Just had the enormous pleasure of having new tyres fitted.
By law, they now have efficiency ratings to help you with your choice, just like fridges and washing machines.
Previously they were round and black and we bought on price, thinking the more we pay the better the tyre (hopefully)
Now they are rated for Noise, Fuel efficiency and Wet grip.
Ratings are A,B,C and so on with A being the best. So now you can make an informed selection.
Remember 1.6mm minimum across the centre 3/4.
Don't forget tyre pressures, They are hugely important for road holding and safety.
Good innit ?
