Tire Size Calculator

[LotusRenaultF1]

I'm looking to get new wheels, bigger than the ones I have. Thinking of a 16 or 17 inch rim. My tires are 195/65R15 I think which is on the LS. Common sense says as the rim increases, the profile should decrease in order to fit the tire. Problem is, I have no common sense lol. Is there a calculator for this? I know the way to figure it out is something like the first number multiplied by the second number or something.
