Ok road tubeless experts, I've been running schwalbe pro ones Stan's alpha 340 rims for years with no problem.
I however have nothing but issues with Vittoria corsa speeds. One tire will air up and hold pressure for about a week before it goes flat the second fits looser, has leaked sealant from "sweating" through the sidewall, but also bubbles through the rim tire interface and loses pressure entirely within a day. Am I doing something wrong or is my second Vittoria tire defective?
My conclusion is that any time air escapes between the bead and the rim there's a problem with the tire when used on tubeless specific rims.
I had a similar issue with a Schwalbe Pro One, the tyre 'seeped air' this was hardly noticeable at first, I thought I was leaking air around the bead, reseated, checked for debris etc.... it wasn't until I wiped a wet cloth along the sidewall, only to see the water 'bubble' with air.
I think this must have been one of the earlier batches of production tyres from Schwable as I remember there were very little stock available at the time.. it was clearly a defect. I can't remember the exact details but I was told by someone at Schwalbe that this was 'normal' and is why they state their tyres need sealant, however I ended up sending it back to shop and getting it replaced in the end. Only one of the eight odd tyres I've been though have done this.
I'd suspect you'll need to put a 'load' of sealant in them, wiggle it about a bit and make your own 'seal' within the tyre to be effective. Which IMO is a bit rubbish..(or maybe it's not rubbish, maybe it's an effective way of getting a lighter casing and tyre - it's supposed to be about 205grams right?) Either way it's another example of the tubeless 'industry' still working itself out.
