Deep enough cuts to replace tire?
 

Coming back from a long ride with quite a few ups and downs, and have found a few cuts of various depths on the rear tire. Please see attached pics. The 1st and 2nd are deeper (I actually pulled glasses out of them, ~1mm or deeper), and cuts in other pics seem minor (I think)

Would you replace the tire? This one has just over 1K miles.

That tire is cooked, in my book.

The picture of the inside of the tire is important. Do the cuts penetrate and how badly?
Minor penetration often is not a problem, when it's wet though they can become troublesome. Minor holes can be patched / booted on the inside. Some folks use shoe goo and such on the exterior cuts.

No, put a dab of Shoe goo on them and they will be fine. If the cut has nicked the casing and/or the the tube shows, I replace the tire or put a boot in if the tire is relatively new, but otherwise I just keep riding on it.

From the look of uneven wear it seems you have quite a few miles on these already. I hate worrying about flats and even more about blowouts so I would probably replace these.

If you're worried about the deeper ones but the tire still has a lot of miles to go (say, 50% life or more since it's on the back, and they're more of a pain to change) put a 1" x 2" piece of Park tire boot on the back side and keep an eye on the cuts for a ride or two. Once you've verified that nothing's getting worse forget about them and keep using the tire.

I replace my tires more frequently than I need to because if I’m worried about those cuts on a fast downhill, I’ll get all I’m my head and won’t be as focused as a should be.

That being said, those look fine, as long as they don’t tear the casing.

I’ll periodically pick bits of road and glass out of my tires with a tiny screwdriver. Makes me feel better.

Yes, glass has to come out otherwise it just works its way through.

Shoe goo? Interesting. I've heard people use polyurethane glue to fill the cuts (assuming it hasn't pierced through the casing), similar effects?

spend the money on a new tire and stop worrying abut either the fix or the longevity

1000 miles? Id replace based on that alone

I don't know about these specific tires, but I get much more than 1,000 miles out of a tire. I have used shoe goo, crazy glue, really anything that will stick in there and give it some support and have never had an issue as long as the cut isn't thru the casing.

Please replace
 

For safety reasons
You noticed it and it must concern you

On the lighter side the time to photograph and post that tire would have been changed and recycled :eek:

Hmmm am I not seeing this right and missing a big cut? Those are teeny. In nyc you can get one of those within 100 miles, you would be buying new tires every month. I dont see a problem with any of those. I have though put a dab of glue on some cuts but all bigger than those.

+1. I don't see any bulging around the cuts, which suggests the casing is intact. If you see any bulging that's not apparent in the photos, then yes, replace the tire.

If you see no bulges, I confirm Shoe Goo works great for filling small cuts and lasts the life of the tire. As others have mentioned, you might wish to replace the tire because it's old-ish with 1000 miles on it (I get 1500-2500) and *it bugs you*, but the cuts themselves don't affect the safety of the tire.
