most alloy rims spec about ~75 ft/lb per lug nut, if you go higher you will end up stripping the threading.
Oh my. This illustrates the danger of knowing enough to be dangerous. So many internet experts.
Torque is a rotational force that is described by radius to which the force is applied and the force at that radius. So if you are applying 75lbs of force at one foot the equation would be 75lbs X 1 ft = 75 lbs·ft. Because no units cancel each other out, they have to come across, as lbs·ft. So it's
not 75 pounds per foot (75 ft/lb), it's 75 pound feet (75 lbs·ft).
Second, you probably were using a torque wrench that was longer than 12 inches and calibrated accordingly. Meaning the force you exerted was much less.
Third, most wheel studs on modern cars are SAE grade 8 or ISO 10.9 studs, meaning they are carbon alloy steel and have a tensile strength of 150,000 pounds. You are not going to strip or break one that's in good shape without WAY overshooting the torque specs.
Ironically, why alloy wheels have a lower torque spec is actually related to the topic at hand. By alloy wheels they mean an aluminum alloy. So the wheels are much softer than steel wheels, and therefore cannot be torqued as tightly without damaging the wheels.
Well, it depends on the design too (also related to the topic!). Different alloys and mechanical design also affect the torque spec. My truck has aluminum alloy rims and torques at 150 lbs·ft. I'm not sure what the specific alloy is, but suffice it to say it's not as soft as some others. Also, it is a hub-centric wheel, so the lug nuts are flat, not tapered. This allows the wheel to accept more torque as well.
I wouldn't have picked on you, except that you used your marginal knowledge of another subject to try and ridicule those that are concerned about the potential (not sure I am convinced yet) of the iPhone 6(+) to bend, by the absurd claim that the force to bend an iPhone was the same that holds your tires on.
Back to our regularly scheduled program of iPhones can't bend because people don't kick cars intentionally or something...
