Why Retread?

An Excellent Value; Retreaded tyres are great value for money. 

Retreaded tyres can and do perform as well as tyres that have never been retreaded and they do it at a substantial savings over the high cost of new tyres. Fleet owners, construction companies, transporters and private vehicle owners all purchase retreaded tyres for one reason - to save money. 

It should be remembered that every major truck tyre manufacturer, with no exceptions, manufactures its tyres for multiple lives, meaning they are designed to be retreaded. So when an owner operator or a fleet manager doesn't retread his tyres, he is simply throwing money away. 

The useful casing life is maintained and managed closely by the tyre owners as tyres are the number one maintenance cost of operating commercial vehicles and on road down time is very expensive. 

A retreaded tyre cost less to produce than a new tyre and sells for less - usually between 40 to 60 percent of the comparable new tyre price. Retreading is an effective way to lower tyre cost. 

Tyre Retreading Process

Tyre Retreading Process (General)

1. Collection of Casings

Worn tyres are collected to select suitable casings for tyre retread.

2. Initial Inspection

Each tyre received in a retread plant is subjected to a rigorous visual inspection. Inspectors are assisted by the use of non-destructive sophisticated inspection equipment like the Spectra or general inspection machine.

3. Buffing After inspection

The tyre’s old tread is mechanically removed on high speed buffers. Today’s buffers are extremely accurate and will remove the proper amount of old rubber while turning the tyre to an exact specified diameter and radius. Collaboration with international leaders like MATTEUZZI enables Newera to build computerized world class equipment under license for Asia.

4. Section Repairs & Skiving

With advances in state-of-the-art repair materials and repair methods, many of these tyres can be routinely repaired and in most cases can be retreaded when the original tread is worn off. The repair station is where any surface injury is treated using effective material and tools for grinding and patching.

5. Cementing and Filling

Even in small injuries it is critical that the injury is cleaned and filled. If this is not done, severe rust, separation and steel cable looseness could take tyre out of service. The injury should be inspected, and then cleaned out with a carbide cutter. After cementing the injury, a vulcanizing rubber stem should be applied to “fill” the injury. This would create a permanent repair that maximizes tyre life.

6. Building – Tread Rubber

In the pre-cure system, the tread rubber has already been vulcanized with the new tread pattern design. The buffed tyre needs a thin layer of cushion gum to be wrapped around its crown area. The pre-cured tread rubber is then applied with the building machine. This is called the building process.

7.

a) Enveloping & Rim Mounting or

The built tyres are then mounted with envelops and rims to prepare them for curing.

b) Double Envelope System

For enveloping, tyres are first fitted an outer envelope at the envelope-mounting table before the inner envelope is fitted into them. The enveloped tyres are then vacuumed out for preparation prior to curing. Modern plants have their casings hoisted by monorail systems. 

8. Curing by Chamber

The tyre is then placed in a curing chamber and the pre-cured tread becomes adhered to the tyre through a vulcanizing process.

The monorail & hook system increases productivity by cutting down on chances of casings contamination and allows for faster loading and unloading of tyres. This increases your work place safety and productivity.

9. Final Inspection & Painting

The retreaded tyre is subjected to a final inspection. This inspection insures that only tyres that meet industry quality standards are allowed to leave the retread plant. All retreaded tyres are encouraged to be returned with the sidewalls painted using a light coat of black tyre paint.

Retreads Are Green

The synthetic rubber components in the new tyre contain petroleum oil. Therefore, retreading is highly environmentally friendly and should be considered as the best practical environmental option for tyre recycling. 

Unlike other forms of tyre recycling or disposal, retreading does not simply defer the eventual disposal of the tyre, but actively contributes towards reducing the amount of tyres being used and hence saving valuable natural resources. 

Every retread produced means one less new tyre, thereby minimising the number of new tyres produced annually, extending the life of the original product and saving substantially on resources such as oil ( a passenger retread requires 20 litres less oil than a new tyre. For a truck tyre this figure is 68 litres). The result is less tyres to be disposed of annually. At the end of their first, second or even third life retreaded tyres can be used as raw material for other forms of 'deferred disposal'. This is consistent with the Government's sustainable development policy. 

Be a friend to your tyres. Whether they are new or retreaded, maintain the correct inflation pressure. In this way, you will make sure they are well maintained and will be retreadable when the thread is worn off, and you will save fuel in the bargain. 

Are Retreads Safe?

Yes, they are! More than 100,000 aircraft retreads are used annually with an average of 270 takeoffs and landing per tread life. Airlines average six retreads per tyre, with some tyres being retreaded as many as 12 times.

Professional retreaders adhere to stringent industries proven and approved practices at every step of retreading process with sophisticated machinery. Since November 2007 it has been a legal requirement in Malaysia, for retreads to be manufactured according to MS224 (Retreaded pneumatic rubber tyres for passenger cars and commercial vehicles), which stipulates that retreaded tyres are tested to the same load and speed criteria as new tyres.

The introduction of the regulations as a mandatory requirement has made a considerable contribution towards ensuring and proving that the quality, integrity and performance of retreaded tyres are, at the very least, on a par with that of new tyres.

Tiada Pembanterasan Punca Tayar Celup Tak Berkualiti Dipasarkan

Source: Berita Harian: Senarai kilang tayar celup yang menghasilkan produk yang tidak memenuhi pengiktirafan Malaysia Standard (MS) sudah diserahkan kepada Kementerian Perdagangan Dalam Negeri Koperasi dan Kepenggunaan (KPDNKK).

Presiden Persatuan Pengilang Tayar Celup Malaysia (TRMAM), Chin Hon Meng, berkata pihaknya menyerahkan senarai itu tahun lalu tetapi mendakwa kilang terbabit masih beroperasi dan mengeluarkan produk.

Katanya, kilang terbabit masih lagi wujud serta menguasai sebahagian pasaran tayar celup kerana faktor harga yang rendah.

Katanya, pihak TRMAM dan Lembaga Getah Malaysia (LGM) telah lama menyedari kewujudan banyak kilang tanpa pengiktirafan sejak kerajaan mewajibkan MS 224 sejak November 2007.

"Kami hanya boleh menyenaraikan kilang tanpa pengiktirafan apabila KPDNKK meminta sebagai rujukan pada tahun lalu," katanya ketika ditemui di kilang Suntex, di sini.

Sebelum ini BH mendedahkan tayar celup menjadi antara punca utama nahas jalan raya dan pengguna menuntut kerajaan mengharamkan tayar jenis itu.

Berikutan itu, TRMAM mendedahkan sebanyak 30 peratus daripada 1.2 juta tayar celup di pasaran negara ini tidak berkualiti.

Hon Meng berkata kilang tanpa pengiktirafan itu, beroperasi seperti kilang tayar celup yang lain namun mereka melangkau proses penandaan MS 224 yang diiktiraf SIRIM Bhd pada tayar.

"Proses mendapatkan penandaan MS 224 bukan perkara mudah kerana membuat tayar celup perlu melalui sekurang-kurangnya tujuh peringkat penting disebabkan ia berkait rapat dengan soal keselamatan dan nyawa pengguna jalan raya.

"Kami sendiri akui terdapat banyak serpihan tayar celup di atas lebuh raya tetapi apabila diperhatikan, banyak yang tiada penandaan MS 224 khususnya apabila serpihan yang berbentuk sebiji tayar," katanya.

Ketua Seksyen Bahagian Penguat Kuasa KPDNKK, Othman Nawang, ketika dihubungi berkata perkara itu akan diteliti.

100 Retreaded Tyre Manufacturers Fail Sirim Standards

PUTRAJAYA: Almost 100 retreaded tyre manufacturers in Malaysia fail to meet Sirim standards, says Transport Minister Liow Tiong Lai.

100 Retreaded Tyre Manufacturers Fail Sirim Standards

He said retreaded tyres that did not meet Sirim standards were a threat to the safety of motorists.

“We will go after them (illegal retreaded tyre manufacturers),” he told a press conference on the special integrated operation to nab manufacturers of illegal tyres here yesterday.

Liow said a retreaded tyre certified by Sirim cost about RM1,150 while a fake retreaded tyre was much cheaper at about RM400.

He said 82 retreaded tyres manufacturers had received Sirim certification.

Retread, also known as “recap,” or a “remold” is a re-manufacturing process for tires that replace the tread on worn tires.

Liow said a special enforcement team from the Road Transport Department (JPJ) seized and impounded 480 retreaded tyres and 1,374 fake Sirim stickers worth RM247,500 in two operations recently.

The team picked up two factory owners and nine foreign workers in the raids in the Bukit Beruntung Industrial Area in Selangor on Feb 23, and in the Senawang Industrial Area in Negeri Sembilan on Tuesday, he said.

Both cases are being investigated under Section 29(2)(b) of the Trade Description Act 2011 for tampering with the marking of pneumatic tyres which provides a fine of up to RM100,000 or a maximum jail term of three years or both, if convicted.
