But I'm just asking in general: is large rim/thin tire or small rim/fat tire lighter?
it depends on what is on your car now,you could possibly go up to a larger rim and maintain the same width, but this is usually unlikely. considering the vehicle you have you more than likely would not benefit from larger wheels and tires with lower sidewalls.

out of curiosity do you know what size tires you have? if you dont know the size is easy to find, on your car it should look something like this: p195/65/15 but your numbers will vary.
in case you dont know this is what that line means:
195-tire width (milimeters)
65-aspect ratio (percentage of tire width equal to sidewall height)
15-wheel size

definately look into a smaller set though.
