What size are your front tires?

Axel Notrose

Isn't the 19" OEM wheel for the 2018 E400 only 8" wide?

Assuming they're correct, you wouldn't be able to fit a 285 wide tire on an 8" wheel. You'd need a 9.5" to 11" wheel.

Assuming the standard 245/40 R19s on the front, a 285/35 R19 would be very close to the same outside diameter, which is good, but I'm thinking that large a width would be better mounted on 9" or 9.5" width wheels. OEM wheels for the E are 8" wide. You should also check the actual tire you are looking at getting. For example, a Goodyear Eagle F1 Asymmetric All-Season tire in 285/35 R19 requires a wheel width of 9.5" to 11".

I want to beleive that the rear AMG wheel size is at Least 9". Does anyone have knowledge of wheel width of a AMG wheel on a E400 2018.I measure it from outer rim to outer rim it was 9.5". Yes I beleive the correct way to measure is from bead to bead, that looks to be 9".

Only if you have AMG line rims, otherwise the rear rims are not wide enough. On my AMG line e450 Cabrio it has 275/35/19's. On the non amg line the rims would be too narrow and you won't be able to get that size tire on it and even if you did mange it would seriously curve in and you'd wear right down the middle of the tire pretty quickly.

Here is a pic of my wheel (19"), would you say this is a AMG line rim, if so do you believe a 285/35/19 tire would fit this rim? The tire on that rim is a 245/40/19

2012 merc amg

Same wheel as my amg line. On my wagon the wide tires would not fit. I think they are just 8.5 inch rims. I can’t really tell much of a diff in handling from the wide vs stock tires.

Cruiser 7

Ok, thanks so much.... So new rims then? Any suggestion where to look for stock looking AMG 9"-10" rims. Would only like to change out rears, and keep the fronts as is.

Sorry I was unclear in my previous post, that rim in the picture IS a AMG line rim, I believe those tires you listed at the top of this thread would fit but one thing to be careful of is if you have 4matic you want to make sure the front tires and the rear tires are the same diameter. I know with my AMG line Cabriolet it came with 245-40-19 front and 275-35-19 in the rear so those sizes are similar diameters . 285-35-19 as you listed would be a smaller outer diameter I believe but you could double check on a chart they have on www.tirerack.com I assume you have the 245-40-19 on the front. This being the case it could damage your 4matic drive system having dis-similar tire sizes. If you car is just RWD it just means the car will sit a little lower in the back than the front.

The wheel you show is a 19" AMG-line wheel, that is, a wheel, 8" wide, designed to be used on a non-AMG car. Currently, most AMG E-Class cars have 20" wheels, but there is one option, RTE, which uses the same tire you have on the front, but goes to a 275/35 R19 on the back, using 19" wheels which are 9" wide. This is a currently available option on AMGs:

245/40 R 19 on 8 J x 19 ET 20 Front (your current wheel and tire)
275/35 R 19 on 9 J x 19 ET 49 Rear (new wheel and tire)

Surprisingly, none of the current AMG E-Class wheels are styled like the non-AMG E-Class AMG-line wheels, so I don't know that you will be able to get matching, wider 19" wheels to match your current wheels. While I understand you wanting to use the current wheels, and use MB OEM wheels, that may not be possible, and get the wider tires/wheels you want.

The full-AMG type option would be to trade out all wheels to 20", and there are two groups of sizes available should you wish to do that:

245/35 R 20 on 8 J x 20 ET 43 Front
275/30 R 20 on 9 J x 20 ET 49 Rear
or
265/35 ZR20 on 9.5J x 20 ET25 Front
295/30 ZR20 on 10.0J x 20 ET55 Rear

Before you poney-up for 4 new OEM MB 20" wheels, you may want to check price, styling and quality of after-market wheels. Some of the look /very/ nice.

Like I said above my E450 Cabrio has a wheel that looks like that one which has 275-35-19's on the rear. I suspect the front wheels are not as wide as the rears which use a 245-40-19 inch tire. But they do make a wider AMG line 19 inch wheel otherwise my car would not have come from the factory with 275 wide tires on the rear. I do notice that the AMG line wagons and sedans have 245's all the way around so chances are this rim shown is narrower than my Cabrio rear wheel which looks the same in thinking about it. I believe only the Cabrio and Coupe AMG lines use the wider rear tires. The disadvantage is being staggered you can't rotate the tires, you could from side to side but that does not do much good.

rraisley

As noted elsewhere, real AMG model wagons and sedans all have wider rear tires. Standard E's, with or without AMG-line wheels, do not.
It's been my understanding that you NEVER rotate a radial tire from one side to the other, but I do see a few sources say it's okay under specific circumstances (like FWD only, which we don't have). Plus, many tires today are unidirectional, so they can't be changed side to side.

mercedes.fan

It should fit as the amg line 19 inch are staggered (at least on mine) with 9 inch wide rims and 275 tyres. Assuming you also have a staggered setup 285 should work fine.

2012 merc amg

Only amg line coupes and cabrio are staggered at least in the USA. Sedan and wagon amg line are not staggard.

Cruiser 7

Yes it's a 4matic , Just a question, Why go to a 20" wheel? Would these 265/35/20 on 9.5J x 20
295/30/20 on10.0J x20 Fit under my 2018 E400 4matic
P.S what does the J on the wheel size stand for (offset?)
Sorry for being a knucklehead, also which chart do I look for at Tirerack.com

2012 merc amg

I generally just look on the specs chart on tire rack. Heres an example of a Michelin https://www.tirerack.com/tires/tires...omCompare1=yes just click on specs at the top of the page and it will bring up the sizing chart. Keep in mind if you did switch to 20 inch rims you'd loose some ride quality.

If you look on the size you mentioned at the beginning of the thread the 285/35/19 it has a overall diameter of 26.9 inches. When you compare that to a stock front tire size of 245/40/19 it is 26.7 inches, so very close but not exact. Not really sure if this would be acceptable for the 4matic or not being off just a tad bit as it is. Since that rim you showed more than likely came with a 245/40/19 inch tire it more than likely is too narrow but if you were able to get a pair of rims that were used as the rear wheels on a cabriolet or coupe amg line those19 inch rims would be wide enough for the tire you mentioned. All in all though, I'd say it's probably not worth it and your probably best off just going with the stock size on your stock rims. My wagon seems to handle fine with the more narrow tires and cant tell much of difference between it and my Cabriolet with the wider rear tires. If you had those 285's already might just be best off selling them and put the money towards a new pair of 245's.

First, I was looking at only currently available E-Sedan/Wagon wheels. Other wheels (like from the Coupe or Cab, which usually have staggered wheels) might work fine, but I didn't know if they would or not, so didn't recommend them. With the style wheels you have, which are AMG-line non-staggered for non-AMG E-Class, wider wheels are not available. For AMG models, all wheels are staggered, so wheels would be available (you specified you wanted OEM MB wheels). AMG Sedans can use one 19" staggered set or two different 20" staggered sets (which I outlined above). The AMG Wagon only shows 20" staggered wheels available.
They should fit fine, as they are available on both the E Sedan and Wagon.
I'm not sure, but I think that's the bolt pattern. I'm thinking the last couple numbers (ET 40, ET 43, etc.) might be offset.
If you enter your tire size here (https://tiresize.com/calculator/) it will show alternate sizes. You want your tires to be closer than 1/4" in outside diameter, the closer the better. Using standard sets, as quoted above, will always work out fine.

Hey, All you people ROCK, Thanks for all your help and info!! .... I wanted (hoped too) get wider tires in the rear only (mainly for the look, not so much for performance). But its apparently it's not THAT simple......So bummer,,, Stay with what I have???? My hope was to stay with 19" wheels for ride quality. Love my 2010 E350 Look. A little downward rake look ,, wider tires in the rear, wheel wells all fill up.. looks great....Trying to do that with the E400, What happen to MB style ? Wish they would go back to sharper body lines style they had before .MB body styles now are too soft. (my opinion) Again THANKS, Drive Confidence.

You could get new aftermarket wheels on all four corners, thats what I did with my Wagon, I got the Mandrus 23 wheels in 19 inch. Sharp looking wheel. I just got the Gun Metal Mirror Cut finish to keep the price down, they were around 300 per wheel, so 1200 total. Interesting the tire that matches up exactly to the rear tire number you gave, 285/35/19 is a 225/50/18, they both have a Outer diameter of 26.9 inches so that would be fine for the 4matic drive system and give you a better ride as there would be a sidewall meat on the front wheels. So you'd be getting 9.5 inch wide rear 19 inch wheels and 9 inch wide 18 inch front rims. The fronts being a little bit more narrow would give the appearance of the rears being even wider plus you could get a lower offset number that would kick out the wheels a little bit to give the car a little bit wider of a stance, thats what I did with my car although it's hard to tell from the side profile pic here. I think mine was 36 ET. Factory calls for 43 ET at least on the 213's.
