Kit Loong Tyre Gears Up for Sigma
Atyre comprises of a casing and a tread. However, a casing is not only the foundation of a tyre, but also the foundation of successful tyre re- treading.
The casing is designed for a specific load capacity and performance level, as well as to endure the stress exerted upon it. High quality brands’ tyre casings for com- mercial vehicles, with proper maintenance, will retain their properties well and can be retreaded several times. When we turn a casing into a retreaded tyre, together with our maintenance knowhow, we extend the tyre’s life and lower its life cycle cost.
Growing radialisation in the truck and bus segment has widened the gap in terms of technological differences between tyre brands. Unlike in the old days, with bias tyres, where each of the manufacturers basically competed on load carrying ca- pacity as the mileage difference was not as high as it is today, radial casings de- mand much higher technology. In today’s tyre market, there are hundreds of differ- ent brands offered locally, whilst in the global tyre market, there are even more. Thus, the technology gap is even greater. One manufacturer may produce more than ten brands. Some manufacturers may be using the same casings, but for those more professional and technologi- cally advanced, manufacturers are mak- ing casings with specific applications and performance objectives in mind.
As the tyre goes through its first life, re- gardless of its performance, the casing will almost inevitably be injured, to various degrees, over this period of time. There are different types and level of casing in- juries that can be caused by lack of main- tenance or road hazards. Some of the in- juries are obvious, and can be easily seen on the casing, such as nails that can injure the casing structure. Moisture from water will make the steel rust, as today almost 100 per cent of the casings are of steel construction and hence are called radial steel tyres. If the injuries have been well

吉隆轮胎西格玛多元品牌解决方案
蓄势待发
一条轮胎是由胎体和胎面胶组成的。然而，胎体却不仅仅只是一条轮胎 的基础，也是轮胎翻新成功的基础。
胎体是针对特定的载重能力和性能水平，还有承受施加在它身上的压力而设计 的。正确维修的高品质商用车轮胎品牌的胎体，不但能保持它们的特性，而且还 可以被翻新好几次。当我们以我们的维修知识，将一个胎体变成一条翻胎，我们 就延伸了轮胎的寿命，降低了它的生命周期成本。
卡客车轮胎领域中不断增长的子午化，扩大了各个轮胎品牌之间的技术差距。有 别于过去的斜交层轮胎，制造商们基本上都是在载重能力方面相互竞争，因为里 数的差距并没有像今天那么高。子午胎的胎体要求更高的技术。今天的本地轮 胎市场上，充塞着数百种品牌的轮胎，而在全球轮胎市场上的轮胎品牌数量则更 多。因此，技术的差距也就更大!一个制造商也许生产超过10个品牌。一些制造
