Hi, I found a pretty good '67 VW and need new tires. It has 5.60X15
now. I see about three common sizes of radials: 165X15, 155X15, and
145X15. Which is closest to my tire size? I like the original look of
the 5.60s and don't want tires which look too big (diameter and/or
section) but can't afford the price for 'classic' tires.
