Newbie to tubeless last year, digging out the racey wheels which have been in the cellar over the winter. I can still hear a little bit of sealant sloshing around but certainly less than before. Do I need to add some or should it still be OK? Is there a point where you need to wash out the gunk and start again? Thanks.
Sealant - How often do I need to top it up?
If you can hear it sloshing then it should be ok. If you can't hear it then it needs topping up. Also, if you get a thorn through the tyre, the sealant forms clumps on the inside which break off and start to rattle, therefore if you hear a rattling then it's time to remove the thorns and patch the tyre on the inside.
It depends on a lot of things. Some tires are more porous than others. Hot, dry weather dries it out faster. My bike spends a lot of time in the covered bed of my truck and it gets pretty hot in the summer. I typically add about 1 oz of sealant every month or so in the summer, less often during cooler weather.
