Widest Tires You Can Run on C63S Sedan? Let's Hear it!
Now perfect ware across front and rear tyres after another 18 months, seriously worth fitting these.
As for rear pads, I think I went through 2 sets then upgraded to Porterfield.
Much better life, less dust and little to no squeak.
Search RDO247 for all my posts on upgrades and changes I’ve done over the last 3 yrs.
Hope this is helpful for everyone.

Thanks for the the tips on pads, I’ll check them out. I don’t want to reduce stopping power or initial bite, but I’m not as concerned about those on the rear pads.
Running 295/30/19 in the rear and 265/35/19 in the front.
Have a question:
Originally the diameter for front tyres was 25.8" now 26.3 .
Diameter for the rear tyres was 26.3" now 26".
Originally the rear tyres where 0.5" larger in diameter than the front.
Now the rear tyres are 0.3" smaller in diameter than the front.
I am wondering if this effects traction control? Is traction control calculated by wheel rotation of front wheels vs rear wheels via the ABS?
Just need to work out if I increase the Tyre profile in the rear to 295/35/19 or decrease the fronts to 265/30/19. This will give it the correct ratio front to rear wheel diameter. I feel that maybe traction control kicks in a little to early? But then again I want to confirm if the front wheels have any bearing on traction control. Eg(ratio of front wheels rotations to rear wheel through the ABS)

9.5” front
heaps more grip. 295/30/19 rear
Im using the original rear tyres for the front. 265/35/19
Ideally 265/30/19 for the front. Will eventually change to this size as this will correct the ratio of front -rear wheel diameter. Also will look better.
ive ordered 295/30 for rear and using the stock rear tires for the fronts. hoping it all fits ok find out next week!
This will have a bit of poke im rolling fenders on wednesday to make a bit more space. mine is lowered on H&R too.
I had the above size on my 10.5” BC Forged rears and they scrubbed constantly with rolled guards and being lowered 20mm.
I think you would have to much tyre bulge.
