Ever since I got my C63 (C205 C63S Coupe), I've been struggling to get the power on the road as the torque available completely overwhelms the ContiSport 5P's, leaving me with an ever increasing sense of trepidation for every additional centimetre of throttle. Sometimes the car would throw a wobbly (quite literally) and at other times it felt like it was going to throw me into the nearest lamp post.
I think I've found a solution - I knew the ContiSport 6's were better tyres from my experience with them on my previous C63 (C204). On the C63S, they are a total game changer. I can now use 90%-100% throttle, where I was limited to 50% before. The last 10% might get the tyres to spin, but without the car threatening to kill you.
Moral of the story - the C63 deserves better tyres. For me, the slightly wider (see below) ContiSport 6's do the trick (and I suspect the incoming Michelin PSS will perform similarly). My hope this helps some other C63 owners out there.
PS It's probably worth mentioning that the C63S Coupe normally wears 285/30/R19 rear tyres (or 20" equivalent), which aren't available in the ContiSport 6 range, so I went for the 295/30/R19's instead (after telling my insurers). This might well be helping with the road grip too.

I have just purchased a MY 18 model C63S wagon with carbon ceramic brakes & Dunlop’s fitted..only 2700km on the clock...
1. Anyway, just looking at what the largest recommended tyres are for these and best brand when I come to change..
Mine is currently wearing Amg black wheels 245/35/19 fronts & 265 /35/19 rears..mostly dry weather in Queensland.
2. I would like to add spacers also to bring the wheels out.
Spacer size recommendations also appreciated.
Thanks

I can only speak to the tyres, however I believe the widest you can put on the existing wheels are 20mm wider, but no more than 10mm is recommended and your tyre place will be able to confirm this for your wheels (they are different on the coupe).
You may need to adjust the height ratio to compensate for the wider tyres being taller. If you want to go wider than this, you'll need to change the wheels.
In the UK, you also need to declare any changes to your insurers. Not sure what the situation is where you are, but I would imagine it would be similar.
As for which tyres, I gather the Michelin Pilot Sport 4s are currently rated the best. I'm currently running on Continental SportContact 6, which are very good but I may change over when they need replacing.

I had conti 6 as fitted from the factory, recently changed to PS4S and slightly wider than standard fitment. Much better all around.
The first check has to be your tyre pressures as they tend to come way, way over-inflated from a dealer/service. I run 36psi/34psi front/rear respectively on the 19"/20" satin black coupe rims and that seems perfect. They were 45psi or thereabouts all around from the dealership and felt like ice skates.

It's a complete pain as some OEM tyres are different and some are the same.
I suspect most are the same, but the Porsche OEM ContiWinter tyres I put on the rear of my car seemed to have far more traction than the standard ContiWinters that replaced them.
In general, I wouldn't worry about it!
