I am sure the term run flat used by billy meant run under inflated or deflated rather than "Run Flat" by design.

I regularly encounter a similar situation during truck check, usually multi drop, where the nearside rear outer sidewall gets constantly scuffed against kerbs etc, gradually wearing away the sidewall. Often the shape and outline of the body cords can be clearly seen under the thinnest of thin layer of rubber, but without actual exposure of the cords, which would still pass a roadside inspection, with an advisory note.

I am sure billy will correct me if I my understanding of his posts is wrong.

the cords as they are covered in rubber are not "exposed" hence the Pass and Advise, exposed to me means "clearly seen in there RAW form" and not covered in a layer of however thin rubber.
Which also poses the question where you have an unscrupulous presenter who "paints" the exposed damage.

the tyre in question failed on lumps to sidewall, but have seen plenty with bad runflat damage that went out the door with a Dangerous pass and advise,


Previous to this, you said;

had old 206 in with a tyre where you could clearly make out cords all round the tyre to inner and outer walls BUT still coloured black from the rubber

Not sure where all this is leading, but the manual does not ask us to check the colour of the cords, it clearly states cords or ply exposed are a fail.

You said in your first post, "you could clearly make out cords all round the tyre to inner and outer walls". If you could "Clearly" make out they were cords, then there was no element of doubt, you should have failed the tyre(s) for ply or cords exposed surely.

Did the vehicle manufacturer fit as standard Run Flats on the 206 range?

Painting the damage is no different to coating brake pipes in grease or copperslip, or covering welded repairs in copious amounts of underseal.

If you cant see or prove the defect you have to pass & advise & move on.

Likewise I would need to see the tyre before making a decision.

It's worth bearing in mind that you may come across some situations for which there is no clear answer in the Manual. If you have studied the RfR's and still cannot make a clear decision then its a pass & advise

I believe I would fail it too but would have to see it for myself first to make an accurate decision.

If I can see cords without touching the material, for me its a fail. Reason for rejection 4.1D.1b. Any ply or cords exposed.

Ok, we have all seen tyres where the sidewalls show run flat damage BUT when is it a fail
had old 206 in with a tyre where you could clearly make out cords all round the tyre to inner and outer walls BUT still coloured black from the rubber . The cords were clearly visible but with a thin black rubber covering
I passed and strongly advised
What would the rest of you do !!!!!!!!!!!!!!!!
