Also depends on the tire profile. the second number in the tire specs.
For example: 275/45/18. 45 is the height of the tire based on the percentage of the 275.

So if you put 18s on, you need to adjust the tire sizes so the entire wheel and tire isn't much larger or smaller than your 17s wheel and tire. Did I make sense?
