There are 31 tire sizes available
The tire size is made up of: Tread Width / Aspect Ratio / Rim Diameter. For example 245/50R18
The tire width is a millimetre measurement for the width of the tire. For example 245 mm when reading a tire size of 245/50R18
The aspect ratio is the percentage of the height of the sidewall compared to the tread width. For example 50% when reading a tire size of 245/50R18
The maximum load a tire can carry is defined as a ‘Load Index’. Please refer to https://www.coopertire.co.uk/tire-safety-tips/correct-loading/
The Speed Symbol is shown as a letter and indicates the maximum speed. Please refer to https://www.coopertire.co.uk/tire-safety-tips/correct-loading

Rolling Resistance is the main key factor in measuring the energy efficiency of a tire and has direct influence on the fuel consumption of a vehicle. A set of tires 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 drive by noise is quoted as an absolute value in decibel and as a 3 classes sound wave symbol.
