I just got Winter tires for my 2010 Corolla and my local tire shop put them on Pacer 15" 83B-5618 rims, but my Toyota wheel covers don't fit. Amazon thinks these are not "correct" for my car but the Pacer 83B-5627 is correct. Both are 15", 41mm offset and 5.13" backspace. I was wondering what the difference was, maybe 5627's would hold my wheelcovers? If not, just what is the difference, does anyone know? I tried the Pacer website, but only got a cascade of errors.
