no they are a 15 inch centre with a 15 inch outer...
you used to be able to get step down rims from roh to put 14 inch centre into a 15 inch outer..dont know that you can get them anymore..when pontiac started doing the 15 inch rally 2 rim there was a 1 year run of 14 inch centre to 15 outer and that was 1970..after that they were all 15 inch centres with 15 inch outers..dunno why they did this coz 69 models had 15 with 15...
