DISCOVERER® S/T MAXX™
- Tough terrain Hybrid 4-5 Rib DesignProvides low tread pattern noise and even wear.
- Dual-draft and non-parallel groove wallsHelps to reduce stone retention and resist cutting and chipping.
- Stone ejector ribsAids the discharge of debris and helps to resist stone retention.
There are 14 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

5 classes from E (least efficient) to A (most efficient)
Effect may vary among vehicles and driving conditions, but the difference between a E and an A class for a complete set of tyres could reduce fuel consumption by up to 7.5 %* and even more in case of trucks. Fuel savings and road safety depend heavily on the behavior of drivers and eco‐driving can significantly reduce fuel consumption.
5 classes from E (longest braking distances) to A (shortest braking distances)
Effect may vary among vehicles and driving conditions, but in the case of full braking, the difference between a E and an A class for a set of four identical tyres could be up to 30% shorter braking distance (e.g. for a typical passenger car driving at 80 km/h speed this could be up to 18m shorter braking distance)*. Stopping distances must always be respected.”
In addition to the noise value in Decibel dB(A) a letter (from A to C) displays whether the tyre external rolling noise performance is above the United Nation Reg 117 mandatory limit value
(Class C = noisier tyre), the tyre noise is higher than the UN limit
(Class B = average tyre) or more than 3 dB below the limit value
(Class A = low noise tyre).
NB: The tyre external rolling noise is not entirely correlated to vehicle interior noise.
