While on temporary work assignment, in Tulsa, Oklahoma, I bought a used 14? aluminum semi-v boat with Merc 200 outboard. The trailer has the small 4.80 x 8 rims and tires with the 4 on 4 lug pattern. I plan to clean and repack all bearings and put 5.70 x 12 tires and rims on the trailer. I will be pulling the boat and trailer 630 miles to home when I leave Tulsa. Will the trailer be up too this kind of trip? I will be running about 55 to 60 mph.
