No Brasil a Portaria 554, do Inmetro e a Norma da ABNT NM 225 é que determinam a vida útil dos pneus para reforma. No caso de pneus destinados a veículos comerciais, comerciais leves e seus rebocados, não existe impedimento de tempo, desde que tenham condições ideais para a reforma podem ser reformados. Pneus novos, tem validade que é geralmente o que determina para a garantia.
Os pneus que não são mais úteis para a empresa devem ser destinados através de Ecopontos. Pode localizar o mais próximo no site http://www.reciclanip.org.br. A legislação que define as responsabilidades da destinação de pneus inservíveis é do CONAMA, n° 416/09 no Art. 1° Os fabricantes e os importadores de pneus novos, com peso unitário superior a 2,0 kg (dois quilos), ficam obrigados a coletar e dar destinação adequada aos pneus inservíveis existentes no território nacional, os locais de coleta é através de Ecopontos conforme informado.
Commom causes may be due to mechanical problems, misuse or tyre defects. It is always important to carefully evaluate the causes and treat them to avoid recurrence and consequently further damage to the tyres and vehicle.
The ideal pressure calibration is based on a few factors. The variables include the type of route, weight of the load, variable of the empty/loaded route. For commercial vehicles, it is common to find load variation; this item is the main requirement for setting the correct pressure. It is common to find cases that use the pressure described on the side of the tyre; however, this pressure is the maximum recommendation for the maximum load. If there is a significant weight variation in the same fleet (container transport and rock transport), there will be a need for different pressures per route and/or vehicle; To define this, it is necessary to know the weight per axle, and make calculations and evaluations on the tyres. So we recommend you to reach Vipal team, who will guide you in these calculations and definitions. The verification must be done frequently. Besides defining the ideal tyre calibration, it is necessary to check if the whole set has adaquate pression.
Brazilian legislation only prohibits the use of retreaded tyres on the front axles for the transport of passengers and hazardous cargo. In other applications, use is permitted.
Emergency repairs, if not replaced, may cause infiltration and may lead to tyre refusal during the retreading process.
Permanent repairs are all safe. However, it is important to choose a qualified professional who knows how to choose and apply the correct repairs. All Vipal retreaders are prepared to apply the appropriate repair for the damage on the tyre.
Emergency repairs as well as poor quality repairs can make retreading unfeasible. Ideally, the company will only use the spare tyre while on the road and all repairs will be made in the fleet or retreader that serves them.
The repair must always be done definitively, with repairs that fill the hole and cover the damaged area (hole). The objective is always to prevent the chance of infiltration, and some solutions are to: - Fix with cold cure patches - Plug applied with cold glue or maybe a plug to cure the region of the hole and then cover it with a patch.
It is a provisional repair, that is, its role is to temporarily close the hole. This repair is to be applied during an emergency and afterwards it must be removed and a permanent and appropriate repair must be done at a specialized workshop.
O primeiro apresenta uma estrutura maior, o que permite uma capacidade de carga superior. Embora o segundo seja totalmente compatível e mais comumente aplicado no mercado de reposição.
A pressão máxima recomendada em PSI para o pneu rodar com segurança está indicada na lateral do próprio pneu, conforme foto em anexo. Porém, é importante reforçar que a pressão ideal do pneu varia de acordo com o modelo da motocicleta já que um mesmo pneu pode equipar motocicletas com pesos e características distintas, consequentemente variando a pressão indicada. Essa informação pode ser consultada no manual de fabricação da motocicleta, podendo variar conforme as condições de uso.
O prazo de validade recomendado para os pneus é de 5 anos após sua fabricação. A data de fabricação do pneu está marcada em sua lateral, tecnicamente conhecida como flanco, normalmente após a inicial DOT
Todo pneu de moto conta com o TWI (Tread Wear Indicator): um filete de borracha disposto transversalmente aos sulcos em alguns pontos da banda de rodagem. O TWI indica que a borracha acabou e o pneu deve ser trocado por um novo.
É uma camada de composto de borracha sintética que reveste o pneu internamente fazendo o papel da câmara de ar (de estancar o ar sob pressão) no interior do pneu.
Vipal Rubber is a leader in the tyre retreading product segment. Thus, Vipal Machinery combines all the knowledge and experience of the retreader technicians to incorporate customer´s needs into developing their equipment.
