There are two ways to retread tyres

 

PETALING JAYA: The process of retreading a tyre, through hot curing or precuring, can take two to three days.

The hot curing method is akin to making a new tyre, where several compounds are applied onto a tyre casing before it is placed in a curing mould.

Precuring, on the other hand, is done via gluing a layer of precured tread onto the tyre casing.

The second method, according to Tyre Retreading Manufacturers Association of Malaysia president Chin Hong Meng, is more complex but it allows the tyres to last longer.

“Ideally, a retreaded tyre using the precuring method should be even better than a new tyre. However, the process is more complex and more expensive,” he said.

Chin said that retreaded tyres cost around 70% of the price of a new tyre.

“Of course, if they provide us with their tyre casings, the price will only be 30% to 50% that of a new tyre,” he said.

In a reply to The Star, Sirim said before a tyre is retreaded, its casing must be of good quality and pass inspection.

Before a retreaded tyre is sold, it must pass quality control tests as well as a performance test.

Retreaded tyres which follow Sirim’s standards are given a warranty that they can perform well under normal operating conditions.

“In order to provide safe operational performance levels, retreaded tyres used on commercial vehicles shall undergo the endurance performance test,” Sirim said.
