235/40 on 18"s here
Stupid dealer tryed to force 225/35 on her and broke her bad dont do that I'm not even sure about 18" period

 

245/40ZR18 front, 275/35ZR18 rear
which needs amg Et offsets to avoid interference with the suspension bolt.
18 x 8” ET31 front, 18 x 9” ET35 rear Rims
you lose a bit of width but give yourself some wiggle room in tire makes if you go with the above size rims and 235/40/18 and 265/35/18 rears.
you don't need Z rated,you won't be going quite that fast.

 

i got a 244/40/18 on my carlsson rims, perfect fit ! et38 9x18

 

Are you also dropped 1.33333 inches

 

Currently 245-40-18 front
265-35-18 rear
H&R sport springs frt and rear with #3 pads front and #2 rear
Mounted on Brabus monoblock five (V) 8.5-18 front and 9.5-18 rear both with 35ET offset.
Car is lowered about 1.7 inch front and back with no rub front or back.
A 235-40-18 is fine all the way around and is a plus 2 upgrade from stock with no issues.
A 245-40-18 will also fit the front with the proper offset ET35 or ET31.

And if you happen to see Oh Lord may I please have my dipstick and boot plug removal tool that I paid you for a month ago. I have not received it yet and am still patiently awaiting a reply.

Regards all.

 

Im running 235/35/19 in the front and 275/35/19 in the rear with no rub.
