Bicycle Mechanics - Need to patch a tire?

I got a flat the other day from what was a fairly slow leak for a bike tire -- was able to just pump it up and ride the two miles back to my car. I replaced the tube when I got home (and patched the original tube to use as my backup), but I was wondering if I should have put something on the inside of the tire over the hole that I found there.

The tube just had a pinhole-sized puncture, and I was able to find a matching spot in the tire where something had poked through. Whatever it was, there was no sign of it -- just a gash of about 1/16 inch that was hard to find without a careful look.

So was I OK to just leave that as-is and remount it with a new tube? Or should I have put a piece of tape or something over the tire puncture from the inside?

Probably depends on the tire somewhat and the location of the hole. A big, fat, low pressure knobby is probably much less critical than a high pressure 23MM tire.
I'd of probably glued a patch inside the tire if I had ANY qualms.

If I can find the hole again, I'll usually glue a patch on it from the inside. I use those giant patches that most kits come with. For cuts that I find on the outside of the tire, I dab some Liquid Nails or RTV on my finger and rub it into the cut.... primarily to keep other debris from working its way in.

BTW... Make it a habit to carry a piece of thin cardboard or a candy bar wrapper in your repair kit. If you ever hit something sharp enough to gash open the tire, you can replace the tube and splint the tire's gash from inside with it... It'll get you home without walking there.

If you're in or around the IT business, see if you can snag a mylar anti-static bag, such as circuit boards are stored in... Those make indestructible tire splints.

Regular tire patch adhesive works well to seal up small holes like that. Open the cut with finger pressure and work some into the cut. Wipe off the excess.

Some cloth from an old pair of jeans or nylon tent material will make a good tire splint when applied with some patch adhesive. Let it cure before replacing the tube or cover it with some plastic to avoid adhering the tube inside the tire.
