Tubeless tire slow leak (lemm.ee)

Hello Wrenchers, I took the plunge to tubeless this week on my 2022 Cannondale Topstone gravel bike. Getting the tires on wasn't too hard (just messy). I used parts from my local bike store, including 2 new WTB Riddler "TCS" tires, a new valve for each tire, and about 3 ounces of Stans sealent in each tire.

But now that they're on, they're both very slowly leaking. I did the soapy water test and I can see about 5 spots on the front tire and 2 on the back tire where bubbles appear (not at the valve).

Any tips for fixing this?

Thanks!

Some tubeless tyres I have had have held pressure indefinitely some have slowly leaked over time regardless of what I do, I think that is just the nature of the game.

You need to make sure the sealant is well distributed around the inside on that initial application so move the wheel around in your hands to try and get it to every part. Go out for a short ride after that and just try and get it everywhere inside. Failing that if you can identify where there might be a leak like you said tip the wheel so that the sealant will sit where you are getting the leak for a bit in the hopes that some will plug up that tiny hole.
