Rear tyres on a C63AMG can be reduced to nothing in very short order. That said, if you keep an eye on fuel consumption and don't drive like its stolen every day, you can get plenty from the rears. I like to 'push-on' wherever and whenever possible - Early Sunday AM blasts, etc. Yet managed to get 31,000miles from the rears, which I am told is pretty good. That is of course if you do not pick up nails/screws - which I have done twice on the fronts.... £1000 in front axle tyres in 9 months thanks to UK roads PLC and the lack of road sweeping/cleaning.. A German friend of mine states there would be a revolt in Germany if this were to happen.
Mich Pilot Super Sport M01 - standard factory fit on the 2016 C63 - simply amazing tyres in my view, good wear, great grip (wet and dry/summer & winter) confidence inspiring with good, even, wear characteristics. Bit on the noisy side though, but what can one expect from a performance estate car? Pricey ? yes. Too pricey when you consider that cannot be puncture repaired. Availability... currently having to wait two weeks for a set, not readily available it seems.
