Hi all, I have a 1954 Plymouth Cranbrook P25 series that was built in Adelaide South Australia. It was fully restored when I acquired it & has 16" x 6" wheels and cross-ply tires. Now that the historic registration rules have been relaxed I want to get 15" wheels to fit so I can put radials on to improve the ride & handling (the only 16x6 radials I can get here are light truck tires). I need advice on what 15" wheels I can get that will fit the stud pattern and would be readily available in Adelaide. Second hand would do. Thanks, Bob.
