Just been into my local independent bike shop to pick up some stans tyre sealant.
neither of the two assistants had even heard of stans sealant, or indeed the brand “no tubes”!
once i had explained, and also asked for them to order me it it, as well as a dual ply minion with butyl insert, and I was informed that, amongst other things…
there is no point running dual ply downhill tyres to reduce pinch flats/dinged rims as all they do is protect against ripped side walls…
from the maxxis website….
An extra layer of butyl rubber wrapped around the bead of a Downhill tire that helps prevent pinch flats and protects the rim from hard hits.
So they are more expensive than the online supermarkets, which i dont mind if the service is good, but clearly not….
