Nobby Nic UST, any experience?
fitted a pair of these on Friday, they grip fantastically, roll beautifully but hold air like a wet sock.
noticed foam forming on the tyre when i used muc off last night so they are leaking through the carcass
any body used these and had to put latex in them?Posted 9 years agoorangeMember
sounds odd as UST tyres have a butyl lining on the inside of the tyre to stop such air leakage
are they quite old and have worn sideways in any way?
do they have this UST logo on them?
i use NN UST tyres and ALWAYS use latex sealant with my UST and tubeless ready tyres – what else is going to keep the air in all the holes the thorns round here make?Posted 9 years agoFarticusSubscriber
NN USTs hold air fine, but they’re very delicate IME. I’ve trashed 3 with punctures – by the time I’d stopped, the tyres were flat and had torn small holes just above the bead. All had sealant in them which sealed other tyres (incl. the much more robust Schwalbe Alberts), but strangely not the NNs.Posted 9 years ago
My rear NN UST leaked a bit but I put some sealant in and it stopped, obviously. Never had any other problems whatsoever. I did have trouble getting them to seat once after swapping tyres. Latex had got into the groove for the bead and was preventing a perfect seal, cleaned the grooves out and problem gone.Posted 9 years ago
just cleaned the bike and I reckon my gorse theory is correct. Both tyres seem to have loads of pinprick punctures, more on the rear than the front. I guess they are a lot more prone to this form of punctures than tyres and tubes. Latex it is then 🙂
IT’S FOAM FROM MUCOFF AND AIR LEAKING BEFORE YOU START
