I had to refill the tubeless sealant to both my tires this past January. Now I did my research before and I do know that you will have to do this, but I wasn't expecting it to be this soon.
It started with the rear tire. I inflated it once in preparation for the next day's ride. Luckily for me I used the bike trainer that afternoon because after using the trainer I saw that the rear tire had no air pressure left. So I checked and there were lots of leaks.
Two days ago it happened to my front tire as well. I inflated it for a ride the next day, got around to riding and went home. The next day it had no air left.
When I re-filled it with sealant I decided to use more sealant than before. Just taking precautions. Also with the front tire after applying sealant it was still steadily leaking from somewhere. So I unscrewed the Presta valve core and poured some more sealant through the valve stem. After that the tire held air.
So after this past month's experience I've decided that next time I need to re-fill the tire with sealant my new process will involve:
- Unseating the tire and pouring the sealant directly into the tire by removing one side of the tire from the rim. Then I'll use lots of sealant, because the sealant I'm using might need more instead of the recommended.
- Once the sealant fills the gaps and sets I'll fill it with air and do the usual ritual involved with having new sealant in the tire.
- Remove the air, remove the valve core, then pour some sealant through the valve stem. This is just in case there are gaps near the stem that the sealant didn't get.
- Refill with air and check if it holds pressure.
I do like the fact that I was able to upgrade my bike to tubeless tires even if the rims weren't tubeless ready.
Out.
