For the 8", the recommended size is between 225 and 235. 245 is the maximum and 215 the minimum. This is the same for the 8.5" too.

225 is better suited to a 8" rim width and 235 is better suited to an 8.5" rim width, this is for 19" tires and aspect ratio range of 35 to 40.

You should be looking at this the other way around. Check the rim width range for the given size of tire you would like to use, instead of the tire size range for a given rim width. Better results this way. Moreover, tire technology, material and construction changes over the years while the nothing really changes with rim width and the type of bead profile.

Do not put 9.5 and 8.5 combo on the c43 c450 c400
No more conflicting answers if you read through it. This is the general consensus:
8.5J 30ET front
9.5J 40ET rear
225 40 19 will work on 8.5J
255 35 19 will work on 9.5J
If you get the above rim spec, you can upsize to 235 and 265 respectively as well.
This fitment should be very good.

I tried this fitment twice first with 20" rims and then with 19" rims both times the handling changed the car was pushing hard to get to speed and I couldn't reach more than 240kmh with my c400. I returned the wheels and got some oz 8.5×19 with et 44 all around very good looking. Then still not good enough I found mam gt1 felgen 8.5×19 et45 all around and the car drives amazingly 258kmh no problems 0-100 way faster than the wider 9.5/8.5 combo and the fuel economy is better and the transmission and all wheel drive system thanks me every day. So guys do not listen to some idiots who want to sell you wheels to get the money. 4matic needs 8.5max wheels all around. Et 44 or et45 depends from the wheels construction

C450 Rim size fitment
Hello, everyone
I was wondering if you could help me with choosing the right set of wheels for my car. I have a C450 4MATIC. The car is currently on the factory 18 Inch wheels. It is lowered(on coilovers I guess but not entirely sure, because I've bought it this way and I haven't had the chance to ask the previous owner of the vehicle).
The wheels I'm thinking of going with are HAXER HX04F:
19/8.5J/ET40 FRONT
19/9.5J/ET40 REAR
For tires I'm probably going to get 225/40/19 FRONT and 255/35/19 REAR.
My question is would it be a problem to fit these wheels with these tires on the car?
Thanks in advance!
