New to forum and could not find newer posts for this subject. If one exists, would appreciate being pointed to it so I don't have to start a new thread needlessly.
The newly acquired '59 Skyliner's 800 x 14 tires are old and cracked and I have no idea if whitewall width is correct for the period. I definitely want radials and think I want bias look radial tires but would like your opinions. My questions are:

1)What source and brand is currently the best

2)Is 800R14 correct or is there a metric conversion size that matches it

3)What is the correct whitewall width. The car will not be judged, but I don't want a 1 inch stripe if 2 1/2 or 3 1/4" was correct

4)Are bias look radials the way to go or is there a technical downside to running those reproductions for appearance sake

5)Any other tips that I may be overlooking

Any and all advice based on your experience or opinion will be appreciated.

Thanks in advance, Bill
