I am now on my 4th pair of rears and 2nd pair of fronts on my 2013 C220 AMG+ and I have no intention of buying anything else. Not noticed a significant difference between these and the Continental tyres fitted when the car was new. I drive 40,000 miles per year, mainly on motorways and I am getting around 20,000 miles out of a rear set and 40,000 miles out of a front set. I tried them as buying 6 tyres a year is expensive and I figured at £225 for the set fitted these were worth a shot. Very pleased and have now done nearly 100,000 miles on Infinity Ecomax tyres without any problems. Even on wet greasy roundabouts the car is predicatable and only when the tyres get fairly worn do I see any stability/traction control intervention on wet roads - and then it is only pulling away hard from T junctions etc
