I had some of those years ago, (60's) I used the factory torque # for car or for stud dia. never had a problem. Back then and now, drive car short distance and re torque wheels, Make sure everything looks good regarding condition of threads, nuts, seat, etc. I always use a little never cease, back then a touch of grease. The fact it's an aluminium wheel has no factor on torque # IMO.

 

When you mount unilug wheels on the car, keep the lug nuts a bit loose, rotate the tires as you slightly cinch them down. This keeps them centered. Learned this on a set of 15X12 Cragars.

 

If you gave us a little more to go on....like a picture of the center of the wheel, so we can see the lug nut holes, and also a picture of the nuts and washers you are using.

I torque "mag" shank type nuts on aluminum wheels to about 70 if they are 7/16" studs, and 90 if they are 1/2" studs. As long as they're tight, they don't come loose. The suggestion to torque them more than once, is a good one. I re torque after the first short drive, and again, every now and then.

 

I have noticed, in my can of used mag lug nut washers, that many are badly squished or cupped. Some are also thicker and larger in diameter than others. So I would say that with unilug wheels quality washers are important.

***ume you are talking about standard type unilugs, not ETs etc.

 

On my car, the aluminum slots are unilug. Some of the wheels only had 2 unilug washers and the rest were round! Presently I am changing it to steel smoothies and that problem will be solved. I had not noticed until I removed a wheel to try one of the smoothies. Luckily I didn't lose a wheel while driving it...

 

I had them on my Camaro in the early 80's. I used regular mag wheel nuts and washers. Didn't know any better, but made several trips back and forth from Phoenix to Sacramento without an issue.

I seem to recall seeing oblong looking washers for them hanging on AP store shelves though.

 

Thanks
