I believe there are 3 wheels available for the Laramie Longhorn, 2 - 20" and 1 - 22". The color on the 20" depend on whether it is monotone or two tone. The 22" looks grayish.
Don't know 100%, but it appears that way from the 2019 ebrochure, although it looks like the colors are reversed based on personal experience.
I don't think it is Max Steel as that looks black without the sun hitting it. I tend to go with the granite color.
