SL65 wheels on E55




Rafal has 38 offset at rear using 285's giving around 4mm clearance from wheel arch. He says 285's on 31's will get chewed up under compression by the wheel arch. Spec rubber on this rim is 275's (maybe this is the max you can go) and then you will be hunky dory... or so it seems.
I am still bewildered why tirerack and AMG spec 30 & 31's for the e-class. I did not know you had a choice to be honest.
I have a set (19" amg style IV splits 30 & 31 offset with 285x30x19 B/stone re050a's) sitting in my friends garage and we will soon see how poorly they fit.
Please advise if you can find any more info.....

WOW What a difference!

I currently have the SL65 wheels on my car.....I am running 255's & 285's bridgestone re050's.
I found the wheels did not rub until I lowered my car. However, there is a fix for this, I found that moving the et31 to the front and running et30 at the back eliminated the rubbing....you can do this by simply taking the wheel apart(undo all the torque bolts) and reversing the offsets. I also found the handling on turn in improved....perhaps because of the wider track the et31's gave me at the front??
I hope that makes sense???

I have the Kleeman lowering module, the car is in comfort mode while running in the picture. I will take some more pics in sport 2 and with engine off (dumped) and post over the weekend.
i read in your post that you have some CL65 wheels available to you??....I don't think they will work because the CL and S have a totally different offset to the Sl and E?

By moving ET31 to the front you are making the front track narrower, not wider than ET30.
ET30 on the rear will rub more than ET31 ie. 1mm more out.
By undoing all the torx titanium bolts and swapping the centres you have ruined those wheels. Just put them on a balance machine and watch the "Mexican wave"

Firstly your explanation of my wheel offsets is all wrong!....it is true for other wheels but, the original SL65 wheels work on a reverse offset principle! (et31 sticks out more than a et30)So my comment about the track being wider is correct!! (I can take some snaps if you wish)
Secondly, I don't see how I have ruined the wheels by undoing the bolts??.....surely split rims are just that........split rims!.....which gives them the ability to be split???? e.g. some of the guys on this board have HRE split rims which they have had to send back to HRE to be repainted.....do you honestly think they could do this without splitting the rim???......or do all of these people have "ruined" rims???
I did not imply that people should sit at home and split these rims!!!
......I had a specialist wheel place who know what they are talking about do this job for me.......i.e. making sure all the bolts are inserted with a threadlocker and all tightened using a torque wrench to xxNm.
FYI I witnessed all the wheels being balanced and no there was no mexican wave!!!....and so there shouldn't.....these are original amg split rims (not replicas)......there is absolutely no harm in taking them apart provided the correct tools are used!
I agree with what you guys are saying about offsets 100%!....however it doesn't apply to these wheels!
I have a quick way to resolve this.......on one side I will put an et31 (285) and on the other side I will leave the et30 (285) and take a couple of pictures.....it is very clear that the et31 sticks out of the wheel arch more than the et30 hence why the et31 rubs and the et30 does not. Also, the sl65 wheels do have quite a thick center hub (probably why they are so heavy), amg varies the thickness of the center hub to change the offset on these wheels....for e.g. the center hub of the et31 wheel is thicker than that of the et30 (I have seen the et30 and et31 standing on their hubs side by side and the et31 stands higher). The lip size is determined by the J size.....i.e. 9J, 10J e.t.c.
Vadar you are right this method does involve alot of dicking around, but I just had to have these wheels, with the 255 and 285 tyre combo.
I will post the pics in the next couple of days.
No worries as long as you do not lower the vehicle




255/30/19 on 19et30's and 285/30/19 on 19et31's. B'stone Re050A's.
Tyre shop says 245 & 275 are correct sizes... but will see how we go - maybe I can get away with it.
Worst case I put on 275's at back.

Yes Factory SL 65 Rims/Tires with the Stock Size Tires 245/275/19 Car is NOT lowered..NO Rub even with Five adults .....Dont think I Will Lower the car as its my wifes car...
