I don’t think this is possible with the stock setup. Assuming you’re referring to a C63S coupe/cab, the max you can go on stock rims / suspension is 275F and 305R without rubbing or going beyond the tire width limits of the rims.

I’m planning to get this done on my coupe tomorrow (275/35/19 F and 305/30/20 F).

I'm trying to do 275 front and 315 rear on stock rims (5Spoke version).
Hoping 315 is possible but unsure.
might just do 275s and 305s to be safe.

You need to be more specific with which wheels you have - there are at least two versions of the 5 spoke rims that look near enough the same. The C63S has a 10.5 rear whereas the non-S is 9.5 I believe.

See these two, for example :

coupe S

The width of the wheel may dictate the tyre size rather than if it’s gonna rub.

Let us know if you do upsize as I also have the 5 spokes (10.5 rear version) - what tyre size are you running right now @Granitg ?
