Tyre calculator
The wide and varied range of car tyres is constantly being updated with new tyre models that offer improved performance and grip on dry, wet, or damp roads, as well as new features aimed at enhancing driving comfort and safety. To select the best tyres for your car from the extensive range available, the technical characteristics of the tyres must be aligned not only with your budget for the purchase but also with the specific make of your car and your individual driving habits. A tyre calculator can significantly simplify the process of choosing safe tyres.
Choose the tyre size you need
How do I choose new tyres for my car?
Tyres are the only point of contact between the car and the road, so their quality and ability to grip the road surface well is crucial to ensure good handling on the road and optimum car performance according to the car manufacturer’s calculations.
This is why car manufacturers work closely with tyre manufacturers to determine the optimum tyre parameters for each make of car.
This information can be found in:
-
- In the Driver’s Handbook;
- On the driver’s side door label;
- In consultation with experienced tyre service staff;
- Tyre calculator.
What aspects should I consider when choosing tyres?
There are no accidental parts in the car’s design.
Inadequate tyres not only reduce the handling and performance of the car, they also increase structural damage and compromise road safety.
New tyres need to meet both the car manufacturer’s recommendations and individual preferences, as well as road conditions and driving habits, so there are a number of aspects to consider when planning a tyre replacement:
-
- Tyre diameter, width and height;
- Technical parameters such as tyre load capacity and speed index;
- Seasonality – winter, summer or all-season tyres;
- Tyre age;
- Tyre compound quality;
- Budget – premium, mid-range or budget tyres;
- Tyre tread pattern;
- Other features such as noise performance, fuel economy, run-flat technology, etc;
How can the wrong tyre choice affect the handling of your car?
The wrong tyre diameter, width and height for the make of the car has a significant impact on the car’s handling, because increasing or decreasing the tyre size also changes the car’s acceleration potential, rolling resistance, inertia, chassis height and centre of gravity proportionally.
These aspects increase the car’s roll and reduce the car’s cornering precision.
The greater the deviation from optimum tyre sizes, the more difficult and tiring driving becomes.
How can a tyre calculator help me choose tyres?
While information on the most suitable tyre sizes for a particular make of car can be found in the driver’s handbook or on the markings on the existing tyre and driver’s side door, the tyre calculator offers a quicker and more convenient way to find the right tyres for your car.
The tyre calculator provides up-to-date information on the most suitable tyres for your car and links the search results to the tyre service depot so you can order the tyre kit of your choice instantly.
What if I want to change tyre size?
If you are planning to change tyre sizes, it is worth remembering that most often there are several tyre sizes for a car make – optimum, reduced or increased.
The overall diameter of the wheel should only vary by about 2% from the manufacturer’s specifications to avoid any negative effects on the performance of the car and the design of the running gear. The tyre calculator will provide safe alternatives to changing tyre sizes according to the information entered.
