I'm getting ready to take the boat and trailer to the Carolinas and back, about 1400 miles and would like any input on what I may be in for with this small wheel and tire sizes. The trailer is 2 yrs and the tires have maybe 300 miles on them w/no weather checking. I,have just cleaned end repacked the w/bearings and installed new inner seals. It also has bearing buddies... Any advice what I should take w/me as in spare parts???
