Yes, the Q7E is the same size and looks the same as Q7S, which is the standard silver 5-split spoke aluminum wheels on the standard Z51-optioned cars. QX3 are the smaller wheels and are not split spoke.

Wheels, 5-spoke, chrome aluminum, 18" x 8.5" front and 19" x 10.0" rear
Q7E =
Wheels, chrome aluminum, 19" x 8.5" front and 20" x 10" rear
