C238 4Matic - 20" wheels question

Hey all, I have a question on rims/tires for the 4Matic version. I have been told by my local INDY that I shall be very carefull not to mount anything not 100 pct per Mercedes specs, in order not to damage the 4Matic !

According to Mercedes original standard, I can mount 20" wheels, provided they have below dimentions:

Front: 245/35 R20 95Y XL 8Jx20 ET43

Rear: 275/30 R20 97Y XL 9Jx20 ET53

On top of that, MOE or MO approved tires (meaning Pirelli PZero or Yokohama Advan 105)

My question is, do any of you have good experience with 20" rims with slightly different specs? I am thinking og mounting
Front: 245/35 R20 95Y XL 9Jx20 ET37
Rear: 275/30 R20 97Y XL 9Jx20/ET37


Is this possible / recommendable without risking jeopardice 4Matic ?

Good input very welcome

And thank you all for a great forum

Hi, I have that spec of wheels on my C238, they were a standard fit on the car when I bought it in 2018. I have not been aware of any problems.

Hey,

See attached specs for wheel/tire combination.
Make sure the wheels are A213XXXXXXX....I tried to use 20" wheels (ET43) from GLA45 AMG and didn't clear the front brakes. I had to use 15mm wheel spacers what screw up the wheel geometry.
Have a look at https://www.wheel-size.com/calc/?whe...cl=30mm&sr=0mm for more info.
