New tyres labelling legislation comes into force later this year to help motorists choose the right product for their needs and potentially reduce the cost of running their vehicle.
From 1st November all tyres sold in the UK will be required to display information about wet grip, rolling resistance, or fuel efficiency, and noise as part of a wider EU legislation.
The rolling resistance ratings will be displayed as coloured bands from A-G, A being the best and G being the worst, with the difference between each grade equalling a change in fuel consumption of as much as 4.5 per cent.
Wet grip will be measured in the same way, with the difference between each grade equalling a stopping distance of between 3 and 6 metres when travelling at 50mph.
External noise will be measured in decibels and split into three categories represented by black sound waves – with one sound-wave representing the quietest tyres.
The new labelling rules will apply to car and sports utility vehicle (SUV) tyres, van tyres and truck tyres but not to re-treaded tyres, off-road tyres, spare tyres or vintage car tyres.
