VimRC tabwidth set overwritten

Here is my vimrc configuration:

set tabstop=4 softtabstop=0 expandtab shiftwidth=4 smarttab

execute pathogen#infect()
syntax on
filetype plugin indent on
colorscheme spacegray

The pathogen vim overwrites my setting of tab. When I disabled the pathogen, the tab and spaces in vim works correctly. How do I fix this?
