Replace Punctured Tire?
I ran over some glass on a ride last weekend early into my ride and the glass cut through the tire and tube. I replaced the inner tube on the spot. The glass left a small gash in the tire but I didn't think much of it. I completed the ride, which was about a 25 mile loop. I got the flat about 2 miles in, so I rode about 23 miles with no problems.
I inspected the tire and there is a small hole maybe 2 mm or so in diameter. I decided to patch the inside of the tire as a precaution. Do you think it's safe to ride with? Obviously, I completed one ride with no problems. The patched tire is on the rear. I've ridden several tires in the past with holes worse than this one with no problems, but I'm wondering if there is a general rule of thumb about whether one can or cannot continue to use a tire based upon size of the puncture.
For reference, this is an espoir sport 25mm tire.
