Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Can this tire be saved?

I expect this is a dumb question, but I had to ask... this tire only has 800 miles on it, and it was around $40.

What I want to know is, can this tire be safely booted? I have one of those booting patches from Park Tool, and I was planning to install it, plus fill the cut with a little crazy glue.

Thanks in advance for any helpful replies.

It is toast... I had a cut like that and tried a repair to no avail.

At 800 miles your at a nickel per mile. Toss it and ride on.

I'm cheap. I might try to contact cement a boot underneath using a piece of old tire and then fill the gap with shoe goo.

Proof that I'm cheap is that I own shoe goo and don't toss old tires.

Then again, I'm also always looking for an excuse to upgrade.

That sucks - you can tell its a Conti. I've got 4,000+ miles on mine and still going. It's definitely not worth it, it could rupture and send you flying.

Back in the day, professional mechanics would fill cuts like that with black Bostik, which is a kind of adhesive/sealant. Never saw such a repair fail, though if you're really concerned, you could just use it on the back wheel. Dunno if Bostik is available in the States; but I'm sure a comparable product is available from other makers.

When I put the new tube in, I ran my finger around the inside of the tire, but found nothing. I saw nothing, either. The cut was closed when the tire was off the rim. So I put the new tube in, inflated it, and rode 11 or 12 miles on it. When I got back to the starting point, I saw the cut.

Boot it and see what happens, if there isn't a hole all the way through you might be fine. Put it on the back and don't race on it.

"Put it on the back and don't race on it." Yes, this is probably the most important bit.
:

If I decided a tyre is savable, I boot it with a thin piece of plastic from a plastic A4 folder. It depends how much the casing is damaged and/or how big the cut is. I've booted cuts your size.

Bootable if the casing is not compromised, otherwise, toast.

If the casing's not damaged and it doesn't bulge, I'd fill it with Shoe Goo and keep riding it.

As long as the boot stays in place, you'll be fine. Just make sure it's solid first.

I don't think it's salvageable. That rip could zipper open at any moment, boot or goop.

boot it from behind, fill with crazy glue and toss it on the back wheel.

Has anyone actually ever seen a tire tear apart due to a cut in the rubber? Unless the tire is cut right through the cords inside I don't think there is any risk of the cut expanding.

The problem is keeping the tube from protruding which a boot should handle. I would use it for a winter tire.

That cut looks like it goes right through the cords. And, yes, I've seen cuts like that zipper open. With a cemented boot in place.

The problem is keeping the tube from protruding which a boot should handle. I would use it for a winter tire.
The other problem is (If the cut is in fact through the cords), that any significant change in tire pressure (ie, running over a rock or something) will cause the tire to zipper open.

Of course, there's lot's of times where the "fugetaboutit" technique will last a long time, even in a part that is borderline failure.

I agree it's a problem if it's cut through the cords but running over a rock won't make significant change in tire pressure.

I've never seen such a cut "zipper open". The real problem is that it allows the entry of road grit and other trash, which can then damage the casing. That's why it should be filled or closed.

I personally would try some of these repairs/filling in with stuff only if I rode the bike locally and toodling. I dont know about you but even in town I can find myself going down hills at over 60k or 40mph, or going around corners quickly, so in the end it comes down to the risk of something weird happening in a fast or dicey situation. Having fallen off motorcycles and bicycles are varying speeds over the years, is it worth the 40 bucks? Only you will decide that.

drag though it was newish but hey, c'est la vie
