In advance: Sorry for yet another tubeless thread, hopefully it'll just be a quick one.
1. I've heard that you can use non-UST tyres for tubeless, and that you don't have to use new tyres. With that in mind, can I use my 2 month old single ply high rollers with a Stans NoTubes kit? Or is it asking for trouble? The tyres are fine tread-wise and don't have any tears etc, although the sidewalls are a little bit marked in that criss-cross sort of way that occurs over time.
2. Secondly, is single ply a really bad idea? I don't particularly want to add weight to my bike going tubeless, which I almost certainly would do if I went for UST or Dual Ply maxxis. I was looking at some of the Schwalbe 'tubeless-ready' tyres like the Nobby Nic, any thoughts?
(Background: I want to try tubeless because I get on average a pinch every 2-3 rides and it really irritates me. I'm running 2.35 single ply high rollers on Stans flow rims, riding mostly in the peaks)
