on the first two tires you have listed, that's only about an inch difference at the tread face... so that's not much IMO... and slightly different side wall height... in all reality, the sidewall probably is about the same height. I don't have time to run the numbers now, I'll try to later, but that size difference wouldn't be that bad.
Same with the other set you have listed.
