Potted history of my road tubeless tyre adventures:
DT Swiss R411 rims with Schwalbe Pro 1, the wheel builder set them up for me.
Rear punctured on first ride and would not seal, ended up riding it with a tube (for about a year) until the tyre became deformed from being taken off the rim too many times as it suffered further punctures.
Replaced with a Hutchinson Padrone, that punctured on the first weekend, I tried to glue it but only managed to create a slow puncture and the sidewall of the tyre became porous due to riding it at low pressure. Put a tube in it and carried on fine (no further punctures) until I broke a spoke on the rear wheel so had to take it off anyway (about 9 months later).
By this time the Pro-1 on the front wheel had about 5,000km on it and was weeping sealant but still rode fine and held air well enough.
I binned both tyres and fitted IRC X Guards. They were tight to get on, I needed to use the IRC tyre levers. Would not quite inflate with a track pump but a CO2 cartridge got them seated and they remained seated when i deflated to add sealant through the valve stem. Went out for a quick ride and they feel good. They seem quite narrow for 25c.
If I end up with a tube in the back wheel, I'm going back to regular tyres.
