Driving with 4 out of 5 studs

Re: Driving with 4 out of 5 studs

How many people actually look up the torque specs for their wheels?

Well....I do!

I just related my personal experience with a failure. Did I happen to get the bad batch of lugs that along with an over torque condition cause a failure...maybe. Would this happen to you if you did it. Obviously won't happen all the time.

Not sure where you come up with the lubed vs unlubed being only 80%. Guess it is the engineer in me that want to know the actual numbers. Check out the following calculator.

The lubed spec is less than half of the unlubed spec.

Read this article for how important it is to use proper torque:

I read a hardware distributor's spec sheet at one point. Lubed vs. unlubed specs for torque were given. I divided the two numbers for a lot of sizes and found the two methods varied by an average difference of about 20-25% less. Felt pretty good about it ever since.
