average miles
I had a set of 225/40R18 CONTI SPORT 5 SSR Runflats on the front of my Mercedes from new - great grip in the wet and dry but terrible mileage!
I work in the tire industry for a living and although Conti have a great OE share within Europe (30% apparently) their replacement share is one of the lowest out of the Premium brands.
