My front GP4000 picked up a small slice from a piece of glass (I pulled it out and saw it). It didn't quite go all the way through and flat while riding, but did so enough to cause a slow leak. I know you can boot a tire but is this the kind of "hole" you boot or just leave it alone or is there another form of repair? It has about 2,000 miles but lots of rubber left and was hoping to move it to the rear eventually.

It is a little bigger and deeper than it looks in the photo.



Thanks.

Small piece of duct tape should work on the inside at the cut.
Make sure all of the glass is gone.

I have heard good results with Shoe Goo.

Never had a reason to try it myself though.

Never thought of duct tape. Thanks.

So just plug the hole a bit with some shoe goo to maybe keep it from getting worse? That plus the duct tape might work well. I don't have goo though so I'll just start with tape.

I have been using Shoe Goo (Black) to repair holes like that for a long time. Fill with Shoe Goo and scrape flat with a putty knife, and you are good to go.

Do smaller cuts need to be repaired?

I check them for glass, then apply some super glue.
It may be a waste of time..........

That's not a big cut -- I ride with stuff like that all the time. A boot would be overkill, but *if* there is damage on the inside, I would use a regular patch. Otherwise use nothing. I would not use duct tape as it's more likely to rough up your tube. Don't mess with shoe goo or filling the hole.

Having said all that, I'd probably replace a tire that had 2K miles on it. But maybe your roads are smoother so you get more mileage. BTW, almost everyone here (including myself) recommends against rotating tires. Use the search function to find out why as there are quite a few threads on the topic.

Duct tape won't hurt your tube.

Edges of the tape can be sticky and friction on the surface of the tape can make it grabby compared to alternatives. That it's thick compared to other varieties of tape will not help things.

I still think a patch is a better way to go if anything is used. If the solution must involve tape, electrical tape strikes me a better choice for smoothing out the inside.

Try a piece of duct tape....it will do the job for you.

Should you need proof, I have some.

I rolled over a pointy metal object, which punctured the tire and gave me a flat. The cut in the tire is tiny, would super glue help hold it together better than Shoe Goo?

Also, do you apply from the inside out, or the outside?

I'm sure it can be used, and I certainly wouldn't shy from it in a pinch.

But my experience with duct tape doesn't age particularly gracefully, particularly against any abrasive action, and the adhesive is particularly goopy. Duct tape is like vice grips or WD-40. It can be used for all kinds of things, but it's rarely the best choice.
