If you're talking about lugnuts it mght be in your user manual. But most people just tighten them down like...

Twist all the nuts on then use the air tool to tighten them down so they're very loosely tightened(in a star pattern). Then do the star pattern again tightening each one for 2 seconds. repeat once and if your truck is on a lift or the tires are off the ground(wait they have to be off hte ground...) hit the sides of your tires just to make sure they aren't loose somehow.
If you really want the torque specs and no one knows just search the internet.

i wouldnt use air tools on aluminum wheels, its a good way to damage them. the torque specs for ANY bolt that contact aluminum is much lower than say on a steel wheel. some one here should have a service manual that will tell what exactly you need on an aluminum wheel. im going to edit your title some to clarify

Good point didn't realize he was talking about aluminum wheels. I wouldn't worry still though, just don't keep on tightening down the lug nuts to the point in 6 months they'll be stuck on. Torque tightening is the best, if you actually have a torque wrench.

It's 100 lb-ft. In your owner's manual.

My 03 owner's manual says 100 lb-ft on page 166. In the section about changing tires.

yeah, its 100 ft/lbs of torque it doesnt matter what kind of wheel you have, does matter what size wheel you have, doesnt matter if youre 4x4 or not. im pretty sure ALL rangers and explorers (or at least 90 and up) and pretty much any for 5 lug bolt pattern is 100 ft/lbs of torque. it depends on the angle of the acorn lug, the pitch of the stud, and the thickness of the stud and obviously ford uses the same studs in MANY different applications.

a rule of thumb that i kind of have is with lug nut studs, is that for every number of studs there are, you can add 20 ft/lbs. so lets say 4 lug, would be 80 ft/lbs, 5 lug, 100ft/lbs. and if youre off 5-10 ft lbs, chances are that you cant even notice with a torque stick cause theyre arent EXETREMELY accurate.

and with german cars with bolts intstead of studs itll be either 89-90 on cars and 90-100 on SUVs and vans.

saturns with bolts will be 100 ft/lbs.

Look in the section called "Roadside Emergencies" and page through the section on changing a tire. I found it in about a minute.

so do the heavy duty trucks with 6 or 8 lugs....are they torqued to 120 and 140?

torqueing them is cool..u could roll O.G. and just tighten them down with the wrench and socket till it wont turn anymore

i didnt think torqueing(sp) them didnt matter that much. ive always spun the tire iron on the lug until it stops and then give it a bit more twist and thats never failed.

thats just my rule of thumb for most cars/ passenser vehicles and light trucks, but depends on the truck you are toqueing.

a few examples:
ford super duties: usually 160 ft/lbs.
ford 150s with 14mm studs, 150, with 12 mm studs, 100
dodge dakotas and 1500s, 110
new dodge 2500s and up 135,
pretty much all chevy 6 lugs, 140.



and then you have the crapper cars. aka ford festivas, geo metros.

usually those are only like 55 ft lbs.

100 is what you need to torque them at

i work at costco in the tire center and i have to say that we are the only place that i know of that actually torques the lug nuts. we leave are guns at level 2 and lightly put them on and then torque them. a lot of shops will leave their guns at like 5 and hammer them on, this is bad because they are overtorqueing them.

just because it is 5 lug doesn't mean that it is 100lb. cars tend to run around the 70's and 80's and super dutys are up in the 140's. though supergildo's idea is close on some cars it will not be perfect. if you have a question on a specific vehicle then let me know and i will try to find out the torque for you.

I work at discount tires and have worked there for quite the long time and previous to that worked at Big O tires for quite a long time, we also torque our vehicles after hittting the lugs on with torque sticks.


this I dea is a rule of thumb. somthing I use for cars the have no guide for torque on the charts. and its also just an idea of what certain cars should be at a certain range.

Gil sorry if i sounded a little rude! i didn't mean to sound that way.

I am very happy to see that you also torque your vehicles, if the cars that you get in are anything like mine then you have to know how many lugs are over-torqued!

most people dont know how to use a torque wrench properly, ESPECIALLY when they try to hurry. so yes i agree most cars are overtorqued.
