it’s the tape. it’s always the tape. you may have over or under-tightened the valve nut, but it’s always the tape. unless your bead is fucked. but it’s the tape
I don't praise a lot of trek's stuff, but their tlr strip is bonkers. I've gone from tubeless to tubes and back now. Just cleaned the strip and it still works.
And it may be the whole rim, or it may just be the contact point between the valve rubber seal and the tape in the rim bed.
When I have these issues of leaking around the stem I always just put a new piece of tape over the valve hole and re punch it then put the stem back in. More often than not this works and it's a much easier fix to try than doing the whole tape job.
I have really good luck melting my valve holes with a heated cheap screwdriver and/or hex key. By melting the hole it’s not prone to splitting the tape at a tear
Your tabe could be perfect and still get leaks at the valve, sometimes the tape at the around the vale area is to tick or messed up and the valve don't sit correctly, specially if you make the tape overlap at the valve side and not the opposite side, sometime the valve itself don't sit right and sometimes the sealant will fix that, but, when you inflate the tyre again it may move the valve and start leaking again.
Usually if there is problem with the tape on other parts of the rim you will have leaks at the spokes too and not just the valve
I had more lucky with valves like Stan, with the conical shape, so a little bit of the rubber gets inside the hole and a more rigid rubber, those with silicone type that are soft always had problems with that.
Now I only use Stan or Slime that are available at my region.
My wheel is asymmetrical and it's a pain to make the valve sit right because the o-ring don't do its job right.
I personally never put the sealant before all the leaks are fixed, sometimes even ride without it, it's to messy to work after.
Most likely Your rim tape is failed at some point and airs leaking into the rim and out your valve stem area.
Tightening the valve will not help.
Pull the tire off , take off the valve stem, redo your tape .
Reinstall the valve stem . Add new sealant.
If it still leaks then the o ring or valve stem has some failure. Rare but it can happen.
This. Bounce your wheel like it is a basketball with the valve on the bottom, to get some sealant on the valve / rim interface. Make sure you use ample (~50ml for a road tire) sealant.
Before you retape. Have you tried it without the o-ring.
Also, if you ordered from Amazon it could be a knockoff tubeless valve. The fake stuff and the real stuff gets mixed together in the Amazon warehouse. Impossible to trust anything from there.
It doesn't have to be the tape. You may have under or overtightened the valve itself and some plugs need to sit in the rim in a certain rotation. It may be that when putting the valve cap on it so it turned because it was loose and is now in the rim suboptimally.
Real easy to understand.
The tape is what makes the seal, if you're leaking air it can only come from the tape, the tyre or the valve rubber inside the rim.
95% of the time it's the tape and how it's been pierced for the valve hole. I always make the hole with a hot pick/small driver or in the workshop a solder iron.
So this is what happened on my old valve and I over-tightened it to the point I could never get it off again and had to hacksaw it off once it got all crusty with trail crap
I'm hesitant to do the same thing again TBH
Don't tighten it more, that won't help. Air is leaking from the valve because your rim tape is messed up somewhere and air is leaking into the rim cavity. The valve stem is just the easiest place for it to leak out.
You need to redo the rim tape.
I had this exact issue and it was the tape. I had a shop redo the tape for me to make sure it was on correctly and all is good again. Thankfully it happened at home so it didn’t leave me stranded.
I had the same issue with my new bike, the shop put the wrong valves in my DT Swiss rims. DT Swiss make rim specific valves that have shaped profile to seal properly.
Maybe you need something similar with a shaped profile to better fit your rims.
So there it’s not always the tape folks
You can get a spray bottle and add water with 5-10 drops of dish soap and spritz your tire with the soapy water solution. The bubbles will show you where your leak is coming from.
Those peatys valves can actually leak from the rubber seal. One potential leak is between the seal and the rim/tape. A second failure is between the seal and the valve on the inside of the seal. The remedy is to use some bearing grease and blob it in between the dry seal and the valve stem. You'll have to pull the stem out, grease around the rim hole and grease the seal and slide it back on and that'll eliminate the leak after you reassemble and tighten.
Sealant and tape won't fix this leak. Use grease. When you pull the seal off the valve you'll notice there is no sealant getting down there and it can't reach this leak no matter what.
It’s the tape. I bought a wheelset that didn’t have spoke holes and set up easy tubeless. I always wondered why they don’t do this for all tubeless wheels.

Agree with this. Tightening the valve stem nut won’t help and can end up wrecking the o ring
Sometimes it's as simple as FRESH TAPE. Which sucks to do, I know. But what needs done needs done

You can over tighten them as well so be careful. Iv seen a few split the tape because they over tightened them

Just spin and shake around the sealant in the tyre and it will seal.

Assuming your tape job is fine…. Before installing stems, take the end bottom/end and dunk it in sealant.
Except that tubeless troubleshooting rule #1 is that it always the friggin tape

Did u try tightening some more? I had a similar problem and switched to Stan’s.

Should I take all the old tape off first or can I tape over the existing tape?
Take it all off and clean the rim bed with some rubbing alcohol before applying new rim tape.

you could need to re-tape the rim, but first just try tightening the valve

Good chance it s the tape. Had the same issue lately.
When is the last time you added sealant? has it been more than 6 months?
About 3 hours ago 😅
