Hi i wanted to know the correct torque spec for my new trailer tires. I used a 3/4 socket to tighten the bolts to 60ft lbs. Is that enough

The correct torque value would depend on the diameter of the wheel stud (not the wrench size needed to remove the lug nut or bolt).

• 7/16 inch stud- 55-65 ft-lbs
• 1/2 inch stud 75-78 ft-lbs
• 9/16 inch stud 95-115 ft-lbs

These torque values hold true for steel wheels that are between 8-14 inches in diameter.

A wheel meant for the 4.80 x 8 tire would use a 1/2 inch wheel stud, so you'd want to go up to at least another 15 ft-lbs.

I've linked to a series of articles with tons of information about trailer wheels and tires.
