Which tyres for what type of vehicle?
First selection criteria: The vehicle type. Whether you drive a city car, a saloon, a van or a 4x4, always follow the manufacturer’s recommendations.

It is important to know that the tyres originally fitted to your vehicle, or “original equipment” tyres [See box below], are approved by the manufacturer in agreement with tyre manufacturers. Particular account is taken of:
- Wheel housing,
- Rim sizes,
- Vehicle’s speed performance,
- Vehicle weight.
How good are original equipment tyres?
“Original equipment” tyres are quite simply the original tyres; those that the car manufacturer chose to equip its vehicle. Are they the best reference? Not necessarily.
Some tyres are designed specifically for a manufacturer. This special manufacturer’s approval presents the specific characteristics of your tyres. [See our article on tyre markings]. These markings include the tyre construction details, load capacity and speed rating. These characteristics are marked on the tyre sidewall.
However, theoretical dimensional equivalency tables do exist. The European Tyre and Rim Technical Organisation (ETRTO) brings together the well known tyre manufacturers and establishes certain standards, starting with a base dimension, in order to use compatible variants with the technical characteristics of the vehicle.
The criteria used by the manufacturer may be different from yours. The following hierarchy is most often adopted:
1. Road handling
2. Rolling noise
3. Dry braking
4. Wet braking
The reason is simple: The driver usually assigns the first three criteria … to the vehicle!
When you change your tyres, there is no reason for you to choose the same brand and model initially selected by the manufacturer. You just need to meet the specifications the manufacturer has outlined for your car.
