I have a Palm Beach White Cap 161...its a 16ft center console on a magic tilt with 13" tires. I want to be able to pull it to either west or east coast and live in central florida. I need two new tires and dont know which to get. I am being told(by the tire company) that the overall life and ride will be better with the radial. They cost twice as much though...and the boat isnt all that heavy, so I dont know how the ride could be different. I could just go to walmart and get some bias for about 130 and be done with it. Discount tire quoted me 313 for two radials with wheels balanced. If it is truly worth the extra money I dont mind spending it. I pull the boat with a Hemi Durango(dont know if the vehicle makes a difference). I get the boat out twice a month...3 times if Im lucky and do salt and fresh. Any advice would be great thanks.
