Tubeless experience
« on: June 30, 2017, 08:20:31 AM »
Anyone notice recurring "wet spots" on their tires where a clear oily fluid is seeping through sealed punctures?  After nearly a year of use I have 6 or 7 wet spots on the rear tire that show up after the bike sits a day or so, but no air leaks.  I expected to see white spots from the Stan's sealant, but all I can see are tiny cuts that get wet overnight.  Shaking the tire, it still sounds like plenty of fluid inside so it doesn't seem to be hurting anything.

I've only set up 3 tires tubeless but they all "weep" water as you describe. Let them sit for an extended period and they drip on the floor.

I use Bontrager sealant.

I always get that with my Racing Ralphs after I've raced in PA. Pointy rock is unkind to Ralph.

With both Stan's and home brew sealant I get that now and then.  I take that as an indicator it needs changed.  Most of the time I see more is after the bike is exposed to a big temperature swing, or sits for a while as mentioned.
I have had some tires where the solids coat the casing, not staying mixed in the carrier liquid.  That might be the situation you have if the sealant is a year old and it's time for some fresh.
