You have to go by the capacity of the axle even if the wheels and tires are rated for more weight. The opposite is also true, if the wheels are rated lower than the axle you have to go by their capacity. You always have to go by the lowest rated component in the system. To be able to carry more weight you would have to replace the axle and use wheels and tires rated the same as the new axle.

The highest capacity 4.80-12 tire we carry is a load range C that has a max capacity of 990 pounds, # AM10062. A pair of these on an axle will give you a 1,980 pound capacity. I have included a link to our tire FAQ article for you.
