Best bet is to ask the tire dept Larry.
I would call and ask. You might want to stop & get them closer to big bear or elsewhere along the way on your trip (theres never any need for em in hb, so I doubt the local walmart would carry them)...Or try sports chalet, rei, etc. Will be more likely to have them.
You might call them and ask. Alternatively, you might order online.
Most Wal-Mart's do carry them in stock during season
I didn't think our Walmarts out here would carry chains. I have never thought to ask, Sorry!
