The wheel shown there with the lock ring and the safety is commonely known as a 3 piece wheel, the other type of wheel with just one lock ring on it is a 2 piece wheel, and then the dreded widow maker,which I don't believe came on pickups but on ton and a half and up were the type that came apart in the center of the wheel,one half locked over the other half,these are the ones that tire shops won't work on,some shops will still work on the 2 and 3 piece wheels.
