I also have a 5X8 utility trailer with ST205/75R/15 tire wheel/tire the rim is 6inch wide steel rim. With a 5 on 4.5 bolt pattern on 1/2 studs. How much torque do I need?

I have attached a chart you can check out that describes the torque needed per wheel size, wheel stud size and material.

For an 8-inch wheel with a 1/2-inch wheel stud the torque is 75 to 86 ft-lbs.

For a 15 inch steel wheel with 1/2 inch wheel studs the torque is 90 to 120 ft-lbs and if you have an aluminum wheel the torque needed is 90 to 100 ft-lbs.

If you do not have a torque wrench I recommend the Powerbuilt Dual Drive Torque Wrench, part # ALL944001. This has 3/8 and 1/2 inch drive and will measure torque readings between 10 and 150 lbs.
