A 2011 e550 tire question
MB heads, hello.......
No, still not here, lol....
Any '11 driver willing to give me specs on tire compatibility with
18x8.5 in front and 18x9.5 in the rear? I think it's a bit different for
the 4matic though........so any 4matic info would help......
I've looked on the mbusa and only found the regular sizes for the sport
e550....and can't tell for sure if I can use the same tires....or get wider tires in the rear because of the wider wheel?
kind of confused...
any insight would be helpful..
thanx

You can only use a non-staggered wheel setup on the 4-matic. Otherwise, you risk blowing the transfer case due to dissimilar wheel diameters.
Sport 4MATIC: (8.5 x 18.0 front/rear)
Sport 4MATIC: (8.5 x 18.0 front/rear)

You definitely do not want the bill of a blown 4-Matic transfer case on your hands. 
With 4-Matic, definitely stick with a non-staggered setup.

glad I asked
thanx for the quick replies gents....
so if I exchange the two 9.5's to have 8.5's all around
I should be okay......I wish the dealer would have picked up on this when I explained
it all to them.....but whatever........
should I even get rims (that are lighter than the stocks) if I have 4matic? hmmmm....
thanx again

What you need to be concerned about is that the overall diameter front and rear stays nearly the same, staggered or not. The preference is between 0 - 2% difference max. And that is calculating the worst case with one tire at 2/32 tread and the other at 10/32 tread.

Hyper, since you are getting the 4matic and YES overall diameter is important, you can't get staggered setup otherwise you will fry your transfer case(aka differential). As a owner of a auto shop, I see this very often and their owners are

Huh? You are a moderator right? I question your knowledge on tires! Try www.google.com It is a great starting point.

You might want to go over to the W204 forum. MB fitted staggered setups OEM on 4-matic.

Only MBs - the best or nothing
Now why C300 4matic "sport" uses substantially differen diameter tires front and rear is still unknown to me. MB fits 225/45-17 front - 25" diameter for most tire brands and 245/40-17 rear - 24.7" for most tire brands. This is 1% difference, so since most staggered sizes for E-class yeld much less than 1% difference, for example 245/40-18 and 275/35-18 are only 1/2%, then IMO there is NO reason (other that what MB dealer tells us) why properly matched staggered tires and wheels can not be used on all other MB 4matic cars - E, CL, S, ML.

You have to have a % factor to account for changing the tires on just one axle. Using 245/40-18 as an example: front has 2/32tread and rear has 10/32 tread -> front = 25.2" and rear = 25.7" diameter. That is ~2% difference between front and rear. That has to be accounted for in the design since you can never guarantee equal wear on tires.

Personally, I change tires (all 4) immediatelly when tread reaches about 6/32 (fronts usualy go firs on AWD cars). IMO tread below 6/32 increases chance of hydroplaning. I take this very seriuosly. I get only one chance to live.
