Letter from DVSA

So once again our inadequate tyre laws win again. when i see some of the tyres we are supposed to pass it makes me cringe. and why should we be passing part worn tyres that have be imported after most cases beeing unfit for continental use.we see lots of winter tyres fitted second hand yet we cant fail them .

didn't your initial post state that the cords were exposed?if that aint the case then they've got you bang to rights.those wear bars in the tread are generally about 1.8mm not 1.6,the test is whether the centre 3/4 is at or above the limit,have just had to advise one myself that has inner edges worn to internal structure,you know,when you see a few different layers of rubber.in my estimation has about 2 trips round the block before the cords come thru.still had to pass it.the worrying part is that for minor crap like this they would just send you on a course generally,given the  cpd sylabbus its gonna be at least a year bfore you have to bone up on tyres and refresher courses are now gone,disciplinary is about all they got left,let us know how it goes,this is the first ive seen under the new system.

Remember this?

think you might get a different opinion from the ministry,anyone out there can confirm this?you have to prove that those changes in colour are a ply,pretty much impossible in situ,unless ypu can see ply as in fabric or cords p+a

Ply isn't cords. ply can be fabric reinforced and also not. It is just a different layer the same as plywood, go through one layer/ply and expose the layer/ply underneath.

The important wording is "ply or cords". If they would have meant only cords they would have only written cords. Like so many thngs MOT related it depends on who you talk to - my VE's in both London and Derbyshire both say a difference in colour means it's a different layer (or ply) from the outer tread and therefore is a fail.

Brake hoses only fail when showing cords, as is demonstrated by the wording...



It's another case where if it had happened to me I'd be fighting it all the way. If they were to remove the words "or ply" from the RfR then fair enough but until then.....

I always thought ply was the fabric type part and cords the steel wires, think we all need more info from DVSA

yup,how many times have I seen 3plys rayon,1 ply steel or similar on the sidewalls of tyres

as it says in the manual, tyres may be devoid of tread on the edges, i.e. bald.its the central 3/4 of tread that matters, or the tread with wear indicators.
