Tires are often replaced sooner than oil changes, same thing on w212 amg. Welcome to the club.

... normal and should be expected per se for the E63S.
alignment will not fix the issue. Just to expect buying new tires every couple of years. Hate to say that.

Crappy Tires
My thread is here:
Two front tires crapped the bed...at the same time. - MBWorld.org Forums
IMO this has nothing to do with camber, every photo has a flat wear pattern across the tire with the inner shoulder giving up. The issue of aligning the car after installation of camber adjustment leaves me feeling like the car would be completely messed up (IE, are you aligning for camber in a lowered suspension setting or normal height, if you align for camber/toe in lowered height what are the characteristics of the car at normal ride height - yikes).
Plenty of suggestions that its toe-out related, but that's not what my alignment said after new tires.
I've had the same experience with Micheline Pilot Sport's on the rear of a Jaguar XFR recently. When I researched following that disappointment I found that several tire manufacturers were advertising more robust shoulder construction in their new designs. To me that clearly acknowledges the issues Michelin and Pirelli appear to be having. My long time tire dealer also conceded that many manufacturers are cutting the compound quality resulting in reduced durability - if Michelin and Pirelli are doing it - we're doomed!
I will say that my tires broke down reasonably suddenly following some very fast hard cornering in the weeks leading up to the failure. I had been running them at 36 psi because they were hell at recommended 44 psi and less so at reduced pressure. I've little doubt that contributed. As for run-flat being a contributor, I don't know, my failure on my Jaguar was not on run-flats.
My gut tells me that running in Sport+ with the lowered ride height puts some toe out into the front end and high speed/hard cornering will produce this outcome. Plenty of drivers do just fine on tire life running in comfort unless its just one of those days that demand the performance. My understanding is that the cars also lower anyway at high speeds regardless of which ride height you've selected.
Only good news is TireRack is still blowing out fronts for $140.

PLAIN AND SIMPLE - EVEN AMG PERFORMANCE MODELS !
OEM / FACTORY THERE IS NO LONGER FRONT CAMBER OR CASTER AND NO REAR CAMBER - To adjust tire contact angles - spread load more evenly. Excess edge loads can also lead to ruptured side walls and rim damage.
IT IS ALL TO DO WITH COST SAVINGS AND EVER INCREASING SPEED OF NEW CAR ASSEMBLY LINES. Stopping to adjust / set Camber is no longer an option. Camber is now preset to suit showroom height. NO LONGER CATERING FOR VARIOUS ROAD OR LOAD CONDITIONS (NEW CAR INDUSTRY’S BEST KEPT SECRET).
The often quoted reassuring FULL ‘4’ WHEEL ALIGNMENT IS NOW ONLY TOE “DIRECTIONAL” ADJUSTMENT.
ONUS IS NOW BACK ON OWNERS TO FUND COSTLY PREMATURE TIRE REPLACEMENT !
AT K-MAC WE SAW THE NEED THEREFORE TO REINSTATE ADJUSTMENT. PLUS THE NEED TO BE “BOLT-ON” KITS - requiring no special tools or need for control arm removal to install. Along with precise adjustment. Accurately (under load) direct on alignment rack.
CATERING FOR DAY TO DAY COMMUTING - encountering high cambered roads with excess passenger side edge wear. Or noticeable edge wear - both sides through extra passenger loads or lowering. Plus allowing ongoing adjustment capability for curb knock damage.
FIXING IT RIGHT THE 1ST. TIME - Ending the frustration of going from one dealer or alignment shop to the next or deciding it must be a tire brand issue.
