They're called "rail caps"....sometimes "roof rail caps". Search on either of them, you'll find many references.
For reference, they used to sell for over $200 -$300 for a set of 4, then a few in the $100+ range, then recently a few for $70-$75. Some have carefully modded them to fit WITH the roof rack towers in place. VT_Mav made an extra set which I bought.

This guy has some for sale, not sure if they're sold or not:

There's tons of threads with detailed wheel/tire fitment, backspacing etc, etc, etc, info.
The OEMs are +38

One is to replace one or more of the plastic roof-rack fillers. These are the fillers that sit in the roof rail when a rack is NOT installed. Got any leads on best location/price for these parts? I couldn't even find a single reference to what they're called while running a search on this forum!

Shoot me a PM with the positions you need, I have several extra caps in the toolshed at home. Could also make you a set of those custom covers if you like - do you already have the cross bars?
