I didn't think you were suggesting it, just saying it isn't a good idea. I do also agree that driving regularly is really best for getting your money's worth out of a tire. Bad thing about belt separation is that there's any number of things that can cause it, overstress from overloading/overinflation, potholes, overflexing from underinflation, or simply the fabric or steel belts 9depending on tire construction) simply rotting from deterioration of the rubber encasing them. Been in the tire business for a long time, and I've seen tire failures from all of those reasons.
BTW, ever wonder why tires turn brown? That's the oils in the rubber compounds doing their job. The oils oxidize, rather than the rubber itself. Unfortunatly, even they only last so long.
