They are silver and include the following:

Four new unused rims in the original Chevrolet OEM Boxes.

Four matching new and unused OEM center caps. Value $150.00

Four GM OEM TPMS Sensors already attached to the rims.Value $150.00

A set of new and unused GM OEM lug nuts that come with the set. Value $150.00

Chevrolet delivers the new C8's with these rims and the dealership swaps out the rims to black rims, that are on the specification sheet. So they were on my C8 when it arrived at the dealership, but not when I took delivery.

I have no idea why they did it that way, but they do.

Shipping is very expensive and the boxes weigh 30 lb.s and 40 lb.s, front and rear are different sizes see below. 

The boxes measure 22x22x11 and 25x25x13 accordingly.

The front rims are 19" and 8.5 wide  The rear rims are 20" and 11" wide  They have a bolt pattern of 5x120.65
