After 3 sets of crappy summer tyres and not being able to use my car in bad weather once they had worn down to 3mm (kwik fit won’t replace until 2mm) I bought a full set of 4 All Season tyres for about 20% less than kwik fit charge for summer ones, I had them through one winter and swapped front to back the next autumn so they did a 2nd winter, good value but Motability wouldn’t pay for all season even though they were cheaper than summer tyres, blind stubborn stupidity on their part!
