Do you tighten your 8 lug wheel nuts to 118 ft.lbs?

    118 ft.lbs is what Haynes says is right for the wheel nuts on 8-lug wheels (9/16 studs). This seems overly tight - what do you guys run them at? My tires are only an embarrasing 31" tall (not for long tho!) so it's not like the mass of 44's has to be restrained.

    My Weld wheels had a sticker on them when I got them new and they require a 125 ft. lbs. spec.

    Man, I just tighten them real tight and give it another 1/4 turn. I can't imagine taking out the torque wrench for 32 big a$$ nuts.
    The studs actually stretch when you torque them and if you overtorque them they can stretch till they break. It can happen. If it does, buy a new one and don't tighten them quite as tight next time.
    Don't make it more complicated than it is.

    I hear you man! Eveyone is just covering their butts these days.

    Anyone know the correct torque for the gas cap on an 82 K3500 .... passenger side?

    I was always told that if you over tighten aluminum wheels they can crack... Is this not true?

    I thought my chiltons specified 105 for 8 lug & 90 for 6 lug - that's how I torque my 2 k5's (and yes I do torque them), and haven't had a drop of problems to this date.

    Ken, there is a reason you torq your lug nuts........ It's so you will not warp your brake rotors!

    jwduke is right.

    However, I think 140 is on the high side!

    You definately should not exceed what the wheel mfg specifies

    I crank them until I can't get them any tighter. Screw torquing anythign that isn't inside a motor.

    If you can figure out how to warp such monstrosities as my rotors, be my guest. You'll break the wheel studs first.

    I have never used a torque wrenh to put on my wheels. On any of my vehicles. And now I use the impact. I dont go back and cehck them. Man, if I checked the torque on every thing I tightened, I would never get anythign done. I agree some things are important.

    Warp your rotors from tightening the lugs too much. Thats new to me. I could see how it would be possible, but come on.

    Some people are so anal on stuff.

    What is the correct torque for my gas cap?

    Tim, I think the torquing of lug nuts is intended for the bozo's at the tire store & their 1,600 ft. lb. torq impact wrenches. I figure if you can tighten it up to where you can remove it again with the tools that Chevy sent you,with your truck, you are ok.

    Technically speaking, yes, you can over tighten your lug nuts. 100-125 is perfectly acceptable. You have to remember that on our trucks, the lug nuts are part of the brake rotor (well, connected to the brake rotor) while on many of the newer cars (most imported) the Studs are not part of the rotors (the rotor slides over the studs).

    I dont understand exactly why this makes a huge difference, but it does. When the studs are part of the brake rotor, over torquing and even torque variances between the bolts arent a huge deal. On the studs arent part of the rotor, over torquing and torque variances cause the rotor to warp.

    I never had a torquing issue until I started driving imported cars! So now, yes, I do use a torque wrench to finish off.
