hey everyone
so my new rims should be here today, last night i ordered H&R springs and so all thats left is for me to find some tires.
I am not sure though what size tires i should go with. given that i will have H&R springs, and my rims are 18x8.5 and 18x9.5 what tire size do you all recommend i should go with.
any help would be greatly appreciated! and i can post pics this weekend when hopefully everything is installed if u guys what :-)

As per Mercedes Benz Manual, here is the tire size and offset recommended for 18" wheels:

225/40 ZR 18 (7.5Jx18 ET37) Front
255/35 ZR 18 (8.5Jx18 ET30) Rear

Since your rims' width are wider by 1 inch, I suggest you increase the tire width also.

235/40 ZR 18 (8.5Jx18 ET37) Front
265/35 ZR 18 (9.5Jx18 ET30) Rear

as late as your reply was i really appreciate your help..since no one else cared to help out. i ended up putting 225/40/18 and 255/35/18 and so far everything has been good.

Sorry for helping late as I only saw your post last 7/3. Anyways, it's good that the tire size you picked worked out with your wider rims. Just curious though: did your wheel's rim edge stick out since the tires are narrower than the wheel's width? How about posting some pics?
