This is IMHO a very bad idea. /var shouldn't be on a tmpfs as it is
the storage place for a number of very important things[0]. tmpfs is
specifically designed to be a very fast filesystem for things that need
to be read and written quite a lot, but can be disposed of at a whim
without hurting anything.

If your system needs to read and write to /var enough that you would
see a benefit in using tmpfs, then your system probably *needs* to keep
those things after a reboot and tmpfs just wouldn't be for you.

[0] By default, /var is where any webpages, any e-mail, and all your
logs are stored. For a desktop system, it may be sufficient to put
/var on a tmpfs, but you won't be able to trace back any logs after a
reboot.
