need spare tire

[GhettoPop]

i need a spare for piece of mind sometimes.  i'm not too worried about the condition of the spare wheel, just want something i will cover up in my trunk and use for an emergency, not a show piece.  I have the following wheel/tire combo:

Cragar SST Wheels
front 14x6" w/ P205/70R14
rear  15x8" w/ P275/60R15

what size spare wheel/tire should i get? thanks.

measure the diameter of the tires you are using & get one close the same height , if you have a sure grip get one closer to the size of the rear tire if the height is different
