Vittoria Normalcross

I have two NOS Vittorria Normalcross tires that will not hold air. They have never been glued. I am thinking of sending them to Tire Alert to have new tubes put in. My question is are these really useful for anthing to then mount up? I was thinking a front and rear setup for either really dry, bedded in courses (rare in New England after Suckerbrook) or for the frozen ground. Would it be better to just mount one in the front? They look like they could be fun, but would it be worth the effort and $40?
