Wheel tyre combo question (new w221 owner)

Hi all,
New to the w221 have owned couple of w220 s class's, finally made step up and can not believe the difference. My question to you is that I have standard 18's on which look lost! now I don't want to go huge and ruin the ride but I want to fill out those big arches so thinking of 19" lowering a little and going either 255 front 275 rear and either 45 or 40 profile??.
So
#1-what is best offset?
#2-what is best profile?
#3-what is best width tyre?

Many thanks in advance of your wisdom

Welcome to the forum. Wisdom here is in short supply, but we make up for it in sarcasm and mockery.

IMO, coming from two prior 220's myself and being wheel-obsessed, the "right" look for the car is staggered 20" with the OEM tire sizes, (255/35 front and 275/35 rear) and low offset wheels or OEM offset wheels with spacers. That fills the fender wheels without compromising ride quality. I think drops are dicey business, and when the car is low enough to make a difference it's too low to preserve the ride.

I'm on OEM S63 20" staggered with 20mm rear spacers and 15mm front, for effective offsets of 24mm rear and 29mm front. That's as close to flush as you can get without rubbing issues, or having to roll the fenders. You could also do aftermarket replica wheels at the standard 35mm offset. Not as aggressive but no need for spacers.

Thanks for reply Mike,
so what were the et on your wheels before spacers?guessing about 44mm? as the smallest hubcentric spacer is 15mm (I'e with a ring for rim) so what would be ideal et for filling arch out without spacer?
Or et front and back to use 15mm hubcentric spacer to fill out arch.
Sorry for all question but starts to melt my brain!!

Cheers Nick

Depends on the weather
This is what replicas look like: 20x8 and 20x10 at 35mm front and rear. I am running thicker tires though - 255/40 fronts and 285/35 rears.

That looks really nice, I'm looking at some wheels called "Jantes vertini Monaco" they are 19" concave front 8.5 rear 9.5 so say I put 255 40 front 275 40 rear what et would be best F&R

Chris the swede on here has those wheels in 22". I think in 19" they may not look right because of the concaveness of them?

WHPH28 thanks for quick reply, where i live is a lot of country lanes and pot holes so going 20 is a bit much I think. My w220 was on 19" and that really detracted from the ride.
Have you got a link to picture of Chris the swedes ones please.

19" are probably too big for a 220. The base wheel was 17" and the AMG package were staggered 18". But everything moved up two inches for the 221, and the ride on OEM sized AMG 20's is still very compliant. I had 19's on my 221 when I got it and the 20's didn't feel much different. But there is less sidewall for potholes and stuff.

I'm only on spacers because I already had the OEM 44ETs. I'd avoid spacers if possible and just find aftermarket wheels with a lower offset. Less rotating mass and opportunity for vibration issues. You can go as low as 24ET rear and 29ET front. Those aren't going to be available as a replica wheel, you'd need to look for those in an aftermarket.

If you did go replica at 35mm all around, 10mm spacers on the rear would put you flush at 25mm, and 5mm front spacers would be flush at 30mm. (Don't sweat being a mm off, it's a sliver.) Get good spacers from HR Trak, not the cheap EBay stuff.

Thanks Mike, Sorry for all the questions. Right think I'm going to go 19" because it's cheaper to find out they are wrong rather than with 20"and tyres so can upgrade I if don't like them?
That's my train of thought anyway!
So my question to you is (last one I promise) can I go 255 45 19 & 275 45 19 or do I have to go 255 40 19" & 275 40 19.

Many thanks
Nick

I don't mind the questions, but they are going to earn you a quick tutorial on tire sizing

I think you can run either profile, but the 40 sidewall ratio tires will look better (less "chunky"). Sidewall is reflected in the tire size as a percentage of tread with. So a 255/40 has a sidewall that is 40% of 255mm = 102mm sidewall height.

102mm = 4" sidewall height on the 255/40/19. That's a lot of sidewall. The 20" version (not surprisingly) is about a 3" sidewall. That's the size of the sidewall on my car.

255/45 would give you 45% of 255mm = 114mm 4 1/2" sidewall height.

So the difference is an extra half inch of sidewall under the car between those two sizes on the front. The sidewalls on the rears will be marginally taller relative to the fronts , since the tread width increases but the sidewall ratio remains the same.

275/40 (275X.40)= 110mm (4 3/4")

I totally get the idea of playing it safe on the 19's, but if the net result isn't the look you're going for, you're going to be bummed. A 221 is perfectly content on 20's, but if you're set on the 19's do the 40 profiles.

Don't do a wheel with a lip (like the Vertini) in a 19". The lip eats up an inch of visual diameter and will look like an 18". In a 19" you need a wheel where the spokes extend out to the outer lip. Look at something like the Niche Apex or Niche Milan.

Hi,

How did you deal with the speedo error? I would have thought that these tyres were slightly higher and would cause an error in speedo reading from 1 to 4 MPH from 50 to 150 MPH.? Thx
