lug nut torque?
 

1999 F250 Superduty 4x4 5.4liter
I read somewhere in this forum that wheel lug nuts should be torqued from 150 -165 ft. lbs. Does this include alloy wheels? Thanks in advance for any insight.

I believe this would be too much for alloys, I have Micky Thomson II's and do 125lbs. No problems.

I should have specified that these are FORD alloy wheels that came from the factory when I ordered my truck thru the dealership.

I don't torque my wheels. I think a 300lb compressor with the impact gets them on tight enough ;-)

i have 2005 F350 manual says 150 lbs have alloy wheels.

Dude,
That's a great way to warp your brake rotors...you might want to re-think that strategy.

150 ft. lbs is about right, even for factory alloys.

gw

that could be why when I got the truck those front rotors were SHOT. I was scared to step on the brake.

150 lbs ft

The torque that is stamped on my lugs that came from Alcoa for my Alcoas is 140 lbs.

Go read the thread from a few weeks ago where a Super Duty owner was towing a trailer across the Bay Bridge in San Fransisco and all his lugs sheared off of a rear wheel. He lost a wheel, he suspects because he rotated his own tires and overtightened the lug nuts.

He managed to get the truck and trailer off of the bridge without hitting anyone or anything, not sure how but he did.

its stamped on my lugnuts 150 with factory alloys

From the factory service manuals for 2000-2007 the spec is: 8-Lug M14 wheel bolts 224Nm or 165lb-ft for alloy or steel. You do have to use the correct lugnut type for each type of wheel of course. By the way, over torquing is very bad - 'bout garantied to have a bolt shear at some point. Over-torqued lug bolts should be replaced ASAP.

Please forgive me for jumping in this thread, but Hey, now got some answers for a thread I started a few weeks ago, but now,,, is there a difference in lug nuts for each factory type of wheels on an 07? Will the steel factory lug nuts not work on the factory alloys? I did it on mine - do I need new ones?

Thanks!

the tire place told me 1150 lbs for my alloy wheels

Not positive on the steel vs alloy lug nut being different on all models / years. I do know that on most of the SD model years they are in fact different. The ones for alloy have an integral washer whlie the steel don't. Do NOT use the wrong ones. They will not work properly and are dangerous if used on the wrong wheel type.

jake00 - If yours are stock alloy wheels they should be 165lbs according to the book. Check with a ford service center to be safe.
