I'd be grateful for an explanation of the various merits of "anti-puncture tires" (ie. Tubes?? Belts??) and their overall effectiveness. Is the tire =sidewall= reinforced in any way, in addition to the tread area?
I'm a beginner bikerider, so advice would be appreciated. Thanks.

"Puncture resistant" tires/tubes are just that. Note that no one sells "puncture PROOF" tires/tubes, because they all can fail. One tire that gets high marks for puncture resistance is the Specialized Armadillo series. There are many ways to reinforce a tire, including weaving kevlar into the casing, putting kevlar belts under the tread, and thickening the tread. It is axiomatic that increasing puncture resistance increases weight and decreases ride quality. As an example, every few years someone comes out with either a solid (e.g. foam filled) tire or a very thick walled "airless" tire, and they never sell well because the ride is so poor (harsh, heavy, unstable in corners, etc.). "Thorn proof" tubes have been around for a long time (35 years at least) and have never caught on for the same reason. The very thick rubber of the tube weighs a lot and makes for a poor ride. In the end, you have to balance weight and ride quality against flat resistance. IMO, unless you live in a really bad area (glass, thorns, metal) you're better off to just ride "normal" tires and to learn how to change a tube - it's not that hard. Even with puncture resistant tires/tubes/tire liners, you still run the risk of getting flats, so no matter what, you have to know how to do this basic task.

i heard about one guy who would use a thorn resistant tube, then take a normal tube cut it in half, along the seam, and then put the other half inside the tire/over the other tube. He rode from Florida to alaska and got only two flats. Its a lot of weight in the wrong place but worked really well.

I've been running Vittoria tyres with their PRB (puncure resistance belt) for a number of years now with great success. Before I used them I averaged 1 flat per month, since I've been using them I've had about 3 flats in nearly 2 years, seriously, no joke.

Check out their website for an explanation, go for the ones with a PRB and they're dirt cheap.
