My truck (03 3500 Silverado) has Hankook tires, came from a fellow racer, Ronnie Maggart. I swapped to 19.5" wheels (Vision), and I'll never go back.
I actually ended up with a pair of outer rear wheels that have rivets like Centerline wheels that I need to sell.
If you want to do what I did on a budget, you can find the GM 19.5" steel wheels on vendor trucks (bread companies, snack companies, tool trucks, etc).
