I had a tire that went completly flat, added sealant and then it wouldn't hold air, the tape failed.
Now, I see some rust on the spoke nipples, and I'm wondering what you would do next?
So far, I'm just airing it out.
I don't have anything small enough to get in there and brush off the surface rust, it would need something like a 1/2 size Oral-B rotating brush head.
Would you spray with something?
Try to loosen or tighten the spokes so they do not freeze?
