An average of two accidents happen daily due to tyre combustion or tyre debris on the road. PLUS Malaysia Bhd recorded 613 road accidents last year on the expressway due to these factors.
Heavy vehicles tend to go for retreaded tyres for the obvious reason.
“A retreaded tyre is usually 50% cheaper than a new tyre,” said Pan Malaysia Bus Operators Association president Datuk Mohamad Ashfar Ali.
Stressing that his members would not buy uncertified retreaded tyres, he said the low quality of some of these illegally tyres could cause them to explode while the vehicle was moving.
These tyres might burst due to overloading, casing, or that the rubber and the glue used on the tyres were below par.
“The tyre is the only contact point between the road and the vehicle. So, it must be able to withstand the heat, the high speed the vehicle is travelling in and the load of the vehicle,” he said.
As such, he said, express buses on long journeys would be fitted with new tyres while normal buses that travel short distances would be installed with retreaded tyres at the back wheel.
Such tyres must come only from certified manufacturers, he said, adding that a tyre should ideally be retreaded only once.
Mohamad Ashfar urged the authorities to crack down harder on illegally retreaded tyre manufacturers.
Pan Malaysia Lorry Owners Association president Jong Foh Jit acknowledged that it was common for lorries to use retreaded tyres as they were cheaper.
“But they must ensure the tyres are certified by Sirim,” he said.

“Some people are tempted to go for cheaper, illegally retreaded tyres due to the economic slowdown, but they may endanger themselves and other road users,” he added.
Jong said some lorry operators would retread a tyre two to three times.
Tyre Retreading Manufacturers Association of Malaysia said it was high time the authorities clamped down on unscrupulous tyre retreaders.
The move would force retreaders to get the Sirim certification and start complying with government standards, association president Chin Hong Meng said.
“We have been encouraging them to get Sirim’s MS224 certification since 2007. That’s 10 years ago! We’ve already given them ample time. It is high time that enforcement was carried out,” he said.
Transport Minister Datuk Seri Liow Tiong Lai slammed illegal manufacturers, saying that many fatal accidents were caused by retreaded tyres that did not meet standards.
