Post your C450 with Aftermarket Wheels
19x8 et45 (with 15mm spacer)
19x9.5 et51 (w/wo 5mm spacer)
245/40 F. 275/35 R
OR
235/40 F. 265/35 R
Leaning towards the beefier tires and increased diameter that comes with them (in margin of acceptable difference).
I am a new owner of a C450 and am in need of a summer wheel and tire setup. I have been through this thread trying to understand all the fitment questions. I'm terrible at understanding the mechanics of it all.
I have found some wheels with the following specs. I think they will work, but can anyone here confirm?
- F 19x8.5 et 32
- R 19x9.5 et 42

the front will work with a 245 tire, but likely not more.
Use this:

basically - find set-ups that work and stock measurements to give you an idea of what you want.
so 20x10 et55 fits the rear nicely. The set-up you have questioned about is 7mm more aggressive and would poke past the fender without rolling/lowering/dialing in camber
tire size also has a huge roll in the equation. So you typically want to compare the same fit that you will be applying.
So, you can run as skinny as 255 (even more but then you're dabbling in that stance life fitment) on a 9.5 without an insane amount of stretch, the OEM fit is 255 on 8.5 (which is considered more of a square fitment).
Even tires vary from brand to brand and those specs can be looked up online too.
This all starts to boiling down to more advance users/fitment.
Basically, I would recommend 9.5 @ et50+ to be safe for the rear with a 265. If you want to fit a 275 you'll want to throw more allowance to fit the more bulgy sidewall.
Then you want to make sure the front and rear fitment make sense as a package. Like, visually, running a 245 on 8.5 up front will look goofy as hell if you're stretching a 255 on a 9.5 out back.

I mean, not even by special order?? Sh--. On a brighter note, at least an E400 Estate could be in my future.....thank God Almighty.
[QUOTE=BMWMB71;7126822]I have 10jx20 ET45 in the rear, and the wheel does not poke, but it is the limit!
Wheels in front are 8,5j ET 42 with 12mm spacers.
Wheels are Ispiri FFR6.
No rubbing issues at all. ;-)

I'm new here - purchased a C43 AMG coupe a few weeks ago and just in the process of perfecting it for myself!
So, I'm looking for some nice rims + solid winter tires, hoping to get a good deal entering summer. I'd prefer at least 18s - but 19s would be nice as well - doesn't need to be anything too pricey because they'll just be for the winter months obviously.
As for the tires, I've heard that Michelin X-ice Xi3 or Bridgestone blizzaks WS80 are both solid choices. Thoughts? Costco sells them for about $840 CAD for a set. Is that a decent price?
Thanks for all the help!

I suggest getting someone else's opinion as I wouldn't take my word on it cause I am certainly not an expert on all this wheel/offset stuff. Just learning myself as I just bought wheel this week.
All my research is showing this but it's usually always showing older cars up to 2015 at the latest. I can't find anything that confirms that 2016+ cars still use that. I'm sure they haven't changed it but I just want to be 100% certain.
Want to order these for my CH-R's that I'm installing next week. Thank you in advance

I linked those to you originally with choosing proper spec for your application.
