Tyre Grades

The labels seen on tyres are from Europe.

These EU tyre label provides important safety and environmental information about each tyre. It helps consumer to compare tyres according to their desires and driving habit.

The three icons above are fuel efficiency (left), wet grip (right) and noise (bottom)

Wet Grip

Wet grip is designed for braking performance of tires on wet road surfaces and is related to the safety performance of vehicles.

Such tyre have lesser rolling resistance and high fuel efficiency, but can have safety issues.

Low rolling resistance have low adherence to roads when the roads are wet.

 

Wet Grip tyres are categorised the same way as Fuel Efficiency, ranking from A to G. Class A being the most efficient at breaking, while class G being the worst.

 

Effect may vary among vehicles and driving conditions. The difference between G and A class for a set of four identical tires could be up to 30% shorter braking distance (e.g. a typical passenger car driving at 80 km/h speed this could be up to 18m shorter braking distance). 

Noise

Some percentage of the pass-by noise a car makes, comes from the tyre. These external sounds are measured in decibels (dB) and it is illustrated on the labels with a 3-wave pictogram. The more waves, the louder it is.

 

1 wave bar is the best you can get. Tyres with this rating are the quietest tyres and can be considered low noise tyres.

2 wave bar is consider moderate and complies with the European legislation.

 

3 wave bar suggest the sound level is noisy though it complies with European laws.

 

After all, low noise and comfort often go hand in hand and are big considerations when buying tyres, as well as performance, especially for customers who do a lot of driving.

Fuel Efficiency

The fuel efficiency tyre is measured by rolling resistance.

Resistance occurs when a round object rolls on a flat surface in a steady velocity straight line motion. It causes deformation of the object or/and surface. Additional factors which contributes to rolling resistance includes wheel radius, forward speed, surface adhesion and relative micro-sliding between the surfaces of contact.

 

Tyres are rated from A to G. Class A tyre consumes the least fuel to move the vehicle as it has the lowest rolling resistance. Therefore, lesser energy is used while covering long distance.
