IMHO there is a big difference between being economical and being cheap. If this tire will be only used for short slow rides with wife and kids around the neighborhood, sure, why not? Otherwise, it will, of course, as it usually happens, fail in the worst possible moment - somewhere 50 miles away from home, during fast turn on the descent etc. Just getting back home may easily cost more than a price of a new tire, and if it'll cause a crash with possible subsequent repairs to the bike and medical bills... I personally like long rides on roads with less traffic, which often means far away from home and in some places without cell coverage - I'd never ever consider riding something like this.
