All car tyres are round, black things with sidewalls and treads, and they need to be inflated from time to time. So, they’re all the same, aren’t they? In fact they aren’t all the same and to say they are is just like saying all houses are the same.
This is about the difference between common aspects and specifics. True, every house has a roof, doors and windows but a two-up, two-down terraced property and a mansion, though they’re both houses, are clearly very different. The same goes for tyres, albeit less obviously. Here, we can consider five distinct types of tyre, and these will illustrate the differences.
Standard or all-season tyres are the most commonly fitted type of car tyre. As their name implies, they’re the jack-of-all-trades of the tyre world. They work well in both dry and wet conditions. They aren’t too noisy on most road surfaces and their fairly hard rubber compound gives them a long life. These factors represent compromises, of a kind that work for most requirements – and for most drivers.
Performance tyres, on the other hand, balance certain factors in order to enhance certain characteristics. Car tyres of this kind don’t last as long as standard tyres but their softer compound yields better grip. Similarly, performance tyres don’t appreciate colder conditions, which is why they’re often called ‘summer tyres’. They also don’t readily suffer significant wear. Performance cars – and demanding drivers – deserve performance tyres.
Winter tyres are car tyres for use when snow and ice are liable to be encountered. These tyres have a more marked tread pattern, which is great for giving the best grip and preventing snow and ice from packing in the treads’ grooves. They are also made using compounds that remain flexible even when thermometers are reading low. Some even have integral metal studs to maximise grip. The costs for these specific characteristics are twofold. First, winter tyres create a lot of noise, even on smooth roads. Second, in normal conditions, they wear very quickly and can damage the road surface. The kind of conditions where you’d need winter tyres are obvious, as is the fact that they can’t be used year-round.
All-terrain tyres are the top of the range tyres for unfriendly conditions. Their big, open, chunky treads can grip on loose surfaces such as gravel and sand. Knowing that such surfaces are liable to be in rough country, manufacturers make all terrain tyres with tougher, stiffer sidewalls so they’re less susceptible to damage from potholes and debris. These tyres are sturdy and generally long-lived, at the cost of a considerable noise level on smooth tarmac. There is a still more specialized tyre for adverse conditions. Mud tyres have an extremely large tread block pattern and are suitable for use only in muddy conditions.
Car tyres of this kind are often used on the kind of four-wheel drive vehicles that are actually taken on rough roads; this includes 4×4s that specifically go off-road regularly.
Finally, run-flat tyres are car tyres that are capable of still being used even though they’re no longer inflated because of a puncture. Now appearing on more and more modern cars, they allow you to retain control of the vehicle despite being at zero pressure. However, they can run flat only for a given distance and at reduced speed – your car’s handbook will have the necessary details.
Which type of car tyres you choose to buy is clearly a ‘horses for courses’ decision, largely depending on what you want from the tyres. However, should you be in any doubt, the staff at any good tyre bay will be happy to give you their professional opinion on what type will be best for you.
