In the end you either want one the exact same so you can rotate the tyres for even wear and you can drive a decent way on it if you have to or a space saver to get you home. Anything "nearly right" is useless, on the rear its different rolling radius can stuff your diff, on the front the steering will pull so its only good for a "get you home" , Since it will cost about the same as the exact same correct wheel why waste time and money? Every time you look at it you will think "why didn't I buy a matching wheel and tyre?"
