At the same tread width and total diameter, they should have very similar contact patch area; but the higher sidewall simply has more air; so it could support more weight. If you are looking for a certain drop on the sidewall (bicycle style), you might need less air in the larger profile. I'll read about the casing tension, that probably has some to do with drop; but think about the supported weight as well.
