My tubeless tires/tyres have a few cuts around the tread pattern. They are each around 3–4mm in length. I've been proactive with topping up sealant and have not had any flats since riding with these tyres for the last year as a daily commuter (only about ~4km/2.5mi a day).
I plan to do a 700km/430mi bike tour with these tyres on mostly sealed roads. Do these type of cuts warrant repair or tyre replacement?
I've seen folks online use Shoe Goo on cuts slightly bigger than this, or patch the tyre from the inside. It's my first time running tubeless so I'm not sure how proactive I need to be with them. They ride great!
The tyres are Panaracer GravelKing SK+ 700 x 43C.
Edit: I've also just noticed a distressed line or gash on the tyre's sidewall. Adding to this post as it's in the same spirit as the above 3–4mm cuts: something that hasn't affect the performance but might be problematic.
