New rear Tyre for the Zr

Need to replace one of the rears on the ZR, sadly the previous owner had apparently been driving it around (almost) flat and despite being less than 6 months old it's knackered, which is a bugger.

The size is 205/55 R17, anyone know of the best / cheapest place to replace it?
