I need to buy a rim for a spare tire but I have no idea how a rim is sized, is it the same as the tire? Also are rear and front different? My C-Max is a 13 SEL.

I've had no problems with mine however getting it fixed Tuesday anyway. However shortly after I received the postcard not long ago I noticed the car wont sense the key fob and now I have to manually unlock even though I JUST had the battery replaced, this wouldn't have anything to do with that would it???
