Lug Nut Torque for a Trailer Wheel

Question

Question:

I have a 4300 lb trailer with ST 205/75R15 tires. The wheels have 5- 1/2inch lugs. I believe the sticker on the rim says 90-120 ft/lbs. Could you please confirm this, Thanks.

90-120 ft lbs of torque is probably about right for your trailer rims. If you check out the lug nut torque chart that I attached you will see that nearly all of the torque specs are that and higher.

Since you have leaf springs that are most likely the 25-1/4 inch length unworn out the best leaf spring replacement would be the part #e34SR which is for 6k trailer axles. Since you wanted a slightly over rated spring this would work great.

You can pretty easily go from a 205/75-14 to a 15 inch tire size like 205/75-15 like with the #AM32395 without clearance issues. This will give you a slightly larger wheel and tire which will have a higher weight capacity. So you might gain a slight…
