BTW the #1 cause of spark plug seizing is not tightening to proper torque! Why? If the seal doesn't crush, carbon fills the threads due to a small leak. You still should use anti-seize.
Toyota does not recommend anti-seize on their wheel studs, but I do it anyways. NEVER had a problem, but be sure you don't put anti-seize on the washer where it touches the wheel! Then they might fall off, and you overtorque (stretch) the crap out of them. I also have aftermarket crap nuts though, I'd leave the stock stuff dry.
Not pulling this out of my ass, I worked on Toyotas professionally for 5 years...
