Hi all. I just bought a 12' Smokercraft on a Caulkins trailer. It's a '98 boat and '99 trailer, neither of which have ever been in the water due to previous owner's health issues.
I will be replacing the tires on it due to their age as I will be trailering about 150 miles at Interstate speeds. The existing are 4.80-12 load range B, max inflation of 60 psi. It's my first boat trailer, so of course those tires look puny. My question: is there any benefit to using load range C in this size tire? Load range C calls for 90 psi which would seem awfully bouncy for this light a load.
The boat and trailer combined only weigh 400 pounds. My 9.8 outboard, fuel tank, electric trolling motor and battery, and associated gear could add around 225 pounds additional weight - still a pretty light rig.
Would load range B be the softer, more appropriate tire? If there is benefit to Load range C, would a lower psi be a problem? Nobody wants to be along side the interstate changing a tire, which is why I ask. I appreciate the input.
