Is anyone looking to unload some used tires that fit the bill?

I have a slow leak in one tire, probably drops about 4-6psi a week. Since I don't drive to work and only a few times a week I just plug in my tire inflator, top it up and head out. But it's beginning to get a little annoying. I'll be purchasing new winters before next winter but just looking for a quick fix for the next few months.

I won't really want to put just one on since there'd obviously be uneven tread wear.

I'm in the GTA....willing to arrange $$/pickup.
