Did something really really stupid
I didn't get any weeping on my 26er tubeless setup. Same tyres in a 29er and it's like something from Stigmata.Weeping through the sidewalls is almost normal I think... All my maxxis have done it to varying degrees from new, and the Michelin wild enduro sweat massively.
Never come across anything not sealing at the bead though - pull it off and make sure you’ve not got any old sealant goobers on the bead messing up the seal?
Strangely they seem to hold pressure better, although perhaps that's just from having a larger volume of air to begin with.
