Let me restate the question to see if this works for you:

Design an IP address schem that will have 120 sites that are each connected to each of 8 rings???  

That's a lot of connections so maybe this isn't the right interpretation?

So, maybe it's:
Design an IP address schem that will have 120 sites that are each connected to at least ONE of 8 rings???  

You haven't said anything about the mode of interconnection between sites so it could be VPN, dedicated lines, MPLS, etc. etc.  What is it?  This affects the IP addressing possibilities.

Also, there are implications in addressing methods that have to do with both the mode of interconnection and your objectives.  What are those objectives?  
e.g.
- Everything on a single subnet?
- Each site on a different subnet?
etc.

Sorry for the confusion. Yes you are correct that each of the sites will connect to at least one ring and have the ability to go around in another direction if one site goes down and breaks the ring.  We will be using someting similar to MPLS across the entire 8 rings.  My thinking is to have each site on a seperate subnet, but the backbone on it's own subnet and mgmt vlan to interconnect the rings for multiple failover possibilities.
