vapor liner kit
 
This thin nylon vapor liner protects white and light-colored vinyl tire covers from getting soiled from a dirty tire.  This is also thought to prevent the dye in new tires from migrating into the tire cover. 
 
This liner will absolutely make installing your tire cover easier.
 
Configurations:
  If you have a Bronco with a rearview camera, order the vapor liner with a grommets. The vapor liner will have a hole in the center and will include TWO grommets.
 
If you have any other vehicle with a rearview camera, such as the Jeep Wrangler, you will not need the grommet, so order the liner with a camera portal.
 
If your vehicle is pre-camera, please order the stand-alone vapor liner with no camera portal and no grommets.
