Dec 6, 1967 my Chrysler 300 convertible came off the assembly line. To celebrate, took the ride for a new pair of shoes(tires). Replaced the 14 year old Coker bias ply( 4 1/2 inch white walls) with Cooper Trendsetter radials with closer to correct white walls. 235 75R.15. Wanted to change to Magnum 500 wheels too, but got other fish to fry this month, so it will have to wait till spring. These are the before and after photos.
