I recently bought a new bike that came set up with tubeless tyres.
I suffered a burp on the weekend, which resulted in a small hole to the tyre wall (I think I rode over something hard after the tyre burped).
I've taken the tyre off to inspect and the sealant has hardened/gone off (it's about two months old).
Should I clean out the old sealant (brand unknown) and start a-fresh? Or just lob in some Stans?
Cheers
I got a small hole in my sidewall. My sealant had gone off too.
What I did was cleaned the tyre at the point inside and out and stuck a patch on both sides.
Scraped the sealant from the tread part of the inside, but left the old stuff on the walls - didn't scrape too hard, just got all the lumpy stuff off. And topped up with 2Oz of Stans, and waved it around/left it on each side like it shows in their videos.
Seems to have held so far... haven't ridden it yet - but it did seal up one other little escape from somewhere right in the middle of the tread...
Thanks for your thoughts, I'll give your suggested approach a go over the weekend.
Id remove only lumps and dried pools of sealant. The dry thin layer promotes quicker sealing down the line... to be honest though if it still sounds a bit sloshy, just bung some more in.
