I mean, I wince every single time I turn my compressor on because im convinced its going to explode and kill me into pieces (never google ‘air compressor accident’), but, its rated up to 120psi..
I don’t know what the max pressure for your tyres is, but, it’s not 100psi. Jumbo Jims are 30 I think. And tyres coming off rims is pretty violent, I thought I’d broken my hand last time it happened (the wheel ended up flying across the room)…
When trying to seat a tyre onto the rim isn’t it standard to go for highest possible air flow available (for as long as possible, until seated)?
Tested the tyre this morning and it’s lost about half its pressure over night.
Any tips on sealing these Dune rims up good and proper?
I had electric tape over the whole bed of the rim, worked well. But ime it’s pretty common for tubeless tyres to go down until you’ve given them a proper ride. A short thrash helps but it takes time to really settle them and spread the sealant around.
