airbrushguy Posted October 11, 2011 Share Posted October 11, 2011 First: what is the original 15" tire size for a 39 Buick Century? next: what is the right whitewall tire width? next: has anyone ever replaced the headlight bulbs with halogens and kept the original lenses and reflectors (converting to 12 volt)Last: how tall are the original tires?Thanks Link to comment Share on other sites More sharing options...
Guest Grant Magrath Posted October 11, 2011 Share Posted October 11, 2011 Pass to every question except the halogen one. I believe you can get 6v ones if neccessary.CheersGrant Link to comment Share on other sites More sharing options...
danhar1960 Posted October 11, 2011 Share Posted October 11, 2011 Rim size was 15"x5.5", tyre size was 15"x7.00" 4 ply. White walls are the subject of some discussion but I'd say 3-4" is about correct. I'm not sure that there was a standard on this. Each manufacturer probably did his own thing.I know of halogen lights being used in a '39 with a 12v system. It took a little fidgeting around but they worked fine. You just have to have the electrics to keep up with them.Danny Link to comment Share on other sites More sharing options...
Terry Stock Posted October 11, 2011 Share Posted October 11, 2011 Have 6v halogens. Fit just like normal. Link to comment Share on other sites More sharing options...
