Do these wheels/tyres fit? Read this post first!

[LostKiwi]

Thanks all. This is super helpful. So my wheel size if 17" and the options I have as per the fuel cap filter are 16", 17", 18", 19" and 20" with OEM recommendation of 17".

What do I make of this table (screenshot) below ? It says that the best option for W213 is of course the OEM recommended 225/55 R17 followed by 245/40 R19 followed by 245/45 R18.

I do not want 19" so will choose between:
1). 225/55 R17 all around (for better ride quality) OR
2). 225/55 R17 for the front and 245/45 R18 for the rears in a staggered setup (if the preference is 'looks' of a wider/broader rear)

So if the priority is ride quality, 17" all around is the way to go?

Lastly, any reco b/w Michelin and Pirelli (and make/variant) from first hand experience?

That chart is solely looking at the difference in rolling radius and not at anything meaningful to ride quality or even fitment.

As already mentioned do NOT mix rim diameters front and rear.
It's either 17" all round or 18" all round.
You can have wider rear rims and tyres than fronts but stick to manufacturer sizes unless you want to invalidate your insurance. Mercedes do offer a setup with wider rears than fronts (called a staggered setup as already mentioned above).

So OEM is 225/55x17 all-round.
Staggered is 245/45x18 front and 275/40x18 rear on 18x8.0 front rims and 18x9.0 rear rims.

I'd recommend Goodyear Efficient Grip 2 for an excellent tyre. Scroll down for the price.
The price you see is the price you pay, fully fitted at your home or local fitters.

Ok. Much clearer now but to be absolutely clear, my final question on this subject:

My wheels' rim width and diameter are rated as follows in the car owners' docs: 7.5Jx17. So I can still go for a staggered set up with 245/45x18 front and 275/40x18 rear tyres?

Only if you buy new rims. You can't fit 18" tyres to 17" rims.
The 17 or 18 refers to the diameter of the hole in the middle of the tyre.
The rim must also be the correct width for the tyre. You can't fit 275 wide (width in mm) tyres to a 7.5" wide rim nor should you fit 225 tyres to a 9" wide rim.
Matching tyre size to rim is very important for safety and tyre longevity.

True but the tyre in question will have an acceptable rim width listed that it will work with so there is some leeway on section width and height. IIRC according to the tyre spec sheets there's a good 1/2" either way or more sometimes, so the tyres will stretch a little in width and stay within the manufacturers spec.
I fitted some 18X8j ET31 amg monoblocks to my w202 but found the fronts would sometimes rub the front arches. This was with 225/40/18 tyres as per alloywheels direct table which said they would fit. Turns out only the C36 and C43 AMG ever had 18s from factory and the front wheel arches were rolled more to accommodate.
I have just fitted some 215/40/18s on the front and the rubbing is gone. I could even have gone with a 205/45/18 and it would have still been within the spec of the tyre but borderline and zero rim protection.
The only issue is the load index now. The car should have 91 rated tyres and now it has 89 with the 215s. Even so, they can cope with 580kg each whereas the 91s can cope with 630. Gross weight of the car is 2000kg so the 215 XL tyres on there now are still more than up to the job but you have to clear it with your insurance company if you deviate from the official tyre spec listed by the wheel manufacturer. I have a multi car policy with RH insurance and they weren't worried about the slightly lower load rating at all.

After reading your posts on the other forum its clear you do not have 17" rims.
You have 18" rims and should fit 245x45xR18 tyres on the front and 275x40xR18 tyres on the rear. Nothing else!

The mention of 17" rims being in the car owners documents just confuses a straightforward question and answer.

Hi all I've just picked up a 2010 c220 cdi with 16" wheels and am looking to swap for a 17" set from a later w205 model the ad says they will be OK, the fronts will go from 7J16ET43 to 7J17ET48.5
and the rears from 7.5J16ET53 to 8J17ET54
I think they'll be OK but would like confirmation before buying thanks.

Standard 17" wheels on a W204 are:

Front Wheels: 7.5Jx17 ET47 fitted with 225/45R17 94Y XL
Rear Wheels: 8.5Jx17 ET58 fitted with 245/40R17 95Y XL

so the ones you are looking at are narrower:

The front will give you 5mm more inner clearance and sit 7mm further in than the OEM fit
The rear will give you 10mm more inner clearance and sit 5mm further in than the OEM fit

The tyres stated above will fit on the rims no problem, it should all fit

Many thanks for that, I'll make the guy an offer. These are what I have and I'm looking to replace them with.

Yeah, after some digging I did find they were just that little bit different and possibly just enough that they wouldn’t work, thanks for the confirmation though Jon

Entering the minefield of bigger wheels and tyres.......

1994 S124 320 TE fitted with standard 8 hole alloys 205/65x15 tyres. Not sure of rim width or offset but the wheelchecker link mentioned on here shows that tyre size on 15" wheel as being 6.5" width with an ET of 44,48 or 49??? The wheels are refurbished but have crappy Chinese tyres fitted so just using as an opportunity to see if any different wheels out there.

I am looking out for either period style BBS multispokes or MB monoblocks. Was thinking 17" rim with 215/50 x17 or 225/45x17 or possibly 235/45x17 and some website I was on said best/recommended rim widths would be 7", 7.5" or 8" rim widths respectively for those tyre sizes.

Looking on 'willtheyfit' website and I am confused as they have the standard set up as being 672.9mm diameter whereas I got it to 647.5mm (15" wheel = 381mm plus 205x0.65, twice = 133.25mm wall height, therefore 381+113.25+113.25=647.5mm) and the tyre sizes I am looking for on 17" rims ranged from 634mm to 647mm.

Probably just me but that site doesn't actually say if they fit or not, just gives +/- dimensions on various areas but the overlay picture seems to give a good indication of how similar the old and new are - I actually tried putting huge 21" wheels in to see what it would say and just the same sets of +/- numbers displayed.

I think I will be OK in my preferred sizes but would be nice to know actual ET of current wheel and what sizes would fit around my working numbers. I'd go for 16" if 'right wheels' came up (one of the compromises of likely 2nd hand/refurbed wheels but am thinking 18" will probably mean too low a profile tyre impacting more on ride comfort. I would go 'oversize' on the diameter if I knew they fitted and meant I got a higher profile more in the 55-65 profile range for comfort so would be wider and taller.

If speedo is anything like my convertible was, bigger diameter may actually make the speedo more accurate as the convertible under-read by 6-7mph at 70mph against sat nav speedo.

Any advice comments or a specific "this size will fit with this ET" appreciated

 

[JBell]

Usually it would be a 8x17" ET35 wheel fitted with 225/45 R17 tyres

7.5 x 17" ET35 will also work with that size tyre

Hello,

New here and a complete Noob when it comes to cars so sorry if any of this sounds stupid (please be nice).

I have a E class 220d Cabriolet 2020 with 20" wheels. As seems to be common I've had 4 fractured rims in the last 3 years. I was looking to change the wheels to smaller alloys bigger tyres/more rubber to try prevent this going forward. My questions are:

My current wheels are staggered, do I have to replace them with staggered wheels?
Would 17" alloys fit or be too small? I think I read somewhere 18" is the smallest you can go. Any suggestion on alloys/tyres is appreciated, I just dont want to spend money then find they dont fit.

Many thanks

Hello and welcome,

Have a look in your fuel filler owners manual - the smallest diameter wheels will be listed there - 17"'s might not fit over your calipers unfortunately - I had 17" rims on my W213 E220d with 235 width tyres all around without issue - standard brakes though

Thanks for the response. So looking at the sticker I should be good with 4 x 17s? Or should I go with the staggered 18s as I currently have staggered?

225 55 R17 will give you much more comfort and better economy

Hi all, I didn’t really want my first post to be a dreaded wheel fitment question, but it is what it is, I recently bought a C250d S205, with the 18 inch AMG line wheels, from what I have gathered I have staggered fitment, 7.5J ET44 at the front and 8.5J ET 49 at the back; please, someone correct me if I’m wrong. Now I want to put on a new set of winter wheels the set that I have seen, there are a square set up with a ET Fitment of 38, tyres will be 245/45/17.
from what I gathered, these should fit giving enough clearance to the front callipers, but I understand they will stick out slightly. Does anybody have the knowledge to tell me if the wheels will stick out causing rubbing issues on the arches?
Thanks in advance

The standard wheels are

7.5Jx18 ET44 fitted with 225/45R18 95Y XL
8.5Jx18 ET49 fitted with 245/40R18 97Y XL

17" standard "Square" set up

7Jx17 ET48.5 fitted with 225/50R17 98V

This will sit 10mm further in the arch than the OEM wheels so you can go down to 7x17" ET35 - 38 wheels all round.

The other option is to just put a set of winter tyres on your existing wheels
