Tyre Delamination Explained
Delamination is an unfortunate process where a tyre separates into its various component parts. There are many causes of delamination which we will touch upon here but the key ones are overloading and underinflation. Modern radial and bias ply tyres rarely fail or cause crashes. However, when failure of a tyre has occurred the most common cause is tyre belt separation, which is another name for tyre delamination.
What Causes Tyre Delamination?
A variety of root causes are attributable to the tyre delamination process. The more common causes are:
- Improper inflation
- Excessive tyre wear
- High speed
- High temperature
- Bad driving habits
- Improper storage
Inflating the tyre, either too much or too little, will cause stress points on the tyre that were never designed to be there. Eventually this causes a slow rupture within the tyre that means the various layers become unbonded. Undetected punctures will have the same effect.
From there, high temperatures are caused when travelling at high speeds, especially for any length of time. Though it is worth mentioning that extreme environmental temperatures will also affect the tyre delamination process.
Improper storage covers every aspect of improper care, including sustained UV damage (often invisible and found on display tyres that may be in garage forecourt windows) and chemical contamination, such as oils, degreasers, steerings fluids and other automotive fluids.
Early Warning Signs of Tyre Delamination
Seperation of the belts may begin as a crack starting between the belt layers, often this is found near the shoulder of the tyre where the tyre wall and tread meet. Once the crack is found, replacement is imperative. This is because the crack is likely to have spread around the circumference of the tyre between the integral layers.
Eventually, the separation reaches a point where the outer tread layers are no longer secure on the inner belt layers; this is when detachment occurs. The most common form of this can be seen by the many discarded tread layers found on British motorways. These are commonly from HGVs and lorries whose tyres have been unable to withstand the load requirements and high temperatures of motorway driving and have failed whilst in motion.
On passenger vehicles, this is far more dangerous a hazard, as HGV-sized vehicles often have many other wheels to act as a backup to the failed tyre.
