Is that from the owner’s manual?.......arn:

LOL... now that is a blast from the past!! I love that movie!
Loosen the nuts and retorque them yourself.
The manual does say 80ft-lb for all the tires.

Maybe check your owners manual again... carefully.
For the record.. the correct answer is 80 ft-lb. Probably more important that they all be at the same torque more so than the actual torque value... as long as you get it to 80 so you don't have a wheel working it's way loose on the lugs over time.
Personally, I always check and retorque to 80 ft-lbs a week after any service that involved removing the wheels. Better safe than sorry.
Yeah, the reason I asked in the first place is that the latest manual only addressed torque fir the steel spar, not the alloy wheels. So, …, talked to the guy that does our mandatory PA state inspections and let him know that my wrench shows 125 ft-lb. I have an an appointment in the morning for him to see why the torque is so high. I’ll have a Bloody Mary first. CheersMaybe check your owners manual again... carefully.

When in school I thought I was taught it (torque) was "ft-lbs" Now I see it mostly mentioned as "lb-ft"..except in this thread.
OK, I looked it up. LOL
The “pound-foot” (lb-ft) is a unit of torque and a vector measurement that is created by one pound of force acting on a one foot lever. The formula for torque in the instance of tightening a fastener would be: Torque equals force times radius, or T=FR. When tightening a bolt, “R” would be the length of your wrench.
The “foot-pound” (or more accurately, “foot-pound-force”), on the other hand, is a measurement of work. Work is the measurement of force over a given distance. So one foot-pound-force (ft-lbf or just ft-lb) is the energy required to move a one pound object one foot of linear distance.

There are two steps here. 1) how to create an objective unit of measure. 2) how to apply a unit of measure to work performed. The first is very clinical and objective in establishing a unit of measure. The second generally results in such units of measure to be used in novel ways beyond why they were created.When in school I thought I was taught it (torque) was "ft-lbs" Now I see it mostly mentioned as "lb-ft"..except in this thread.

I guess lb-ft and ft-lb are essentially interchangeable in application as a metric. Both correct, for the purposes of the pragmatics of tight lug nuts, but on a class test.. gotta go with what the professor declares.
My torque wrench has triple metrics ft-lbs, newton meters, and inch-lbs on it's dial to set the torque limit.So applying a torque wrench to a lug nut is indeed applying "measurement of work" as the meter on the wrench tells you how much force you have applied to a lug as it tightens to the wheel. So, ft-lb would be correct in my view and most logical for the task of using a torque wrench.
Or we could shift to newton meters which is an actual measurement of torque force, and follows the same convention as lb-ft (force on a lever for a specified distance)
My wife would tell you that she simply sets the wrench to 80, tightens the bolt until the "thingy" which is set to 80 clicks, and completely bypasses all the ambiguity of technical terms.
Yes... she carries a breaker bar and a torque wrench in her trunk kit and knows how to use them.. though she always seems to have someone close at hand ready and willing to change a tire for her (most often ME). 1 - 18 of 18 Posts
