Mazda6 andCadillad Seville

Ok trying to figure something out, I just talked to a guy that I might trade wheels with I have a mazda 6 with 5on4.5 lug pattern and have brazen br530wheels and he has a caddy seville with some lexani iris wheels and we are not sure if they will fit on mine and mine on his both wheels have dual lug patterns, does anybody know if they will work or not, sorry for the confusion just trying to figure it out

mazdas, nissans,mitsus/d50s, and what not are 6 on 5.5

what year seville? the newer ones are 5x115 i think and the older ones are 5x120.7 (5x4.75)

a lot off the dual pattern wheels with 5x114.3 (5x4.5) also have 5x120.7 (5x120.7) those are common sizes

hope that helps

his is a 92 seville, so i guess his is 5on11.5 and mine wouldnt work then? that right? What would his dual lug wheels be then?
