Hey Joey, don't get too wrapped up on what they say about the chains up there. It's amazing how many rental cars from the bay area are cruising around with no chains. Most of the signs state “chains or snow tires required”. Where you get nailed is when the weather takes a change and for some weird reason and it snows heavy in late June. Sequoia and Kings Canyon are not Tioga Pass. But I've seen times where, unless you were chained up, you're stopped along with several others but it’s rare. Even in Yosemite the rangers generally just hold you over for a limited amount of time or turn you around. Now the disclaimer...you're on your own
I’ve never been asked to show my chains, but I’m always in a 4x4.
