No war. Do a search and you will find lots of opinions on the subject. In general, there are better tires available for the larger rims with out some of the compromises of the performance 15" tires available but the 15" tires look more correct.

As for pressure, look around the BFG site or do a search here there is a formula for a good starting pressure that I posted some time ago. Beyond that you are talking tire temperatures, desired ride and handling charactoristics etc.
