The last tires that I bought I found on Craigslist. I didn't need them at the time but were such deal I couldn't pass it up.
The guy bought a new truck, drove it across the street and had new tires and wheels put on and sold the take-offs on Craigslist. They were the exact same tires and wheels I had on my truck.
I paid $425.00 for 4 mounted P265/70R17 on factory chrome rims and he even gave me the chrome lug nuts that matched the rims.
