In this case you can use Dynamic tunnel but make sure the other end is getting the ip address from DHCP.

Don't know if it can be used with a single site-to-site VPN, but DMVPN can use NHRP to support non-hub with dynamic tunnel IPs.  The client is configured with a hub's IP, and it uses NHRP to register its public IP with the hub.  The hub then "knows" the remote IP.  (NB: it also supports the remote IP being changed.)
