Not sure what to do here. Basically Stan's No Tubes used, I noticed a small amount of deflation although wheel hadn't been ridden. Has been topped up with sealant but has again deflated, although not much.
Any ideas please?
Thanks. 🙂
Any bubbles forming on the sidewalls? I'd shake it about and watch for sealant around the valve and spoke nipples to. Also what tyre have you used, I never had much luck with thin side-walled non-tubeless ready tyres so always use TR or UST tyres now.
I must confess my lbs did this for me. 😳 No bubbles, I've been shaking, lying horizontal etc. New wheels - Stan's Crest with Nobby Nic UST. Funnily enough, the other wheel is fine!
Aye probably loosing air through the sidewall, leave it on its side using a bucket overnight & do the same with the otherside the next...
Have you ridden the wheels at all? When I first went tubeless, the tyres deflated fairly quickly - a matter of days - but then I took them out for a short spin round the block which seemed to distribute the sealant nicely & they then stayed inflated?
Have you submerged the wheels like you would with an inner tube to see where they are leaking from? When I initially did mine, I hadn't tightened the valve lock nut up enough and air was pouring out of the valve hole in the rim.

This works well too.....
Ah, hadn't thought of riding! As I said, it's been laying horizontal, been shaken, turned over, left again, shaken. Checked valve and all nicely tight there.
Stupid question - can you actually have too much sealant in tyre?
Not in terms of getting a seal you can't but in terms of weight you can :p I normally put 60-100ml in mine anyhow which is a bit more than recommended but then I can still hear it sloshing about after a year in one wheel.
Edit: Riding on it is a good idea to, can't beat that for sloshing the sealant about - assuming it keeps enough pressure to be ridable
You need to ride them before they seal properly. they will always lose a little bit but after a decent ride they should stay up
I've had this issue, in fact I've found a bit of deflation over a week or so quite normal. I inflate to 50 or 60 just to make sure the beading is nice and tight, deflate to normal 30-ish then ride. No problems.
Use plenty of milk the first time and then go and do a decent ride - usually works for me 🙂
I had the same problem with flows and new nobby nic pacestar tr tyres. When i set them up my forks were away being serviced. They would stay inflated then suddenly drop a load of pressure. This happened a few times over the week before I rode on them. A ride later and they've never dropped air again. Done 500 miles on them so far with no loss and run the front around 23psi
