The DC tires are around $150/ea. new, And they don't make that style of moto-metal wheel anymore, but the one that they do are around $175/ea. So that would be $325ea. X 4 equals $1300, and minus the used part which is usually half the value. so you should be able to get $650 for the set of 4 tires. The spare isn't in the speculation because its not the same as the set.
But they are only worth as much as someone is willing to pay for them.
