I don't wish to step on your toes nitros, I would just like to add a link which if scrolled down to the picture of the tyre I think is a very good visual example of cords/ply exposed en.wikipedia.org/wiki/Tire#cite_note-17Dave |

so where the fibre cord is visible if you see a tyre that is very nearly down to this the layer of rubber is usually darker in colour i was wanting to know if this is classed as ply the other tester at work says it is but i,m not so sure cheers for your help guys

I WAS TRYING TO GET GOOD EXAMPLE OF REAL TYRE SHOWING WHAT YOUR ASKING, FROM WHAT YOU ARE SAYING IT SOUNDS LIKE THE TYRE HAS WORN THAT FAR DOWN TO THE BRACING PLY LAYER (FABRIC BELT)WHICH LIES JUST BENEATH THE TREAD, IF YOU STUDY THE PHOTOS IN THE LINKS PROVIDED BY THE 2 DAVES THESE SHOW THE DIFFERENT LAYERS. ALSO TAKEN INTO ACCOUNT THE TREAD BLOCK WEARS DOWN IT WILL EVENTUALLY REVEAL A THIN LAYER CALLED A BREAKER PLY WHICH MAY BE A DIFFERENT SHADE WHEN EXPOSED.(FABRIC).I WOULD SAY THIS WOULD BE RFR AS ITS EXPOSED SOME LAYERS HAVE ALREADY WORN AWAY IF THE STEEL CORDS ARE EXPOSED BUT MAY NOT BE OBVIOUS |

Some tyres have what Goodyear/dunlop refer to as a "blanket layer" below the tread. Its function is to stop the cords contacting the treat which can actually wear the underside of the tread rubber as the tyre comes under load. This layer is generally darker than tread rubber and can be felt to be different if picked at with a fingernail. it is all "rubber/synthetic compound" and does not contain cords os fibres
According to the man who taught me on a course at Dunlop, he doesn't think the exposure of a blanket layer constitutes an MOT failure in it own right, but its bloody obvious the tyre is boogered!
