Help! 2014 CLS63 SAMG 4matic with 245/40/19 tire
I have a 2014 CLS63 SAMG 4matic. My wife is so angry with me because the car is so hard (not soft). I decide to change 245/40/19 tire for front but I do not know what size of rear I should go for, because my car is 4matic. Anyone can help me with this please.
Thank you so much
