Going with a tire that has more weight capacity will give you more tire capacity but the tires are only one factor in determining the overall capacity of a trailer. You also have to factor in axle rating, brake rating, frame rating, bed rating, coupler rating etc.

If your tires happened to be the weakest link in the combination then yes going with a higher rated tire will give you additional capacity.

The highest rated tire we offer similar to your LT145/R12 is the part # AM10140 which is a ST145/R12 that has a capacity of 1,520 lbs at 80 psi.
