Tyre overheating – do you need to replace the tyre?
Tyre overheating is an undesirable phenomenon and a serious problem that can lead to permanent deformation of the tyre’s structure, thereby rendering it unsuitable for further use. In extreme cases, tyre overheating can result in the tyre’s structure delaminating, the formation of unwanted bulges, or even the tyre bursting whilst driving. The more overheated and worn a tyre is, the more serious the consequences for its users, including the need to replace it with a new one.
An overheated tyre – what is it and what are the signs?
Tyre overheating refers to a situation in which the tyre temperature rises to a dangerous level. For road tyres, the upper limit of permissible
Temperatures range from 80 to 100 degrees Celsius. Under such conditions, the tyre loses its elasticity, the internal layers (steel and textile cords) may delaminate, and the adhesives bonding the tread layers begin to melt.
The most common symptoms of tyre overheating experienced by drivers are:
- a distinct smell of burning coming from the tyres,
- changing the tyre colour to a slightly darker shade,
- a shiny surface.
Drivers should also be on the lookout for any blisters or bulges, particularly on the sidewall or tread. In the most extreme cases, the tyre may become flattened, taking on an egg-shaped appearance or suffering other deformities. Furthermore, whilst driving, the wheel may wobble and the driver may experience instability in the vehicle’s trajectory.
An overheated tyre – will it need replacing?
Depending on the extent of wear and tear, it may be necessary to buy a new tyre. This is the case when the tyre shows clear signs of swelling, bulges or other deformities covering the sidewalls. These are usually impossible to repair, and the only solution is simply to tyre replacement in Warsaw. Furthermore, if a tyre repairer detects delamination or the adhesive melting, the tyre may need to be replaced.
In some situations, however, it is acceptable to continue using the tyre. This applies in particular to tyres that have become slightly overheated as a result of driving in hot weather, with only a slight increase in pressure. Similarly, if the tyre shows no visible deformation and the driver does not feel any jolts whilst driving, it is acceptable to continue using it. Furthermore, if, following a thorough inspection, the tyre repairer finds no significant structural damage, they may simply recommend that the tyre be used further.
