What size tire do you need? Are the axles single or dual wheel? If you need size 215/75-17.5 then tire # TTWP15175 has the highest capacity. On single wheel axles it is rated for 4,805 pounds at 123 psi. On dual wheel axles it is rated for 4,540 pounds at 123 psi.

If the axles are single wheel (4 tires total) then the maximum capacity would be 19,220 pounds. But if the axles are dual wheel (8 tires) then the maximum capacity of the tires would be 36,320 pounds.
