Perth Tyres - tyre labelling and understanding labels
All new tyres sold must be labelled in a certain way. The label must provide information regarding noise emissions, fuel efficency and wet weather performance. This enables the consumer to make comparisions between different tyres and ensure that thier specific requirements are met. The example label shown here demonstrates the peramaters that are covered.
Rolling resistance is the main key factor in measuring the energy efficiency of a tyre and has direct influence on the fuel consumption of a vehicle. A set of tyres of the green class "A" compared to a "G" class can reduce fuel consumption by 7,5% of a passenger car; even more for trucks.
Basis for wet grip is the absolute stopping distance when driving 80km per hour. Between each class, there are 3-6 metres difference in braking distance.
The driving by noise is quoted as an absolute value in decibel and as a 3 classes sound wave symbol. A continuous sound level above 80 decibel can cause health problems.
