Hi Y'all: Quick question regarding my 2015 C300 4Matic that came with 19" AMG wheels.

My fronts are 225/40/19 and rears are 245/35/19.

My question is, can I throw on 225/40/19 tires to the rear? If yes, would this create any concerns or issues? Such as speedometer inaccuracy.

Thanks in advance for any comments.

You can see the differences here, it is possible but in my opinion I wouldn't do it because if the tire width ends up smaller than the wheel it will not only look bad but it gives less protection of the wheel from curb rash . Also will affect performance in some ways due to the tire stretching to fit the wheel, so some shops refuse to install smaller tires that don't "fit properly".

As @BayAreaAMG stated, you will probably need to get front rims for the rear since the width is different. Otherwise 225/40/19 all around would enable you to do a proper tire rotation to get the most wear out of the tire set.

Thank you for the information, it is really helpful.

That answers my question, I just wanted to know if the front and rear rims are the same width, if it is I wanted to put 225s all around, but it seems that they are different, in this case I will just go with the factory original spec.

Front rims are probably 7.5” width and rears 8.5”

^ CoffeeBreak is correct. Offsets are different as well.

Just changed my staggered 18" AMG wheels to aftermarket square for the winter.
