Marangoni Presents Renova in Italy
Austrians Successful in the Snow
Marangoni has relaunched its own brand of retreaded truck tyres. The Renova brand has been developed to meet the needs of cost-containment and reliability through the reconstruction of tyres aimed at the middle market.
As is well known to experts, the quality and availability of carcasses is one of the most important elements for the development of the retreading industry. The ability to make the most of this important resource, however, is linked to the ability to retread properly on casings selected for their integrity and quality subject to their future use, using materials and processes that meet these requirements.
A company that specialises, as Marangoni does, manages to bring out the best in terms of performance (mileage, rolling resistance, grip etc.) in sub-premium casings, which are
still retreadable if properly processed and if matched with suitable materials.
Thanks to its expertise in the industry, Marangoni is now able to offer an entry level range with Renova, that allows the company to meet the needs of all users. So, the Marix RP 100 offer a premium product for those with high demands on performance and reliability, the Renova range places Marangoni also in the market with budget level retreaded truck tyres. The Renova range offers classic tread patterns suitable for the most common uses.
The use of shearography ensures that only the best of casings are utilised for retreading for both the Marix and Renova ranges. Renova is available as either a hot cure or a cold cure retread depending upon the tread pattern and size.
Not only do their top winter athletes demonstrate year in year out that Austrians know how to handle snow. Germany's neighbour is also up front as far as good snow retreads are concerned. Five Kraiburg designs have now proven this impressively in a winter suitability test: K213, K204, K225, K700 or K74 – all show more than 25 per cent better traction than the reference tyres (KDA2e). Kraiburg
sets on standard/reference rims prior to the individual tests and balanced them and inflated them to the required standard pressure. The tyres fitted to the test vehicle were tested 6 times in every dimension and every tread. The single wheel was loaded with 75 per cent of the load index for individual use.
To ensure reproducibility, the tyre experts conducted the measuring
Austria carried out the tests together with the North Test
L a b o r a t o r y.
The test procedure was based on the draft of ECE-117 R for tyres of class C3. The air temperature was a constant 2.5 degrees Celsius, the snow thermometer showed minus five to six degrees Celsius and the snow covering was about 40 millimetres deep. The retreading specialists fitted the five truck tyre
series twice with the reference tyres first. Then came the truck tyres with the above named winter retreads. Six test runs were recorded and then the average calculated for every tyre set. The measurements describe both the rear wheel and four-wheel drive. The Kraiburg retreads proved their traction capability on a stretch with an uphill gradient of up to 23 per cent at a speed of eight km/h.
Marangoni Upgrades Winter Range
Marangoni Retreading Systems is pleased to present its updated range of cold-retreaded winter tyres; the lines have been extended and completed so as to cover all needs: from all-season profiles to patterns suitable for wet roads, snow and ice.
The Marangoni winter range has been designed to provide specific solutions for the different road conditions typical of winter, from the combination of wet, dry and snow-covered roads typical of central Europe, to the more complicated
conditions that are so easily found in Nordic countries. Bringing together excellent performance on snow and ice and exceptional traction, the range covers both regional and long distance applications.
The profiles have been developed using high performance compounds suitable for low temperatures that ensure the best possible grip on typically tricky winter surfaces. The main benefits of using these special compounds include better rebound at low temperatures and
