Remolded vs. Retreaded Tires

Today, we will take a look at the differences between remolded and retreaded tires. While both of these techniques manage to give a second life cycle to used, worn out tire carcasses, the versatility in the technologies used result in completely different outcomes.

What Are Remolded Tires?

Remolded tires are the closest to new tires among retreaded models. This technique places new rubber along the entire tire, from one bead to the other, which prevents tread separation. Versatile molds are used to shape the new tread pattern of the tires depending on the specific tread desired. Each tread pattern needs a different mold, which makes the process a bit more expensive.

As remolded tires prevent tread separation, they are safer to be used. They guarantee a secure performing capability and a secure driving experience.

What Are Retreaded Tires?

A retreaded tire is any tire that receives a new life cycle by adding a new layer of rubber on the tread area. In this blog post, we are specifically talking about Pre Cure Retreading. This is a complicated process where a high quality tire carcass is taken and given a new tread area.

The process starts by adding a thin layer of cushion gum along the tread area. This will adhere the vulcanized pre-cured tread to the tire. After the cushion gum is added, the retreader adds the vulcanized pre-cured tread pattern onto the tread area. These are held together by staples until they are put into the curing chamber. Multiple tires can be cured at once, which speeds up the process a bit. In the curing chamber, a mix of pressure and temperature is used for a specific amount of time to bond the tread to the cushion layer.

In this manner, the worn out tire receives only a new tread area with a premade tread pattern, which is practically glued to the tire in the curing process. This technique is usually only used with commercial grade and industrial tires, that have more durable casings.

Remold vs. Pre Cure Retread

The main difference between the processes is in the amount of new rubber the worn-out tire receives. Remolded tires are covered with the new rubber from bead to bead, while pre cure retreads only get a new tread area. When it comes to remolded tires, this process prevents tread separation, which is a big issue with retreaded models. Pre cure retreads, however, face the threat of tread separation and it is a recurring issue with such models.

In this manner, it is safe to say that remolded tires are more secure to use in everyday driving. The maintained tread area, optimal performance and excellent durability ensure their safer performing capability in various conditions, making them perfect even for passenger vehicles and SUVs. As remolded tires use the casing of a worn-out tire as their base, they recycle said tire and reduce its carbon footprint. As a result, remolded tires are more environmentally conscious.

At the moment, Priority Tire offers excellent prices on Insa Turbo tires models. This Spanish tire manufacturing brand utilizes the remolding process to give old casings a new life cycle, reducing their carbon footprint.
