I can get 4 L78-15 Coker's from Summit for 688 shipped. From a search on here, a few years old, people werent too happy with their Coker tires and suggested diamond backs. Only problem is those tires are like 70 or 80 bucks more each. Going with the 4" white walls for my 1950 caddy 61 series. Currently it has some old dry rotted Uniroyal L78-15's on it. If I go to coker's website and search by year, make and model - they dont suggest the L78-15, but some other ones that have a lower weight rating and cost more. What do you guys think?
