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.
