The 2005 Kia Spectra EX bolt pattern is 4-114.3 mm. This means there are 4 lugs and the diameter of the circle that the lugs make up measures 114.3 mm or 4.5 inches across. To get a close measurement of your 4 lug bolt pattern without a bolt pattern tool you should measure from the center of one lug to the center of the lug across from it.
