As title suggest. Got a small 3m slit in tread of tyre. Sealant took a while but fixed it. Added more sealant. Tyre holds pressure but it still weeps. Not much. Should I just leave it or glue it?
Have you tried using a repair plug? If it's still weeping then the hole isn't properly sealed and you run the risk of the sealant failing when you are in the middle of nowhere.
stick a patch on the inside.
Sounds like the hole is just too big for the sealant bits to fill, or perhaps they’ve congealed elsewhere. As Klunk says, patch it. I bought a load of proper mushroom patches off eBay - with a metal sprag that you can pull through the hole from the outside. Used with the proper rema tubeless glue, these provide a permanent repair and will render the tyre good as new.
small 3m slit
To be fair, 3 metres is a huge slit. I doubt that'll seal. 😉
Ha, missed an m. Felt like a 3m slit the amount of sealant it pissed out initially.
