Should I change my tire?

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

Should I change my tire?

Hey,

Today I was riding and my tube went when the side of my tire drove over some small stones that were on the road. Now the tire itself is generally okay, but it does have a very small hole where the stone punctured the tube and where the air came out. The tire has about 2300 km on it and it's a Vittoria Rubino Pro. Is it okay just to replace the tube or will I get more flats if I continue driving with it?

Thanks!

You can temporarily use a "boot", a piece of stiff rubber to patch the tire but you'll feel a bump every revolution. If you don't patch the hole, it'll cause more flats. I'd just get a new tire.

The hole is so small (you probably couldn't stick the point of a toothpick in it) that it would be kinda hard to patch - that's why I was wondering, with regard to the small diameter of the puncture, whether it could be considered a negligable risk to continue riding with it. This is my second set of tires since I bought the bike in the ned of May, that's why I'm a little skimpy on spending another 25 euros for a new tire

You might be able to get by then if the hole is that small.

You might be riding on under inflated tyres; a lot of flats and tyre damage is caused by not having enough pressure in them to "push away" or deflect the small stones and debris in the road. The tyre deforms around the stone and the stone has a chance to dig into the rubber, causing a cut or tear.

I've had one flat in the past two years and that one was with a very old tyre that was showing the cotton threads.

Yes I understand the issue of underinflation that you mentioned. I have a Cannondale pump that shows bars and I pretty much always keep my tires pumped to about 9 bar and all the debris just fly away like little projectiles when the tire hits them. I also hadn't had a flat besides this one today in the last 3000 km.
The tire is probably also under a lot of stress since everywhere I go, there seems to be some repairs of roads going on or small parts of gravel appear out of nowhere and similar that I have to drive through.

as long as when you pump your tube up it doesn't look like it is trying to buble through, it sounds like you would be fine. if you want to be sure about it, I would use a boot as BBattle mentioned above.

Is the cut on the bottom of the tire that contacts the road or the sidewall?

StanSeven: sidewall

p.s.: actually when I went to check it out just now, I couldn't find the hole. On my cross bike I had a much larger tear in a sidewall so I bought a replacement tire, but didn't change it right away and went on to do a hill that had quite a lot of gravel and it didn't puncture. I think that for normal turning and such it should be ok, I'm just worried about small debris (which is pretty much everywhere, all the time, unfortunately ) on the road while making turns; if this puncture might affect the overall toughness of the tire
