Tyres disintergrating with mousse fitted

We are having a problem with rear tyres coming apart, the nylon internal cord is detaching from tyre carcase when run with a mousse. I hear this is not uncommon, due to the lower pressure in tyre with the mousse

Are the tyres still OK to use, despite obvious signs of deterioration ?

I have found that too when using Tubliss at low pressures. It flexes the tyre wall beyond the ability of the rubber compound to hold the nylon threads. I always find that one side of the tyre seems to have threads hanging out like a spiderweb, the other is normal. As yet, I havent had this cause a tyre to fail with splits or tears, I have always worn the tread out before they have failed
Full Throttle. It either solves your problem, or ends the suspense

had this happen with pirellis only. and only discovered after removing the tyre from being worn. so no measurable affect on the tube/tubliss/mousse

Yes, unfortunately it was Pirelli midsoft, a tyre we use all the time . Might just keep them for summer/non-competitive use

One thing to watch out for with Pirelli's too is that they have a skinnier bead than Michelins for example, I don't know about the other brands.

So compared to Michelin at least your rim lock isn't going to be as effective, or you may want a wider rim lock.

No issues with tyres falling apart on mouses, but have had mouses destroyed using Mitchy Starcross tyres.

No issues with the old S12s, Metzler or Dunlop.

Have done a few tyres with collapsed sideways in conjunction with tubliss

No issues, but I imagine it would be a better situation with mousses with rim further from ground.
It pumps one way and then it pumps the other...
you have to know what you're doing with these machines and wear gloves
