Tubeless: what am I doing wrong?
I bought some Joes No Flats and fitted it to my front wheel with Nobby Nic EVOs with no problems. I then turn to the back wheel about a week later. Followed the same process and wheel goes up okay. However, there seems to be a number of leaks from the side wall where sealant comes out but they do not seem to be sealing properly. Hence the tyre is soft after a number of hours.
Do I need new/different sealant, a new tyre or an inner tube!
Cheers as always

Did my rear wheel last friday.Posted 4 years ago
Nobby Nic Evo, non ust on stans crest with yellow tape and sealant. Took a few attempts at getting the bead the pop. Finally managed it, was leaking so did the jiggle and rotate. Thought it was leaking a touch so laid on the side in a bucket as recommended. Did approx 30 mins each side. Has held most of the pressure so far. Loads better than the Rocket Ron I tried. Was as soft as a soft thing after a couple of days.Orange LadMember
When I set my wheels up tubeless I ran the bath and rotated them till I could see where the leaks were then gave them a good shake with that area at the bottom. Seemed to work well and they have stayed up since I was lucky as Mrs Orange was working that day so I got away with it.Posted 4 years ago
Right, still suffering from a slowly deflating tyre. I have now put it is a sink and it appears to be leaking from the base of the valve where it goes into the rim. Whilst under water I can see sealant slowly leaking out into the water but no air. I suspect there is a fault in the rim strip so might be sending it back to CRC. Any thoughts?

If you’ve got sealant in there I’d try holding the wheel out in front of you, with the valve furthest from you (if that’s where it’s losing air from) and adopt a ‘panning for gold’ motion, to slop some sealant around the base of the valve on the inside.
Schwalbe tyres always leak a little IME, but the snakeskin sidewall variety are much better,(and feel better on the trail too, at lower pressures). HTHPosted 4 years agojohnhighfieldMember
If air gets past the rim strip / tape it tends to get into the hollow section of the rim & comes out through the valve stem. I tend to use several layers of electricians PVC tape wound tightly onto a clean rim to seal it. I have tried to use yellow tape but it was too wide for my rim & did not seem very flexible. I also use some mastic on the inside of the valve stem as it goes through the tape for surity.
I’ve just put a new set of Racing Ralphs on a new set of Crests which were incredibly tight – wrecking a set of tyre levers. After using up 4 Co2 cartridges with soapy water I had to resort to my compressor to get them to ‘snap’ into place.Posted 4 years ago
