Does anyone know the thread pitch & size of the rear lug nuts on a 300ex.Also I just put new wheels on the rear & the lug nuts are beveled,but the wheels are not.does everone just put the lug nuts on backwards or should I put the on the way they came stock.Thanks for any help.

 

I don't know about the threads but you should always turn the lugs around on aftermarket wheels. If you don't the lugs will "dig into" the wheel and they will be a pain to remove.

 

On aftermarket wheels it's also a good idea to use a flat washers. It keeps the nuts from tearing up your wheels.

 

TURN THEM AROUND AND RUN THEM BACKWARDS!!!

if you run them the way they are in the stock rims they will not just be hard to remove, but they will completly destroy the rims!
