OK, I'm new to tubeless.
I have seated the tyres on the Crest rims fine, inflated without sealant to fully seat beads, and the only place I can sense air coming out is from a small sidewall scrape, about 1cm long. There's one on each tyre. If I put sealant in, will the sealant be able to seal sidewall damage like this?
I don't want to make a mess of everything with sealant if it's not going to work without a tyre repair...
