What is hot retreading?

HOT retreading: Hot retreading involves the vulcanisation of a tyre in a mould at a temperature of around 150 °C. The shape and tread of the tyre are created in the heating press. Arguments in favour of hot retreading: Suitable for all tyre applications, including car and aircraft tyres.

What is the process of tyre retreading?

Tyre Retreading Process

  1. Collection of Casings. Worn tyres are collected to select suitable casings for tyre retread.
  2. Initial Inspection.
  3. Buffing After inspection.
  4. Section Repairs & Skiving.
  5. Cementing and Filling.
  6. Building – Tread Rubber.
  7. Curing by Chamber.
  8. Final Inspection & Painting.

How are tyres remoulded?

Remoulding is the process by which the carcass of a used tyre is recycled. The remaining tyre tread on the used tyre is stripped away and new rubber is moulded to the carcass in order to replace the sidewalls and tread with a new, roadworthy finish.

Can all tyres be retreaded?

Used tyres with good sidewalls can be rebuilt and put back to work again, and again. A well-constructed truck or bus tyre can be retreaded two, three, or more times, depending on quality and condition. At the end, only one worn tyre casing is disposed of instead of many, yet another benefit of retreading tyres.

What does remold tires mean?

Remould tyres, also known simply as retread tyres, regrooved tyres, retreads or remoulds, are used tyres which get remanufactured in such a way that their worn tread is replaced with a new tread without changing their structure.

How good are retread tires?

Retreading is the process in which the casings of worn tires are reused and receive new tread. In spite of the bad reputation that tire retreads have, the federal government has found they are not more dangerous than regular tires.

Is tyre retreading safe?

Retreading tyres is considered quite safe and is used in a variety of vehicles. Retreaded tyres are subject to a similar safety process as new tyres made at the factory. The labour and cost of retreading are much less expensive and more environmentally friendly than creating a new set of tyres.

How good are remolded tires?

Remolded tires have a lot of benefits that new tires cannot beat: They’re up to 40% cheaper than new tires. They’re excellent for off-roading (especially if you look at our Kedge Grip tires) They’re much better for the environment – Remolded tires only require a fraction of the oil that new tires do.

Are remold tires safe?

Retreaded tires have come a long way. They are not as dangerous to use as they used to be when they first popped up on the tire market. These technologies give a second life to worn out tires and different technologies result in different tire durability.

Is tire retreading profitable?

Retreads: A Reliable, Profitable and Sustainable Business Solution for Fleets. Manufacturing a retread saves 15 gallons of oil over manufacturing a new tire. Approximately 15 million commercial truck tires are retreaded each year, which can help save up to 225 million gallons of oil annually.

What is the difference between hot retreading and precured tyres?

Heat build-up in the tyre, rolling resistance and other tyre properties are often easier to assess than with hot retreading. With comparable tread geometries, the running performance of a precured retread is often better than a hot retread and the same as an equivalent new tyre.

What is hot retreading and how does it work?

Hot retreading involves the vulcanisation of a tyre in a mould at a temperature of around 150 °C. The tread and the sidewall veneer of the tyre are made up of non-vulcanised rubber compounds. The shape and tread of the tyre are created in the heating press.

Why do aircraft tyres need to be retread?

Retreading plays a particularly important role in aircraft tyres, which are subjected to extreme stresses. Aircraft tyres have to withstand huge strain at speeds of over 250 km/h, and undergo retreading after around 150 take-off and landing manoeuvres.

What is tytyre retreading and how does it work?

Tyre Retreading is a technology, where the old tyres are made serviceable by removing worn out and damaged treads (rubber belts) and replacing it with new treads. Similar to the new tyres, the treated tyres can be very well used on all vehicles, irrespective of light or heavy vehicles.
