Not the happiest I’ve ever been, car failed it’s MOT for 3 tyres - see above!

Anyway, the back left tyre had worn on the inside edge, and they believe it’s not just alignment, something is wrong with the suspension. What are the common faults to cause this please? Expensive to fix?

X3 tyres is disappointing, moreso as you’ll need to replace complete set (x4) made all the worse as there appears plenty of tread... I blame the tradesmen that leave screws rolling around they’re van....

Is it possible you’ve misinterpreted the conversion
All Bmws wear the inside of the tyres, (infact rear inside, front outside) it’s the way they are set up as Rwd bias
I’m on my umpteenth Bmw and all have similar traits, it’s why they handle so well...

Top two look to have lots of minor cracking between the treads so a good time to get them changed before they become a problem. :) Just after Christmas isn't the best time to get a bill for 4 though !

The top two photos show cracking in the grooves - usually associated with older tyres that have stood for a while (as with caravans) . What is the DOT code that shows the date (week and year) of manufacture. Frequently heard advice is not to use tyres more than 5 years old, though some advice says 7. My caravan insurance company will not pay out if tyres are more than 5 years old, irrespective of the amount of tread on them!

Odd one this. My X6 passed its MOT in October despite having a nail in a tyre - which was classified as a ‘Repairable’ advisory. I would have expected a non-leaking hole to be far less concerning than a tyre with a nail in it!

What is the wording on the fail.
I would think it's the cracking and not the hole well that is what i would fail on when i was testing.
The rules have changed a lot but i will check when i go in the garage on Saturday morning for my cuppa.

I’d be very interested to hear more as I feel this was extremely harsh and if you looked hard enough, you’d find similar ‘damage’ to virtually every tyre on the road today.

Thankfully I had a set of Winter wheels at home which I had them swap over for me to pass the MOT.

Hi,
This from the current MOT guidelines testing stations have to follow:

You can use a blunt instrument to open a cut in the tyre to check for exposed ply or cord as long as you don't cause further damage.
When assessing cuts in a tyre, it is permissible to check whether a cut is deep enough to reach the play or cord by using a blunt instrument to open the cut taking care not to cause further damage.
The following criteria should be used when assessing a cut in a tyre:
any ply or cord that can be seen without touching the tyre – fail
if by folding back rubber or opening a cut with a blunt instrument, so as not to cause further damage, exposed ply or cord can be seen irrespective of the size of the cut – fail
if a cut which is more than 25mm or 10% of the section width whichever is the greater, is opened with a blunt instrument and cords can be felt but not seen – fail
Before failing a cut, you must make sure it's the cords that you can feel not a foreign object. If you're not sure, then you should pass and advise.
When assessing lumps or bulges in a radial ply tyre, care should be taken to distinguish between normal undulations in the carcass, resulting from manufacturing, and lumps or bulges caused by structural deterioration.

So as already said, what does the wording on the certificate say? Testers now have to categorise faults as Dangerous, Major or minor. Dangerous is an automatic fail!

Hope this helps,

Graeme

Thank you Graeme, most helpful.

I’ll check again tonight but I certainly couldn’t see any cord through the cuts.

With regards the certificate, I just have the pass, they told me it had failed on 3 tyres over the phone and did I want to have them replaced by them, £258 per front tyre and £319 for the rear.

I explained I had another set of alloys and would bring them up to swap over. Truth be known, I knew there was an awful lot of tread left so did question the decision and wanted to see the failed tyres.

Just an update following the comment they could be old tyres and that’s why they could be cracking, just checked and the oldest tyre was manufactured week 25 2016.

Rears both have 5mm tread, front have 6-6-5mm tread.

Seeing so much deterioration on two and half year old tyres is not good!
