The sidewalls are therefore super thin, and will sometimes seep for a long time. It’s a sign of how incredibly supple they are. And I can attest that running those babies at low psi is nothing short of cheating, compared to people running thick-walled tires at 10-15 psi more.
I check my pressures every ride. If the tires need a few psi, I top them off. The need for air after a day is not a defect. It’s a feature.
If one can’t live with the looks of some seeping, send them back and get thicker tires.
And go slower.
You do realize that the OP is on WTB tires, right?
I’ve run plenty of WTB tires, and his are not performing as expected.
And I really doubt that I run my WTBs at 10-15psi more than you use in your Compass tires.
No, you are right. I’d lost track of his tires. My comments were obviously focused on Compass tires. So forgive my error. I’d still say, however, that seeping is an indication of a supple tire. As long as it holds air as he’s described, I’d be ok with it. But then, I’m used to tires that seep.
Smooth is fast. Supple is efficient and smooth. Low pressure is smooth and fast IF it’s with a really supple tire. Flats are REALLY slow. It’s finding the right combination that’s fast. You may indeed run low psi. I was making no inference about you.
I have to say that after a few rides that I am really happy with how the WTB Venture rides and handles on my dry, packed routes. I truly don't want this to seem like a WTB bash as I think the tire is great and if it bubbles forever but rides nicely, I'm ok with adding air each time I ride as I do/check before each ride regardless.. If it were to start losing air fast enough to affect a ride, that would of course be different but that has not been the case so far.
The tire continues to bubble; if it has decreased any, it is not a significant change. When I bought the Bont sealant, I was told to really agitate it before installation. I can't say that I have been the best at doing that so it may be a factor. I am going to remove the Bont sealant(whatever sucks out easily) and add Orange Seal Endurance and see if that makes a difference. I will be away for a few days, hopefully catching some bass/social distancing. l'll report back on the bubbling/pressure loss with OS Endurance in a few days..
Again, thanks for the replies and knowledge sharing. Ironically, I have been riding tubulars on the road for at least 25 years; I can attest to their being much less difficult than tubeless!

No worries, I didn't take anything personally. But I do think that, with WTB tires, the OP should contact the seller - after trying Orange Seal. It's all I've used with WTB tires, and I've never had ANY sidewall bubbling - and they all have held air well enough that I only top them up about once per week.
By the way, I run my Resolutes (43mm wide) at <30psi without any problem. Haven't tried Compass tires, but might get some for one of my bikes to see what the fuss is about. But probably the Standard casing - I need to make it home from a ride!
Agreed, WTB TCS tires should not bubble sealant through the sidewalls. I've used Byway, Horizon, Exposures and they work great with Orange Seal.
I got a pair of Compass Switchback Hills standard casing and they leaked Orange Seal through the sidewalls for a week even after laying the tires horizontal. Each day less and less bubbling. The ride though was better than the Horizon or Byway.

So, after about 36 hours with OS-E, there is some bubbling but clearly less than previously and it has lost less air than it previously would have. So, I'm thinking the sealant may have been under agitated. Hopefully this is the closing of this chapter.
For those who were wondering, the bass were practicing social distancing with admirable discipline..
At my end still making stupid sh_t mistakes. So I bought the Donnley PDX 700 x 33 cyclocross tires to use as a back up mud wheel set They are tubed tires. I set them up ghetto tubeless. Went to my LBS tonight by appointment only. He said I would shred the tire and with little pressure popped the tire off the rim. That could have happened to me on a downhill. Back to cleaning out the tire and putting tubes in them. gravel riding 101 mistakes
Really didn't want to start another thread so hopefully the op doesn't mind me asking this ? I have only been riding tubeless this last 2 years. At 200 lbs. my sweet spot I have found is 40 lbs rear 35 lbs. front for gravel and 45 rear 40 front if it is more roadie. Curious what that relates to on 700 x 33 tires with tubes.

Thanks Zman
No, this is my thread and you can't have it..
Hopefully the same great folks will answer your question and keep the positivity flowing. My quick response is that at that weight that might be a bit low low for 33mm tires..

Well you have to ride higher psi with tubes than you do tubeless so I have to try and dial in that sweet spot. I was hoping to get some help to get a sgtarting spot.
