I picked up four 225 45 R17 91W Michelin Primacy HP from 2011 - Seller had bought a new KIA Ceed and had the tyres removed a few monthe later so he could have snowtyres on the original rims - 2 of them are like new and approximately 1 mm worn of on the other 2 tyres. Paid 220 pounds.
Tomorrow I'm going to pick up 2 almost new 245 40 R17 91W Michelin Primacy HP from 2011 tyres from a Mercedes SLK for 186 pounds...
Having them fitted costs 44 pounds....
Total cost 450 pounds - for 6 tyres seems like a fair deal to me

Been travelling in France for many years - did'nt know they had a museum in Clermont Ferrand - a new destination added to the "I have to see this" list.
