Pizza Pan covers over 16" GM alloy OEM wheels

[WesternStarSCR]

Ahh... not yet Metro... plan is this next month or 2, I need to rotate the tires anyway.

The guys at work use these now on the aero package equipped test Freightliner Cascadias:

Deflecktor | Aerodynamic Wheel Covers | Tractor Trailer Wheel Covers


So maybe 0.25% better FE per wheel for me too, once I do this...

Settled on the order of the assembly of the stud:

Backside of wheel, working way out:

1. 2" long screw threaded from backside with loctite
2. External ring washer
3. Wheel (thickness TBD)
4. Retaining washer
5. Fender Washer
6. Grommet / Pizza pan
7. Fender washer
8. Retaining washer
9. Locknut

The retaining washer / fender washer combos give a bit of a bushing effect to the pizza pan, so I can snug it all down and not worry about binding or tearing the grommets against the wheel.
