I just installed Rota Subzeros on my 2k.
When I drive, it makes a horrible thud, thud, thud noise.
What the heck?

 

Also, any advice on fixing a stripped lug?
The numb-nuts that I bought the wheels from sent the wrong sized nuts.

 

What size are they? Sounds like they could either be too big or one of them could be bent.

 

A severly scalloped tire can make a thud-thud sound while driving (the pitch would change with your speed, gradually going away as you got to a certain speed). Can't say for certain that is your problem but changing your wheel may have made the issue more pronounced.

 

1 of your rims sounds bent by the way the problem goes away when you go fast. TAKE THEM BACK!
