We used Bandag in Georgia.
Supposively, they were safer than brand new tires.
Hot retreading involves the vulcanisation of a tire in a mold at a temperature of around 150 °C/302 °friend . The tread and the sidewall veneer of the tire are made up of non-vulcanised rubber compounds. The shape and tread of the tire are created in the heating press.
There are a couple of different methods in which retreads are produced. There is a hot method using a mold, and a cold method, in which pre-cured rubber is used.
In the hot method, raw rubber is laid to the prepared tire surface, after the old tread has been completely removed. As the hot, raw rubber is put onto this surface, it is covered and cured with a mold. As the rubber vulcanizes, it bonds with the old tire, creating a new tread.
The cold method is somewhat similar, yet a previously constructed tread band is added to the buffed tire and then bonded with the old tire.
