Well if you go 1" larger wheels then go 1" lower sidewall tires. Keeps it all the same. Otherwise your speedo will be off and read wrong not to mention the chance for fender and suspension trouble or even damage.

If you go 1" larger wheel size. You go 1/2" shorter tire sidewall height.

Actually no it really is gain an inch lose an inch. Plus 1 in wheel requires Minus 1 in sidewall. Check any online site.

Here is an example.

BTW I run 17" rims and low profile tires and you can see what they look like in my album if you want.

Yea gain an inch lose an inch, however you gain 1 inch of wheel size but you have to lose 1/2 inch of side wall. 1/2 inch on opposing sides equals your 1 inch loss.

You have to look at it from the top half vs bottom half from the wheel centerline.
Going from a 16" to 17" wheel gets you a 1/2inch gain in each direction from center. To offset this you need to lose 1/2 inch of sidewall in the same direction of gain.
