Would Load Range B 4.80-12 Tire Have Enough Capacity for 1330 lb Boat/Trailer


Is load Range B with a 4.80x12 wheel on a boat trailer with a 1330 curb weight permissable


Expert Reply:

A 4.80-12 Wheel/Tire combo like # AM30580 would provide a 4.80-12 Load Range B tire on a 12x4 white spoke wheel with a 5 on 4-1/2 inch bolt pattern. The tire has a 785 lb per tire/1570 per axle capacity. If the fully loaded weight of your trailer is under 1570 lbs, you'll be fine with a load range B tire.

This being said, the price differential between the Load Range B # AM30580 and the Load Range C # AM30660 is miniscule. The load range C would offer a 990 lb per tire/1980 lb per axle capacity, there really wouldn't be any good reason not to go with the higher load range, as it's pretty common for folks not to include the weight of the gear stowed in a boat like coolers, fishing equipment etc. There would be noting wrong with having a little extra capacity to provide some 'wiggle room' in the common occurrence that there's more weight on the boat and trailer than you realize.
