Where to find torque specs for lug nuts?

I debated replying to ‘Sears broken bolt’ but didn’t want to hijack that thread. That thread made me curious though. I have to make a 350mi trip soon. Where do I find the torque specs in case of a blowout?? I looked everywhere in the manual(s). I built/bought my own full sized spare/tire. Also, what’s the BEST way to change a wheel when on the road?? I’ve ridden in a car that had too loose lug nuts…They ended up replacing the windshield in the car behind them. Thanks.

Owner’s manual. ( It’s in my Ford ones )

It is usually in the owners manual under specifications, most cars with the aluminum wheels are 75 - 80 ft lbs. Can use the same or slightly more for steel. My Toyota spec is 76 ftlbs. not sure what you mean by best way to change a wheel, get WAY away from traffic so some drunk doesn’t pick you off.

Yup. The manual.
The Subaru manual provides torque specs, just like Ford, Toyota, etc.
IIRC, in the Subaru manual it is listed in the section on changing a flat tire, rather than in the specs at the back of the manual.

On both my cars, Toyota and Nissan, the torque figure is in the OWNER’S MANUAL in a section called “Specifications”

Thanks everybody…found it to be 80 lb/ft. Only after looking under specifications as was suggested to me.

Are you going to carry a torque wrench in your car. Just in case any one needs a refresher on tightening patterns, I usually do it 3 times starting with contact, then snug, then tighten, enlighten us if you have a better way! (comments?)

If you have to change a tire on the side of the road, you use the tools that come with the vehicle. Most of the OEM lug wrenches are too short to allow most people to over torque the wheel. Just get as tight as possible. Then, when the tire is repaired/replaced, get it torqued properly.

If you do own a torque wrench, it is only accurate when moving. Its best to get each lug nut tight enough to be centered in the hole. When all are centered and snug, put about 25 ft-lbs of torque on each, then go to recommended torque in one smooth motion.
