Did a search but did not find anything.

Wife scraped the right front wheel and tire on the curb while parking. The rim was scraped pretty bad, and the tire has a gouge taken out of it. I've ordered a new rim and tire and will have them installed this weekend.

Question: What is the proper torque setting for the lugnuts on the wheel?

Many thanks in advance for the responses.

it's until the airgun the shop uses stops turning.
I have never heard of anyone using an exact torque measurement
to put on lug nuts

A specific torque setting is common on many new cars. For example, my Lincoln requires the lugs to be tightened to 100 ft-lbs. Failure to tighten the lugs to the proper tightness can result in improper brake wear, among other problems.

I have not changed the tires before.

Are you kidding? Going by feel is not a serious option.

This might help. Looks like 75 ft-lbs.

most japanese car today require est. 80 lbs of torque. One might argue that it's 75 or 85. Average around 80. Older bmw and most suburu takes about 65 but some of new one is not 80 as well. I don't know what is the spec for the new IS. You can call dealer for that info.

I saw it in the owner's manual somewhere. I believe it's 76 ft.lbs.

yeah it's in the owner's manual... i remember it was some random looking number. 74 or 76...

i know that americas/discount tires torque the lug nuts.

Unless I know that the shop used a torque wrench, I always retorque them as soon as I bring the car home. I'm convinced that having all lugs equally torqued dramatically reduced the incidence of brake rotor warping.

Agree. I'm kind of surprised with some of the responses above. I don't think anything that has to do with the brakes, wheels/tires, etc., should be left to chance. I got a nice click-type torque wrench, had it re-calibrated and I'll re-check everything if the wheels have to come off for some reason.

I guess you've never talked to anyone that properly maintains and cares for their car I always use a torque wrench, and insist that dealers and tire installers do the same.

Even if the tire place uses a torque wrench, you should have them re-torqued after a few hundred miles just to make sure.

Not too sure about torque numbers but I think its between 74-80lbs. I usually torque my first gen to 80lbs and retorque again after a few hundred miles.

All,

Thanks for the input. I will check the Owner's Manual to be sure of the correct value.

Absolutely correct. I always loosen and retorque them after getting the car home, then re-torque again in a few hundred miles.
