Veteran Posts: 236 Location: Morgan Hill, CA I need to find a replacement spare wheel for my 57 Fireflite convertible. Can anyone tell me what size it should be? The one in the trunk looks like a 14" x 6" but I've seen a references that indicate it should be a 14" x 6.5". Are the wheels the same as say a Chrysler or something else or are they Desoto specific? Thanks, Doug Edited by dlyle 2017-03-17 6:40 PM NM Desoto Posted 2017-03-17 4:44 PM (#536129 - in reply to #536121) Subject: RE: 57 Desoto Fireflite convertible wheel size? Veteran Posts: 145 The 14 X 6" is correct for your car. I think the 14 X 6.5" were only used on the letter cars, New Yorkers, and the big wagons. 57burb Posted 2017-03-19 9:25 PM (#536233 - in reply to #536129) Subject: RE: 57 Desoto Fireflite convertible wheel size?
