Clk 200, urgently need advice on tyre size

[davinaharry]

Hi everyone, I am new

I have CLK kompressor Cabriolet / no manual. I understand Mercedes requires the Rear tyres wider than the front.
I need front tyres

225/45/R17/W94

I want Uniroyal Rainsport but they only have the size with the speed index Y or V
I believe also they should all be the same W and should you do mix, the front has to be lesser than the back, so it will be V
As I do not have the manual to see what the Mercedes requirements are...I was hoping someone might be able to advice me, if V is an ok substitute for W ?
...

So I found an alternative ;

Goodyear EfficientGrip Performance 2 but they only have W91 and mine are W94

please can someone tell me what size is recommended. I tried to look inside the door and petrol cap and there are no tyre and wheel size printed anywhere. So I’m buying blind really.

thank you in advance

I just found this online, I guess the above is what I should have but currently on mine are as follow.

Front 225/45/R17 94W
Rear. 245/40/R17 95W

Would the Goodyear EfficientGrip Performance 2 (225/45 R17 91W) be compatible and safe, and would insurance approve?

Thank you again

V,W,Y or Z would all be fine as they are all above the maximum speed the vehicle is capable of.
91/94 are the tyre load ratings. If you have 94 in the spec for your car you should only use 94 or higher.
What does it say inside your fuel filler flap?

The passenger tyre blown whilst on the motorway and the Rac left me waiting for THREE full hours on the hard shoulder.
It turned out, I need wheels aligned. It makes a rumbling noise at around 70mph and the steering wheel pulls the the left. I think this has damaged both my tyres. I only purchased the car just before lockdown and it didn’t come with a manual.
I did tell the car dealer about the noise but they were not interested.

I need good grip on wet weather and deals well with aquaplaning as I tend to do motorway driving, journey lasting 1hr and it is always raining

Thank you LostKiwi I shall go and check and take a picture later. But I couldn’t see any tyre measurement last time I looked

 

[davinaharry]

I really want the
Goodyear EfficientGrip Performance 2 (225/45 R17 91W) I shall see if they have them in 94W

 

[davinaharry]

The problem is, whoever owned the car before me has put 94W
Which I believe is incorrect. It should be 91W

what shall I do ‍

Welcome
Firstly your staggered set up is fine. The 91 rated tyres I believe are the original load, higher load ratings will also be fine (some previous owner has gone 94 & 95, no issues at all there). W and above speed ratings will work and have no insurance implications.
However I'd stay with higher load ratings and speed ratings if you are keeping the rears at 95W if at all possible just to keep the car balanced (I'm a bit OCD though).
the Rainsport 5 you mentioned will work fine , they are Y rated with a 94 load

yes they do is the answer if you really want them.....

The good news, I just found...
Goodyear EfficientGrip Performance 2 comes in both sizes

225/45 R17 91W
225/45 R17 94W

so I just nee to know which should I order.
The tyre websites states 91
But I have 94 on the back already.
But if they have to be matching... I am going against the Mercedes recommendation

I’m so sorry to be a pain

our posts crossed! see my earlier replies, I'd go with the 94W

 

[davinaharry]

Would you believe, whoever put tyres on the front (which one is part worn due to the tracking out and the other is burst and in the boot)
They had put XL yet the rear are not

Welcome to the forum!
On my E class I have Y rated tyres on mine which should be perfect for you’re car too I think Y is 186mph?
Also just one quick thing if you’re stuck between choosing tyres I went for Pirelli P7 citurato and 15k miles later on the fronts I’m still on 6mm tread!

I’ve got some of them in the E class , all 2008-2009 , no cracking at all and I can’t wear them out , still got 5mm on them .
Yes I know this is their last year (although I said that last year )

Very quiet and comfortable as well

I have the Goodyear efficiency grip on my CLK 230 and am on my second set. I love them and they are well rated for all key aspects; wet, noise etc. Once you sort your sizes through the forum I would highly recommend the goodyear

Welcome had two CLK's the wider rear tyres are an option, you can have 225/45/17 all around.
You can also go down to 205/55/16 which I had on my winter wheels.
Rainsports also get my vote.

As above. Check your wheels and only fit staggered tyres if you have wider rear rims than front.
