I picked up a rather large screw on my ride today. I was always carry a spare tube so I was able to make it home. A couple of months ago I lost another tire to a large puncture (I know, I have great luck) and the resulting hole allowed the new tube to blow out. So now I'm questioning how safe this tire is. I've already replaced it with a new tire but I'm not quite ready to throw it out because it's only a couple of months old. My question is whether or not I should trust this tire. I've attached some pictures showing the inside and outside of the tire at the puncture site. I'll probably scrap it because I don't need to be riding around on a tire I don't really trust. Opinions are most welcome.

Yeah, I don't think it's worth keeping either, but that's just me. There are some folks who think installing a Mr Tuffy would work, though.

One thought for future tires - Conti Gatorskins or Specialized Armadillos are favored by those who ride in hazardous territory.

Safety first. When in doubt, I get a new tire. Hate to get a new tire though. I know the feeling.

Looks like it should be okay to me.

If the tube doesn't poke through the casing when it's up to pressure, and the tyre doesn't bulge, it's good to go.

Safety concerns over this = hysteria, IMO. The chance of a puncture is always there anyway.

Armadillo is branding on Specialized's flat protection, they have Armadillo in a wide variety of different tires from road to hybrid to mountain. one thing they all have in common, they are heavy and have a crappy ride.

I'm a convert to Vittoria's Randonneur series of tires, especially the "Hyper" for hybrid sizes. My son has been running Continental Gatorskin and Hardbacks on his skinny tire road bike, up where he lives the roads are always wet and there's a ton of broken glass from the rednecks' beerbottles, and they have held up really well.

Try a tube patch inside the tire over the hole.

+ 1,000,000. The tire is perfectly safe. If a tire is cut enough to present a risk of blowout, the pressure will pull the cut open making a visible (and feelable when riding) bulge. Sometimes (rarely) the inside of the cut can cause a pinch puncture, but a patch will prevent that, as will a piece of electrical tape.

OTOH, if on inflation to full pressure, the tire spreads visibly, it's days are numbered, so buy the replacement now.

Exactly.

You might even be able to use a small auto tire patch. Yes, these patches are a bit heavy, but (iirc) they often have a slight concave curve to them that roughly matches the inside curvature of the tire.

Edit/Note: you can, of course, position the tire repair patch opposite the valve stem so as to negate any possible "out of balance" caused by the "heavier" auto tire patch.

I'd try patching it as well while looking carefully for signs that its integrity is compromised.

Yup.

Back in the day I used to use the casing from a sewup to boot tires. A dollar bill will work as a temporary boot.

Given that prime, you can probably come up with something that works. My best brainstorm would be the material that USPS uses in some of their packages.

gaffers tape!

My primary tire experience is with mobile home tires, which usually don't take a tube but can. Those take much more punishment than a bike tire.
Yes, patching the tire on the inside will work fine. You also could just use Gorilla tape, radiator hose tape, or some other decent tape. The tire repair doesn't need to be air-tight. It just needs to stay in place and contain the tube. The tire won't rip on it's own.

I've always used electrical tape with no issues.
