You might be familiar with this sliding scale from energy labels on fridges and freezers etc. Fuel efficiency is graded from A (most efficient) to G (least efficient). The difference between best and worst can be as much as 7.5% for cars.
This chart shows wet grip performance measured under strictly controlled conditions and rated from A (best) to G (worst). Essentially this measures how well the tyre brakes on wet roads. The difference between each grade will be one or two car lengths when braking at 50mph. Overall the difference between best and worst (A to G) will be around 30%.
This diagram shows you a tyres’s external noise level in decibels (dB). A single black ‘sound wave’ shows that the noise level is at least 3dB better than the future European mandatory limit, two ‘sound waves’ show that the tyre meets the future European mandatory limit and three ‘sound waves’ show the tyre only meets the current European noise limit. A decibel represents a big difference in noise levels.
All retailers must display EU ratings for each tyre and you can access the ratings for all Landsail tyres on our range page www.landsailtyres.co.uk/tyrerange.
