Hi Lisa, this gets discussed quite often and there are several differing opinions. For me and my '53 panel, I use Michelins, size is 215/85R16 with tubes. I have original riveted 4" rims. I had tried bias plies first and they were barely okay. When I planned a longer trip (2500 miles) I decided on the radials and will be keeping them. Some say not to use tubes but I haven't had problems.
