Wheel lug torque specs

[LUDELVR]

Have aftermarket wheels but more importantly, aftermarket lugs. Do these require the same amount as the stock lugs or should they be different because of the material?

That's a fairly vague question my friend.
The biggest factor is materials. What are the lugs, wheels and nuts made from?
Then what is the interference type? Concial? Ball? Shanked?
Bolt pattern? I know your not running centre lugs, but those bad boys are like 350 ft/lb!

In most cases your likely to strip the lug first so using the stock torque number is probably best. If in doubt i just run 75 and check them every once and while. If you plan on tracking your car, most tracks require 90 ft. lbs.

Haha sorry. Wasn't even thinking when I posted. These lugs came with the car and I think they're those rays tuner lugs made out of aluminum and I'm pretty sure they are conical. They are just replacement ones but I just don't want to overtighten them.

When I worked in the tire shop, generally cars were 80-100, SUV 100, Trucks 120+ depending on the size of truck.
Aftermarket rims or steelies. Unless specially requested or it was a weird set up. That's why you are supposed to check them after 100-150KM, make sure that they are still good

On the back of my Muteki package, it shows 75-85ft lbs for torque spec.

Mystery solved. Really so long as its in the right range and stays there call it good.

That is true... never use grease or any lubricant. If you do, it will over-tighten the nut using the dry torque spec.

I usually just tighten everything to 100~105ft-lbs for cars, and about 110~120 for trucks. Even the best torque wrenches are not as accurate as people like to think, I'd rather slightly over-tighten (as bolts have a massive safety factor) than under-tighten and risk losing a wheel in traffic.
I snapped a lug off a toyota corolla once. I wasn't really paying attention, and I was used to dealing with heavier trucks at the time. Wasn't using a torque wrench, but wasn't really givin'er. Snapped one stud, and stretched/yielded a couple others.
Turns out the torque spec on that was something like 80 ft-lbs, and I was probably 120 or so with my finely calibrated biceps. I also had anti-seize on them, which was making it worse.
Boy the owner of that corolla was pissed! I don't get asked to swap them over to winters any more, so win for me! :thumbsup:
