Should I replace this tire?

Rolled over a glass bottle a few days ago... on my third ride with a new GP5000 28mm clincher tire. The long scratch is cosmetic but there was a puncture of the casing. The tube did not puncture, even after another 50+ miles of riding (I was a long way from home).

I think this is right on the boundary of the acceptable limit... I'm inclined to consider myself lucky enough that it didn't blow and just replace it... but am I being too cautious?

That looks like a sidewall puncture. I would not use that tire.

Tough call, damage on the outside surface look bad but inside damage looks minimal. You may want to try overinflating tire to see if there is any bulging in the area of damage but your call.

To make a point- I think the OP should mount this tire on the front wheel, inflate well over the max pressure and then ride down the steepest hills in the area...

Of course the OP should replace a tire that is damaged. Any use of a damaged tire should be for as few miles as possible, like getting home to replace it. Andy

Side wall cuts are a bit scary to me.
It may be good for quite awhile, but eventually it's going to break 1 thread too many.
Do you pack a spare tire?

If you decide to ride it, I'd at least glue a patch on the inside or some type of boot.

If it were my tire that would never be ridden by anyone else I would patch the inside, put it on the back wheel, and watch it for any changes.

I'd only replace it if my next rides were something important to me that a flat would ruin. Otherwise, when I'm just riding my plain everyday routes and within easy reach to have someone pick me up or just don't care about time, I'd be happy to leave it on and see if it ever becomes anything.

If a few of the cords are cut and the sidewall puckers out when inflated to riding pressure. Then I might think again about it. If the tube is showing through the pucker, then I'm changing it..... unless I have to have it to get home. But then I'd boot it too.

I've used tires with side wall cuts. I've glue a piece of denim inside the tire and placed the tire on the rear wheel. Then again, I have many more years behind me than I do in front of me. So, at this point I don't care.

Thanks, all. My risk tolerance is low enough that I'll just throw a new tire on it, just to be safe.

I once did that to a brand new Gatorskin and I really tried to save it with a boot and cement, but at 100 psi I just couldn't find a good way to fix it. No matter what I tried it still had a bulge. At the time I could hardly afford the replacement tire but I still took the safer route.

Peace of mind beats increasing paranoia the further you get from home.

Sucks to have to replace a new tire but better than a trip to the ER.

The above is me. With that tire, you could be a ride away from a bad crash.
