Looking for 18"and 20" Low Profile Car Tires- free or cheap-read ad

I am looking for a couple used tires for mocking up rims on my car.
I need some Low Profile 18" tires and some Low Profile 20" tires.
I want to get the tires mounted on some rims I have for my Chevelle. I need to find the right sizes for clearance before I order new ones. so I am trying to get different tires to see which ones fit the best.
Truck tires wont work unless they are also low profile car tires.
I only really need one of each size and they do not even need to have much tread on them. I will dispose of them afterwards.
I do not want or need a set of 4 of one size, that really wont help me out.I need 2 18" and 2 20" for my car. As long as they hold air, they will work for my mock up.
please let me know what size you have and i will meet you to pick one up.
thanks
