I went for a ride today and when I got home I saw tire sealant leaking out of my tire’s sidewall. I found a goathead thorn in the tread, not sure why it was leaking out the sidewall. It sealed with little tire pressure loss.I’m kind of impressed it actually ‘worked’. I wonder how well it will hold up when I ride again. I have spare tubes and my LBS can get my odd sized tubes in a week or two.
