If I had 4 out of 5 lugnuts on my rear tires... what would happen? Anything bad?

 

nothing would happen...i wouldn't be doing too much drag racing but normal every day use wouldn't matter

 

I would think you would replace the missing lug nut.

 

Take some off the front wheels. The back ones are the ones that all the spinning.

 

It'll be fine. My friend raced w/ only 3 one one tire then again, he's not the brightest fellow. Another friend had only 2 lugs on one wheel on his integra (4 bolt pattern) and drove around like that for bout 2 months.

 

LOL and the front ones do the steering.

 

When i went in for a driver test, they require 4 out of 5 or 3 out of 4 lug nuts on each wheel or better of course. Right before my test i panicked because i knew they checked that and i noticed one was missing.

Why not get another set. autozone has em for a dollar each.

 

It will be fine aslong as you don't launch too hard, or drive on the highway any... Go buy a new set or something though.

 

If by bad you mean the wheel working loose and falling off; then yes.
We had a Ford half ton in our shop recently that required over $2000 worth of repair and body work because a rear wheel worked loose. Safety inspection here requires all wheel studs and nuts to be in place.
