These are the things that cause flat tires:
1) Improper tire pressure. Ensure that your tire pressure is where it should be every ride. This, sometimes, means that you will have to pump your tires up before each ride. Flats caused from this condition usually have two punctures, close together. The punctures are often time referred to as snake bite and are a result of the rim edges cutting the inner tube when going over a bump or crack in the road.
2) Improper installation. Ensure that you did not pinch the inner tube during installation. This will usually reveal itself upon pressurizing the tire but might not until a day or so later.
3) Road debris. You have to watch where you are going and avoid road debris. This is not always possible but you need to make the effort. If you do run through some crap (ie glass), stop immediately and clean off the tire. Be careful and don't cut yourself. If left uncleaned, that little piece that did get stuck in the tire will eventually work its way through the tire and into the inner tube.
4) Riding style. When you see a crack or bump in the road coming, ride light. In other words, legs bent and be prepared to lift your weight off of the bicycle ever so slightly. You will even become proficient at getting the front light and then the back, almost all at one time.
5) Something in the tire, rim liner or tire itself. Check the inside of the rim very carefully, looking for sharp rim edges or anything that could puncture the inner tube. Do the same for the liner. Then check the inside, and the outside of the tire.
If you are getting repeated flats, chances are pretty good that you have a thorn, or a piece of glass, or anything sharp, embedded in the tire itself. When you check, look at every square inch of the inside of the tire, attempting to sort of turn it inside out. Use a magnifying glass if you have to. My guess is that this is the repeated flat problem you are having.
An embedded piece, sometimes, is not visible until you stress the tire. Turning it inside out and making little folds, over and over as you go around the tire just might reveal the little culprit.
6) Rotten luck. Not much you can do about that.
Hope this is a help and, for my money, forget the gorilla snot and get decent rim liners, not tire liners.
