The correct torque for installing lug nuts on your 5 X 8 trailer's 5-lug wheels will depend on the size of the lugs. For a 1/2-inch lug the torque spec ranges from 75- to 85-ft-lbs. For a 9/16-inch lug the torque spec ranges from 135- to 145-ft-lbs. Please refer to the linked chart.

You will want to avoid using an impact wrench or any other tool that cannot provide measured force. Use a torque wrench for accurate results. You should re-torque them at 10 miles, 25 miles, and 50 miles, and then periodically after that.

The closest option we have to those specs is the Kodiak # KALN1375S. This 1/2"-20 wheel lug nut features a 13/16" diameter and overall length of 1-9/16".
