What's your favorite tire/liner/liquid combination to prevent flats?
I'm a long-time commuter and I view flats as part of life, but I think it's possible to minimize their frequency. I started using plastic liners (like Mr. Tuffy) a few years ago and I find that I get many fewer flats than I used to.
I recently put together an electric kit bike and it occurred to me that I *really* don't want to get a flat on it because it's a serious pain to change a tube on the thing and it's appallingly heavy to push. So I want to get some serious puncture resistance. The bike's electric, so I don't mind heavy.
So... Schwalbe Marathon Plus? Armadillos? Slime? What are your opinions?
