What's the window tint percentage on the windows of a Chevy Silverado?

I live in the State of Texas and I want to tint my windows so no one can look in and also still legal. How dark can I make it?

Well in TN I think 35% side and the back glass can be as dark as you want it, but I don't know if all states are the same or not, Sorry!
