I'v got a c220 (w204) with 225/40 front and 255/35 r18 rear. I'm planing to get 19 " wheels (8,5") but not sure on what tires i should go with. I'm thinking to go with 235/35 front but i have no idea what to get for the rear. I don't want to go under 255 in the rear but not much over either. So if u guys could give me some tips that would be great
Forgive my ignorance as it's probably just a spelling for a different language, but what is "tyres"?
However, I'm not sure how to answer your question. I normally just get what ever Michelin the tire place has, and that will fit on my wheel. All four matching of course, because AWD... lol

I'm running 19x8.5" (235/35) & 19x9.5" (265/30) on mine. Tires are Hankook Ventus Evo 2. I'm lowered on H&R Super Sports. It'll depend on the offset of the wheels you are looking at if they'll rub or not.

Well my car is not lowered the only thing is that it has the AMG-packade. what offset should i go with do you think, 35 or 45
I have Continental ExtremeContact DWSs on mine. 235/35, 19" rims, not lowered.
Drives really well on them, good in slush, and snow. Handles wet highways and dry roads with ease.
To get to your question - I went 235/35 all around - looks really nice, IMHO.
Advice on tires for 2007 E-350 4-Matic 245/40/R18 vs. 245/45/R18
I need suggestion on tires which I will be replacing on 2007 E-350 4-Matic which currently has Continental ContiPro 245/40/R18
I am thinking of going with 245/45/R18 Michelin X-Ice. This tire is a little taller 40 vs. 45 and I want to raise my car a little bit. Also I am getting a very good deal on these brand new tires which has excellent reviews on snow/ice.
Any suggestion or concerns if I go with 245/45/R18 ; 100 H instead of OEM ?
People talk about strain on 4-Matic transmission and odometer not being accurate if your replacement is not the OEM specifications. Are these things true ?

Going to a larger or smaller diameter tire than OE will give you speedometer (and odometer) errors. To see the effect changing your tire size would have on your speedometer reading, check here: http://tire-size-conversion.com/spee...r-calibration/
If you have full-time AWD it is usually okay to run a staggered set-up as long as the tires all have the same (or very nearly the same) rotational speed (revolutions per mile). The OE tires on my '13 C350 4-Matic coupe are 225/40-18 fronts (804.6 revs per mile) and 255/35-18 rears (807.1 revs per mile) and are not a problem for the 4-Matic system.
Some full-time AWD system are less tolerant of differences in rotational speeds than others. IIRC the ATTESA system in my '10 G37x started to have problems if there was just more than about 3% difference in the rotational speeds between the front and rear tires. I don't know what the threshold for rotational speed variance is for the 4-Matic system before its starts to become a problem for it.

Reason: Added more information
I am not going for a staggering setup, instead I am replacing all 4 tires in same size but instead of going with 245/40/R18 , I want to go with 245/45/R18
So I am only selecting a tire with higher "Section Height" of 45 instead of 40.
Otherwise all 4 wheels will have same tire size.
My questions:
a) Is it OK to put a tire with slightly higher "Section Height" ?
b) How much longer (in diameter) will be 245/45/R18 vs. 245/40/R18?
c) Any disadvantages or strain on 4-Matic transmission ?

a) The larger 245/45R18 tire will fill out the wheelwell by an extra 12mm which should be acceptable and not cause rubbing in most circumstances.
When speedometer reads 60 mph the actual speed will be 62.2 mph (3.7% faster) with the larger tires.
b) 245/40/R18 is 653 mm (25.7") in diameter 245/45/R18 is 677 mm (26.7") in diameter
c) There should be no significant added strain on 4-Matic transmission with the larger tires.

Does this also means that my odometer will show more (>3.7%) than actual mileage I will drive ?
Also does it effect the working of TPMS system?
Don't want to run into an issue with TPMS system.

I believe the odometer will show 3.7% less miles than you actually drove.
so if your 4matic came with a staggered set up, it is okay to use a non staggered set up without affecting anything?
That's correct. Most AWD cars have a non-staggered set-up from the factory (including my '10 G37x, '10 S5, '11 550ix and '12 Murano SUV).
A non-staggered set up on a 4-Matic won't be a problem either.
Finally got new Michelin X-ICE 245/45/R18 100H installed today. Really liked the drive and handling
Initially ran into an issue with "Brake Wear" message in the display, but fortunately it was just a bad sensor connection and swapping the sensor with a new one resolved the issue.
I don't drive a whole lot and planning on using the same tires all year around.
Are there any advantages/negatives if I use the same tire in summer as well ?
I won't be driving more than couple of hundred miles during summer months.
I understand.
I don't think driving a few hundred miles during summer months on winter/snow tires is going to be an issue. The rubber compounds in winter/snow tires are optimized for low temperatures, but I don't think the high road temps in summer months are going to damage them with just limited use.
Maybe someone else here with more tire knowledge than me will have a different opinion.
