If you are keeping the stock wheels but just changing tread, the 275's are no problem. I know from experience cause that's all I used on my c63. I had 245's on the front, and I'm sure 255's would also be fine. If you are changing wheels widths, then you you will have to use an offset calculator to determine clearance.

with 275/30 being smaller rolling diameter, would you have a tendancy to spin the rear wheels more? ~ less performance?
(ive experienced this in the past when going with wider tires, and smaller rolling diameter, it sucked)
what about 275/35?

A 275/30 is .5" greater than the stock tire diameter and is probably as big as you want to go.

A 275/35 is a full 1.5" greater diameter than stock. I think it will be too much for more than 1 reason such as rubbing, speedo error (6%), variance from front tire diameter and perhaps ecu tolerance.

oh didn't realize we were talking about the 19" wheels. so are the stock 18's vs stock 19's both using 255/35 on the rear? that's a full inch difference in rolling diameter then? that's weird woild they not have different performance characteristics? or is it engineerd into the car for each size.

oh, that makes more sense...
so a 275/30 on the stock 19" would prob be cool then...
another thing,
does anyone know if the AMG black series wheels/tires (i believe a 285 on the rear) can be ordered on the regualr AMG/w/AMG package?
would they fit?
am about to order one and i don't want the skinny 255's on the rear...

I have P40's on order but the salesman asked me about offsets, which i am unsure about. He recommended 19 x 9.5 " with ET43 in the back on the Mich PSS 265/30's. Front they recommended 19x8,5 ET 40 with 245/35 PSS. Is this a good setup? Would appreciate a quick answer! Thank you in advance and sorry for dumbass noob questions

If stock is 9" et54 for the rear, then that setup is going to stick out an additional 17mm just with the rim. Plus whatever for the tires which is negligible. I'd grab a ruler and see if you like that setup.
