Somebody correct me: I think the 225/60 tire sidewall will be 2.25cm (7/8") taller than the 225/50 sidewall. Double that for a mounted tire (sidewalls above and below) and you have an assembled wheel (rim+tire) with an overall diameter 1-3/4" greater than your 225/50. This raises the car by 7/8" more from the road but reduces your clearance all-around between tire and wheel well by 7/8".
Or maybe I'm wrong.
Be sure to do the math and clearance measurements before you buy, yes? Or just drive Z to a pro mounting shop and ask them. They can tell by looking if the 225/60s will be too big if you love speed bumps and corner like a demon.
16" for new tire/rim size is right. The tires will fit your old rims.

@zcrazy4life what exactly are you trying to accomplish with this new tire size? Generally it's best to stick with tires that will keep the outer diameter as close to the original as possible, which I believe is about 25". This way you'll have fewer clearance issues and no speedo/mileage issues on your dash.

Rupe is spot on about that.
Increasing wheel diameter will put major errors into your odometer and speedometer, reading as much as 7%-8% low. The speedo error can cause surprise speeding tickets when you think you are running right at the posted limit...

I do understand the math I believe. If its a 225/50. The width is 50% of the 225? Correct? The only reason I wanted to know is b/c a guy gave me a brand new set of Yokohama's, but they're 225/60s. Was not trying to be dumb or thinking that I would gain anything from it.

That's a good deal on tires. Why not have a couple of them mounted on borrowed 16" rims, put 'em on your Z and find a speed bump or two, a vacant parking lot for sharp turns. You'll hear them if they contact the wheel well or the fender.
Your math looks right to me.
