Thanks, AG Falco

I bought the car new, it came with the same Continental tyres as I have now (I suppose about 8 tyres have been changed over the past 7 years and nearly 70,000 miles through punctures and wear).

... are we saying that Skoda do not fit Continental 225/49R18 as OE? See above, I bought the car new from a Skoda dealer so I’m the first owner, that is what it came with.

No, they are fitted to other cars. https://www.tyreleader.co.uk/tyres-advices/car-tyres-markings

No.

They would/could have come with 225 40 18 Continental tyres.

 

But I doubt the car came with MO marked tyres from new. ( MO means they are Mercedes Original approved tyres )

I have never seen this. More likely the MO tyres were fitted at a later time/date.

 

Thanks, AG Falco

That size is not approved for his car; look at the photo he posted.

Hi,

Thank you for that, but it seems (to me) unlikely that the car should have come with 225/45R18 tyres when the sticker inside the fuel flap lists 225/40R18 (see the photo below). I’ve owned the car from new, it has had a few new tyres over the past 7 years, but I have always had them replaced with the original size.
I think you must be mistaken about the 225/45R18 tyres - I have no idea about the MO bit, the tyres would have been supplied by a reputable garage either to replace a worn out one or a puncture. Does it make any difference?

Ah, that was just my fat fingers typing on an iPad, it should say 225/40R18.

Do we agree that is the right size for the car?

I’m not sure I understand the ‘MO’ issue, are you saying my motor car could not have come with Continental tyres (in that case you would be mistaken - I am the only owner)? What is the significance of the ‘MO’ marking (apart from being approved by MB), are you saying they are unsuitable for my motor car?

I’m a bit confused.

alan

Yes size is right size but MO marked tyres are not OE for a Skoda.

 

If the MO tyres are good enough for a MB then they are good enough for a Skoda.

Thank you for clarifying that, I’m relieved to know my car has the correct tyres.

I’m slightly confused as to why the MO marking was in any way significant, this is a 7 year old, 70,000 mile car, so the original Continental 225/40R18 tyre probably didn’t have a MO marking (but that was probably 2 tyres ago). Whenever it was changed I’d have just told the garage to fit the same tyre, I have no idea why it would have supplied one marked MO, but if it doesn’t make any difference then why should I be in any way concerned?

 

I’ll check the other 3 tyres tomorrow to see if they are also marked MO (I suspect there will be at least one more as I normally buy them in pairs, unless it has been to fix a puncture).

Thank you for that, would I be right in thinking the MO marking is of no significance whatsoever on this 7 year old, 70,000 mile car?

Alan

It would have got the MO marked ones because that was what they had in or got delivered for fitting to your car.

No problem and no issue, and no different if they had been AO marked.

 

If you go to the likes of BlackCircles and go by tyre size and not the car details they ask what manufacturer the car is.

 

Go to https://www.camskill.co.uk

  You will see the tyres showing the car manufacturers for the same sizes.

Some people want exactly the same tyres that the car came with / exactly the same tyres all round.

 

In certain cases having the correct size but not the correct manufacture marking can do damage to the car.

We had one car where we advised them NOT to fit the tyres they had ordered.

This caused a £5000.00 repair to be needed on the car. 

 

This is not the case with your car.

Thank you both for that reassurance chaps, you had me worried that there was something wrong for a while. I had never heard of the car manufacturer’s marking previously (I don’t know much about car tyres), I’d have just told the garage to get the same manufacturer and size.

Alan

Thank you, I have learned something new about car tyres this eve :-)

Here are "Mercedes OE" tyres listed on Camskill in the 225/40R18 size. You will see your Continental SportContact 5 tyre on this list.

However, notice the Michelin CrossClimate+ tyre on this list of all-season tyres:

You would have much better winter performance on all-season tyres than summer tyres below about 10 degrees Centigrade. The performance drops off quickly below 10 degrees Centigrade especially in the wet. You don't need snow/ice to notice a big improvement on all-season tyres in the winter compared to summer tyres...just cold weather.

Thank you for that, my knowledge of car tyres is increasing exponentially!

 

I understand your point about all-season tyres, but I have dedicated winter tyres and summer tyres, surely that is a better solution (and saves my shiny alloy wheels from the winter weather)?
Alan

Yes. Not least because you (or someone on your behalf) will be taking wheels off twice a year which allows easy inspection of wheels/tyres/brakes/suspension/CV boots etc. This is likely to benefit you in spotting problems earlier than might otherwise happen.

The tyres will also last longer, roughly twice as long.

Thank you for that.

I change the wheels myself and give them a good clean up before storing away securely in my motorbike shed for the winter/summer. I agree it is always a good idea to keep an eye on mechanical parts.

I did spend quite a long time researching your two tyre types.  The EU labels give the Contis a fuel efficiency rating of 'E' but the Yokohamas are worse at 'F'.  In theory,they would decrease your mpg by about 1.5%.  Yokohama V905 rolling resistance is 9.43 kg/tonne  (not quite the same as your V902A) I'm still looking for the Conti figure.  Both tyres have a noise rating of 72dB.

Thank you for that. It is a little strange, subjectively I'd say the Yokohama tyres are significantly quieter than the Continentals, and from a fairly scientific comparison (well, scientific in the sense of measured by the same means, on a known route, with about the same load and conditions with me driving about the same way) the fuel consumption is rather better.

 

I'm rather dubious about the efficacy of low profile tyres (I mean 40% in this case) on most road cars. My previous Superb (much the same car, but 3 years older (so 2010) and one step down from the Elegance trim) came with 55% aspect ratio tyres on alloy wheels which were quieter. I suspect the 40% ratio tyres are for marketing purposes only and add nothing much to performance or economy whilst being much more prone to punctures and damage. If I was buying a new Superb again I'd probably opt for higher profile tyres (even if that meant downgrading a bit).

... I checked the summer tyres (in storage) today, they are all 'MO' marked - I'm guessing they are just what is easily available to replace Continental SportContact 225/40R18.
