Good idea. The Innova Swiftor might be a good one to use as the inside tire. It has a pretty thin sidewall, so if you wanted, it would be easy to use a pair of tin-snips to cut off the bead... Plus, at about $10 a tire, it's probably the cheapest slick tire you can fine.
After two flats in as many months, I had to take action last night. When I put the new tire on the rear wheel, I also installed the old tire INSIDE the new tire, along with thicker tube.
I'll do the front as soon as I find another old tire to stick in.
There is no reason to stick a NEW tire inside another NEW tire. Recycle the old tire into the new tire.
Also bought tire patch kit and small air pump to carry on "The Dragon Lady".
Just ranting here,
Why can't "they" make a good, heavy duty tire for bikes? Such weak, crappy tires on a motorcycle or scooter just wouldn't fly. DOT regs. should apply to bicycles too; somewhat.
I think...
OK, I'm done.

Every time I get a flat on my way to work my attendance suffers. It's a good thing my employer is lenient about this. Another company might threaten to fire me.
Then I'd have to give up my idea of commuting to work via bicycle.
Then I'd have to pay $81 for monthly parking and more $$ for gas.
eastwoodo4, after I mounted the rear tire, I avoided the bikepaths with broken glass.
Now I ride on the main road and claim the curb lane. There is far less glass on the road than bikepaths. With double-tire casings I hope to have flatless rides like you.
I'm in the process of building a push trailer, using a 16 X 2.125 knobby tire and 16" BMX plastic wheel. I'm also using double-tire casings here.
Double-tire is the best idea of flat protection I've heard of.
