Even if you find 4 of the same used you will need to make sure that they are worn evenly and measure them IMHO.
Even checking the circumfrence may not be enough. Different brands have different sidewall stiffness so your rolling radius may be different when loaded (weight of vehicle squishing them down). Also may even be different due to dynamics of cornering & such.

BLUF: don't put mismatched tires on any 4X4 especially a VX.
