for cars, light commercial vehicles and 4x4s, will soon be used for all retreads manufactured by the Rovereto company and consequently also for tyres to be used on industrial vehicles, quarry and site machinery, buses and coaches and earthmoving equipment. The retreading process implemented at the Marangoni facilities in Rovereto to produce the Marix tyres has for some time now included the most advanced quality procedures at all levels. As well as compulsory approvals, Marangoni has achieved various certifications such as ISO 9001:2008 for quality and ISO 14001:2004 for environmental management.
