Overview of the Industry
Whilst the under-inflation of tyres is the single biggest cause of excessive tyre-wear, the operating cost of truck tyres is the second most expensive item from ay trucking company, after diesel.
Driving a loaded truck on under-inflated or flat tyres causes substantial heat build-up and distortion of the profile, which destroys a tyre completely; not just the tread, but the side-walls and the carcass – the shreds of tyres found along side roads are testimony to this. An under-inflated tyre also increases drag and consequently excessive fuel consumption.
When a ‘flat’ occurs on a side-by-side dual tyre configuration, the good tyre then bears the load of both, causing unwarranted wear. If this condition persists, the two tyres bulge and rub against each other causing tremendous heat build-up in both tyres – the result of course, is the destruction of both; a costly puncture not to mention the down-time of the vehicle.
Globally, it is quite common to see shredded tyre debris on the highways and byways. These large chunks of rubber pose danger to not only the truck itself or other road-users, but to the environment. The repercussions from a single tyre shred could inflict substantial financial damage and impact on company image. The millions of bits of tyre fragments and discarded casings have a detrimental impact on the environment – 75% of all roadside ‘flats’ are preceded by a slow leak.
A single bus accident highlights the need to protect human life. The vast amount of revenue spent to encourage tourism, further accentuates that need to protect traveller visiting our country from abroad, whilst travelling in buses with potentially hazardous and unprotected tyres.
Any tyre manufacturer will confirm that regular checking of tyre pressures is the single most important aspect to obtaining optimum tyre life and lower costs per kilometre. |
