Do you know you have different car tyres for different seasons? Should you change your car tyres for every season? Let me explain you about this in detail in this post.
Note: Throughout this post, I will be using the word ‘tyre’. The word ‘tyre‘ and ‘tire‘ means the same. They vary as per British English and American English
Various types of car tyres:
Many car owners have never heard about the various types of car tyres depending on the season. You have three types of car tyres depending on the season. They are:
- Summer tyres
- Winter tyres
- All season tyres
Summer tyres are made up of hard rubber tubes. The summer tyres are usually fitted with expensive alloy metals. These tyres are fitted during summer seasons.
Summer tyres are so hard that they offer better gripping during summer seasons.
Winter tyres are usually made up of a soft rubber compound. They are employed in cooler conditions where the temperature is generally less than 7° C. They are also suitable for rainy conditions and snow conditions.
The winter tyres are usually fitted with steel rims and not expensive alloy metals. Because the expensive allow metals can corrode when comes in contact with moisture (snow).
Winter tyres are so soft when you compare with Summer tyres, because of the presence of Silica in the winter tyres.
All season tyres:
All season tyres usually compromise both summer tyres and winter tyres. Many car manufacturers use all season tyres because it is so simple that you “Set it and Forget it“.
What are the important differences between summer tyres and winter tyres?
When we compare both summer tyres and winter tyres, we find that some important characteristics vary. The important ones are:
Winter tyres have a deeper tread when compared with summer tyres.
Winter tyres are so soft whereas summer tyres are very hard.
Glass transition temperature:
Winter tyres have low glass transition temperature whereas summer tyres have higher glass transition temperature.
What is glass transition temperature and how it impacts summer tyres and winter tyres?
Glass transition temperature is nothing but the temperature at which the polymer changes from glassy state to rubbery state.
Below the glass transition temperature the polymer is going to be hard, brittle and plastic and above the glass transition temperature, the polymer is going to be soft, flexible and elastic.
The winter tyres are made up of materials with low glass transition temperature. So that they easily attain the rubbery state ( soft).
The summer tyres are made up of materials with higher glass transition temperature. So that they remain in the glassy state ( hard)
Which tyre should you prefer in cold conditions?
In colder conditions where the temperature is less than 7° C, winter tyres are preferred. Winter tyres have a deeper thread when compared to summer tyres. The deeper tread allows the snow to pass through. Thus these tyres remain so flexible even at low temperature.
You can also go with All season tyres.
Summer tyres are not preferred during cold conditions because these tyres are so hard. It does not provide the required traction in the snow to stop the car. Also, the summer tyres have smaller tread when compared to winter tyres. Thus, when you hit the brake in the snow with summer tyres, you are going to travel extra distance which is dangerous.
Which tyre should you prefer in summer seasons?
Winter tyres are not preferable for summer seasons because they wear out easily when it gets hot. They also have higher rolling resistance. Thus they are going to consume more fuel. So, it is not a good idea to use winter tyres during the summer season. Also, driving with winter tyres in summer season disturbs your driving comfort.
If you have fitted all season tyres in your car, no worries.
Summer tyres are the best for the summer season. Because the summer tyres become sticky at high temperature. They are so hard and they offer a better traction with the road.
Here is a video from Auto Express, which explains about usage of winter tyres and summer tyres.
