Iv gone gorilla tape and its worked, well so far. Im not 100% sure about the valves so iv stuck some roof sealant under them to make a seal.
Iv pumped th up to 50psi and done a quick 5 min ride round the block. When i pumped them up some stans did ooze a little but nothing major.
Proper tubeless valves seem to just work…. I’ve used some cheap specialised ones before and the pressure seems to keep em where they are meant to be … I’d bet the ghetto ones would as well…
A bit of ooze is normal, I’ve had puddles from old tyres full of punctures and they all seal with a bit of shaking unless there is a huge tear … and even then a inner tube patch inside and superglue outside (in the actual tear) has worked….
50 psi… that would blow my kids tyres off his Stans Crest. I only know this because I did it! One hell of a bang! (and sealant all over the kitchen) .. worse I did it about 4am in the morning (working nights) and the OH came down “wtf happened” .. and I’m sheepishly trying to mop up sealant
So I think “so far” will be good.... the longer its in the better (within obvious limits)
