they will fail the MOT like that already. Sorry, but they need to be replaced. There is another recent thread on the same subject, same problem.

Thanks (I did search first..) I had a feeling that would be the reply!
ahh just found it...here thx!

That's the tread delaminating.... when they make tyres they make the body with the reinforcements in one bit and the tread section as another.... then stuff them together in a large heated tool which forms the patterns/tread, cures the rubber and bonds it all together.
You have the thicker tread bit coming off.
MOT fail as they stand if all in that condition.
And worth 3 points per tyre if Old Bill pulls you over.
Sorry.

LOL, I'll be OK only 6 points then... I'll get them changed asap thanks.

2 tyres changed, not Michelins but it's interesting that if you compress the tread rubber on the new tyres it feels a lot softer than the remaining Michelins, so either it really is a lot softer or the remaining Michelins have dried out. (tempted to go back to check against a brand new Michelin...LOL..)
I noticed after they were fitted that the load rating on the Michelins is 88V and the new tyres are 84V, but the tyre shop said they were a direct replacement...should I be concerned?

@twodogs thanks, will do...From memory the date codes were mid to late 2020, I'll check
Michelins 195 50 16 88V new much cheaper tyres 195 50 16 84V. (load factor 88=560kg 84 = 500kg)
I'm never going to carry that sort of weight but my concern after what I read was whether an insurance company would refuse a claim - if for example you had an accident caused by a blowout.

Good question, I never thought to check!
Update, nothing in the handbook but the sticker on the door with the tyre pressures says 88V. However if I put my reg number into various tyre sites some do specify 84V as a replacement.
I'm not at all concerned about the performance of the tyres and I'll bet this happens with loads of tyre changes, but still....
