Central Valley CA. Looking for tire chains for snow driving

Where can I get decent tire chains. I am planning on making a few trips to the snow this year

 

NAPA or Wal-Mart

 

I like the scc chains, my sister got me some last year from 4 wheel parts. They are much more durable than any cables I have used before. Just make sure to try them on before actual snow. I've helped countless people, put chains and cables on in mammoth. Even this last weekend I drunkedly helped someone put chains on their truck up in mammoth (correctly, btw, its not that hard, they are all about the same to put on).

 

Thanks. I will stop by walmart and see if they something for me. I am assuming that I only need the tire size for them
