Anyone have the offset specs for the optional 16" x 8" rear alloy wheels that were available for the 96-99 models. I know the standard wheels were 16" x 7 1/2" with 51mm offset. Best I have been able to determine the 8" optional wheels for the rear only were around a 46mm offset. I want to stay with the original but fill up the wheels well a bit more.

Theres no other rims standard on the 140 other than the preface and the facelift as above. A pic might help if you have one

The only 16x8 i can think of is this, which look like the 92-95 version


Theyre standard for the 124 500E

You mean these?



Theyre the same specs 16x7.5 ET51
Have to be what he is talking about. They are on my car right now, ( HOW I miss my 19 inch AmG Monoblocks. Kinda). These litter the landscape. Even a quick search on E
bay will reveal a set and the offset. These wheels should lend no mystery.

Wheels - old thread

Hi - wonder what solution you found for your car. I want to do the same thing on a 1999 S500 - fill out the back tyre to lessen the "bulky" look of the car. The 8 hole are my favorite as mentioned in the thread - 16x8 may be difficult to find. Were you able to get wide enough in the back to balance the look ? Other options to fit properly ? Just curious.

Is the factory tire size 225/60/16 or 235/60/16 for the factory non-AMG wheels as in the pictures below??
I am thinking to buy Sports Edition ST3 with 235/55/17 but want to make sure I won't have any rubbing or ABS/ASR issues. Tire rack recommends 225/55/17 for the 17" and told me i can go also with the 235/55/17, any recommendations?

Hope this clears it up. Unless Im missing something




Thanks to Syljua (right?) for the pics

I think I found some info on this, based on Tires.com and Tirerack, the V8 models came with 235/60/16 and the I6 was 225/60/16.

I put it through a tire calculator and it was smaller diameter but I see my mistake... in that I put it as a 235/65/R16 and not a 60... you should be fine.

I have run 255/45/19's and they're just fine no rubbing or anything.

Now after more research about wheels and tires, notes like below from @bayhas in another thread makes me a little worry about the over all performance of the car.

1- The speedo reading is the last thing I am worried about.

2- the 1.8% is difference in circumference so no further calculations are needed to bring the number further down.

3- the diffrence in the circumference of tires, changes many aspects such as:

-shifting points
-torque
-torque curve and delivery
-braking character
-max speed
-rpm at certain criuse speed.
-Gas consumption
-ESP, and gyrometers will confuse the crap out of it.
-wheel arc clearance (not an issue with W140s, all have same chassis)
-speedo reading (cosmetic)

4- notice that I am not saying do not install after market wheels, I am saying MAKE SURE YOU STICK TO THE FACTORY CIRCURFERENCE.

5-other than the tire circumference, get the rim size you like, with the tire width you like.

6-your speedo is more accurate at measuring your momental velocity than your GPS, have you tries to deaccelerate really quick while monitoring your speed on the GPS? ever noticed that it takes the GPS couple seconds to set to 0 after you have completely stopped?

7-The AC/DC and pulse modulation IC that takes the pulse of the wheel speed sensor AC pulse, and converts it to DC that move the needle is not adjustable by the dealer, at least not through any dealer scanner.

8-if you have a problem as in why 320 needs 225/60/16 (or any other tire with 83.7" circumfrence), and 400-500-600 take 235/60/16 (or any other tire with 85.1" circumfrence), you are barking at the wrong tree... contact Mercedes Benz LLC, tell them they are stupid for going through the hassle of making to tire size lines available at the dealer and factory, and that you have a great solution of installing any size as long as the car "rolls" and tires dont touch the body...

If I put 245/50/17 on the S320, will that tire width cause a lot of road surface resistance due to the wider 245 tires versus the stock 225?
