Thanks for the photos, they help me visualize the wheels a lot better.
Just so I'm clear, I'd order a set of these (the greys), some new center caps from my local SC (and maybe a set of Gorilla 61147CX lug nuts), then take the whole lot down to my local tire place (Discount Tire) and have them pop the tires off the old 19"s, switch everything over (including TPMS sensors), and I'd be done? Anyone know what the typical cost is for that kind of swap out?
