bought a new impact gun and would like to rotate my tires. I need to hand torque the lugs after i put the rims on, any idea as to how much?

Also make sure you put some lube on the threads. It will increase the torque by a small percent (3 to 8) but it will not harm the threads (cross threading etc).

Lastly, try to install in the cross pattern. If there are 5 lugs: tighten lug at 2 (o'clock position) to 7, then to 12, then to 4 then to 10.

If not, do not worry that much.

Agree with completely :cheers:

Also, I set torque to 65 ft. lbs for FIRST STAR PATTERN, then I up it to 76 ft. lbs. and star pattern again :D

Some lubes have a certain values it increases. I have a list at work, from Mark’s Standard Handbook for Engineers (Bible in engineering world), named many lubes with their respective base material. Like some are moly based, silicone, alum-oxide, etc.

To sum it up, each lube lowers the coefficient of friction. So by lowering the friction it will increase the torque for that thread. As long as you do not yield the bolt/stud you are fine. Do not worry it will take a lot to cross-thread the bolt. You can figure it (cross-threading) out with some basic formula but no need to.

The only formula I remember is: T=(K)(F)(D)

T=torque (ft-lb, N-m whatever units you have)

K=torque coefficient or nut factor (Lube chart)

F=Nut load or clamp force

D=nominal DIA of bolt (in, ft, m)

I use anti-sneeze J (seize) on my lugs; however, you can use engine oil, chain lube etc. Anything is better then nothing. Just try to remember the torque formula in case you torque to max, which is perfectly fine, and add a certain lube. It will case the torque to go over you max. Just be aware.

I sure hope nobody followed this advice for adding lube to the studs. What can require 55 ft-lb torque dry, only needs 30 ft-lb lubed. This is at least 80% over torqued condition. You can seriously over stress the threads and the studs and/or nuts will fail! The torqued values given are from the manufacturer are for dry conditions. Do not modify this for your own safety. Two degrees in Mechanical Engineering and a career in machine designing gives me the qualifications for these statements.
