    I'm looking to buy a new set of tyres off camskill I was going to go for PS3's but I notice they do CONTINENTAL SPORT CONTACT 2 225/40R18 92Y XL (AO) FR TL (Audi) as well as ONTINENTAL SPORT CONTACT 5's.

    What I wanted to know is whats the difference between the normal contact 2's and the AO Audi ones and if the Contact 5's would be a better choice?

    SC2's are not meant to be that good, SC5's on the other hand are meant to be the nuts! As for the AO i have no clue.

    stands for Audi only, I have SC3's which are very good and the quietest tyre I've owned, all mine have MO on them (Mercedes only) not sure whether there is any difference between them all

    Its to do with the tyre manufacturers producing tyres marked for the brands they fit on as OEM tyres, they do massive deals with car manufacturers to get their tyres on cars and when the deals are agreed they will produce x amount of tyres marked with the manufacturers designation. Most will go to the manufacturer but part of the deal is x amount will made available to the public to buy as replacements. Continental say that the first three sets of tyres on alot of cars will be what they came with from the factory as the owner will want to keep it original. After that the car starts getting to an age where price becomes more of an issue for the tyre purchaser and depending on the owner (if they are even the original buyer at that point) the tyre brand and model starts to become a non issue over price.

    Car manufacturers have lots of different idents for OEM tyres, AO is Audi Option, MO Mercedes Option, a Star on the side wall is BMW, N0 N1 and N2 is Porsche.

    The tyres are the same the only difference is molds they come from though have the OEM designation, i.e. the SC3 with AO, MO or the star will all be built with the same construction and rubber just the mold has the emblem on it.

    My PS2's are all MO's. Its the only PS2's I could get. No difference that I can notice.

    Dandle has it spot on. It's just a marketing / sales ploy. Someone called one of the tyre makers about MO spec tyres and they admitted straight away that 99.9% of OEM spec tyres are identical to none OEM. They said that on ultra high end cars they may make a slight change to the compound (e.g. on a SL63 AMG )

    The code also means that there will be ever so slight design change on the tyre to suit the manufacturer. Mostly the design change is the side wall design. For example Honda S2000's use Bridgestone RE050 however they have to be the MZ coded ones as the side wall is much stiffer. It's very noticeable when you drive an S2000 with none MZ tyres.

    Agree 10/10 but 'mould' please not 'mold'! :yes:

    I can't comment on Bridgestone but Contis are certainly the same no slight differences at all. If they make a tyre specifically for the model it gets renamed like Sport Contact M3.

    Good spot :)

    Porsche-spec N-rated tyres are definiely NOT the same as non-n-rated tyres off the same type, the sidewalls on them are very stiff and sometimes the difference is more than that, different rim protector/sidewall.

    I have conti sport contact 5s and i have to say they are much grippier in the wet and dry than my previous PS3s also a bit quieter too, so looks like the reviews on them are bang on

    First of all AO is the Audi Tyre marking. This means Audi worked with the tyre manufacturer to develop this tyres, and it has been designed with their vehicles in mind.

    The Continental Sport Contact 5 is the newer version of the Continental Sport Contact 2. It would be best to take advantage of the newest most recent technology.

    It doesn't mean Audi worked with the tyre manufacturer at all. It means they both have done a deal for the tyre manufacturer to supply Audi OEM tyres.

    Bridgestones RE05A's good but noisy I find. Michelin's are the way to go I think. Very good in the wet I found.

    ^^^^^ This, having been shown the Michelin tyres and the differences I whole heartedly agree, They are NOT the same.

    Sorry to resurrect but just wondering - if MO and AO are the same as non oem, why do they have different ratings?

    here is MO v normal
    Mobile Photobucket

    AO shows 'F' for fuel and 'B' for wet weather.

    Ok this basis it seems normal would be the better buy but not sure

    The Porsche N0,N1,N2 tyres are very different to the normal versions - different compounds, different construction and hence different characteristics.

    How different Audi and Mercedes 'specific' items are is debatable, but given the different ratings then I'd suspect the compund is different. Externally without the AO/MO markings you'll not visually see anything - perhaps the treadwear rating is different, but tread designa nd general sidewall design will be identical.

    At least with the EU tyre ratings, you can see what the differences are, rather than just plumping for the cheapest version of a specific tyre because its the best in test, or recommended. That of course assumes all similar tyres were tested on the same rims on the same car (wheel weight will affect economy, and my Golf Mk 6 17" alloys were stoooopidly heavy).

    Hi just wanted to share my own experinece of the conti sport contact 5 and the conti sport contact5 AO

    I bought my seat leon ex demo only had 3k miles on it with the 5 ao's on from new. I work at seat and have checked many different cars all the same.

    Anyway back to the tyres.
    The 5 ao's as standard lasted 10k miles no problem. I then put the 5's on not knowing that they were different. 2500 miles later and to my total disgust they were at 2mm. Shock. 6 weeks they lasted. I couldnt figure it out i drive hard and always have but 7500 miles less really was a huge shock. I have since got the ao's again and 6000 miles in still driving hard and still have tread left on them. So i will say they are differend compounds/grades of rubber and hopefully i can get them for years to come. Fuel rating is a c and grip rating in wet is b. on the non ao's the fuel rating is c and grip is a. Please avoid these if possible unless ur mental and have a bank balance bigger than most.

    Hi all

    Bit late to the party here but was reading the forum after looking for some new tyres. If they are so identical then why the different ratings? On the Sport Contact 5's we have:

    MO: B for grip and C for economy
    AO: B for grip and E for economy

    Surely they cant be identical then?
    Would I be better putting the 'mercedes only' tyres on my A3 then???? Makes no sense!

    Thoughts please. They're running thin!....

    I have bought 2 single tyres one ao and one mo the tread pattern is slightly diffrent! along with the feul rating. They are both going on my 2008 s3. I just need a decent reliable tyre continental aren't going to make big changes and still call them the same thing

    I would just like to point out that there most definately is a difference when it comes to Dunlop Max Sport RT that are marked MO, AO and the ones wit no marking. Not only do the MO have a bigger rim protector, when you fit anything other than MO on the Mercedes there is a problem with tyre wear on the inner shoulder to the extent that the tyre can fail catastrophically. ATM on a 2015 A45 AMG there is at least 1mm left over the centre 90% of the tyre but the inner shoulder is through to the canvas and then through to the wires in places, it actually looks like it is rubbing against something, but I think it is down to the construction as this is the 2nd pair of front tyres it is happening with (Original MO marked tyres still on rear with no problem) and tracking/suspension has been inspected with no faults

    Just use Uniroyal Rainsports. Possibly one of the best tyres out there, especially in rainy ol'd blightly..made by Continental as well.

    Go for the Rainsports, and save some pennies for modifications.
