If you have Sports brake calipers, I think the smallest wheel size that will fit over calipers is 17 inch wheel.

 

[DMK/Happy]

Seems 17 inch rims are the correct size , could I go to 18 inch seem to be more on offer after I had a search? Thanks everyone for advice.

Are you after genuine MB wheels of aftermarket ones??

17's are a good choice cheaper & more choice of tyres than18", & a better ride.
I have 18" on both the E class & SLC, but 17" winter wheels. I prefer the ride on the 17" particularly on the SLC.

That is a really interesting trial example.

On my W203 I had 8x17" ET35 all round fitted with 225/45 R17 front and 245/40 R17 Rear tyres, no issues at all

Seems like a good recommendation to me,pesently. Thanks

I also have 225/45 R17 (Crossclimate+) on my S203.
Great tyres IMO.

Interesting proven trial history,at the moment 225/45 R17 front and 245/40 R17 Rear are fitted on the C220 S here. Thank you.

Shame that Crossclimate are not available in 245/40 R17 which appears to be a particularly German size otherwise I would have gone for that too.

I had the alloy rim width checked at the tyre shop 8.5 J rear 7.5 J front hence the difference in tyre sizes,,245/40/17/8.5 J rear,with 225/45/17/ 7.5 J front for the C220 S recommended spec. ..

Yep, it is the recommended size. A 225/45 does fit though and is a permitted size. The actual difference in tyre contact is not worth worrying about at around 8 sqcm and is still around 20 sqcm greater than the 205/55 R16 that were fitted as standard on mine.
17" are normally fitted to clear the 'sport' brake callipers on standard models or for cosmetic reasons

Unless you want something specific, best to stick to those recommended sizes.

I had the 225/45/R17 all round on my w203 coupe.
I really liked not having a staggered width set up as it meant at new tyre time, I could rotate the tyres and always put the new tyres on the slowest wearing axle. This means the heaviest wear gets taken out of the oldest pair of tyres, and that means you don't have a set of old tyres sat on a slow rate of tyre wear axle for 10 years.

Some say you should always put the new tyres on the back for safety, but soon those new tyres will have less tread than the old tyres on the front axle. So in my view that is less safe as you are retaining old tyres for a long time. Unless of course you rotate the tyres every 1,000 miles to get even wear across the two pairs, but who can be bothered with that? Not many.

Michelin, Pirelli and GY say new on the rear with a "square" set up so there must be something in it

Yeah, sorry, wasn't very clear.
Most cars will wear most heavily on tyres on the front, and in those cases, new tyres on the back is the right move. So new tyres on the back will absolutely be correct most of the time.
But if for whatever reason you are in the minority and get heavier wear on the back (and you have a square setup), my personal choice would be to put the new tyres on the slowest wearing axle (which would be the front in the hypothetical example I was trying badly to make) so that you don't continually put new tyres on the same axle and have old tyres never moving on the slow wearing axle.

In reality, I've seen a lot of people with front wheel drive cars needing new tyres on the front (obviously the heaviest wear) and they end up with 10+ year old tyers on the rear axle and then a blow out on the motorway. In that example, I would move the older less worn tyres from the back to the front, and then new tyres on the back.

OP, really sorry for the slight derailment of the thread.
I was simply trying to highlight the benefit of a 'square' wheel set up, that being you can rotate tyres come new tyre time.
