Awesome Doug! Thanks!
For me, all I care about is that they have more concaveness than the stock rims, which they obviously do lol. As I said before, the aggressive offsets of the 9" wide rims
As for determining how the different wheel sizes and offsets will look in comparison to your stock rims, I like to use this site:

Enter the exact tire and rim size you currently have, and the exact tire/rim size you will be going to and it will show the differences.
