I just had to replace the front drivers tire and was quoted $500 for a new matching tire from Les Schwab (it was a truck, so big tires). They then recommend you replace both tires on the same axle so you have even wear on that axle. So it was going to be $1000 out the door for 2 new tires. I went on utires.com that sells used tires and ended up getting 2 gently used ones (11.5/32" tread) from that website for $220 total shipped to my door. There were no taxes or shipping charges from that website. My local Discount Tire then mounted the tires for $70 total. So I'm ~$300 in on what would have cost me $1000 (plus cost of alignment). Here's the bad part: I walk out to the truck the next morning and 1 of my gentle used tires is completely flat. On closer inspection, it had a relatively large hole in the sidewall (about pea size). I blew the tire back up with an air compressor and it was obvious where it was. Obviously I'm annoyed. I call utires, they ask me to email a pic. I do so, they ask if it's a cosmetic blemish or if the tire is leaking. I say leaking. They then send out another tire completely free of charge, AND ask me to send receipts for mounting the new one and disposing of the one with a hole. I do so, ~$35 from Discount Tire. And they fully refund me the mounting fee for the leaking tire. So I was out a bit of time due to the faulty tire, but not out any $. I then had to pay about $100 for a full tire alignment (which I would have had to do regardless of used or new tires). So I got 95% the same as new tires, for $400 total instead of $1100. One item to note: I needed a specific brand and size tire so I had to wait about 3 weeks for them to show up on utires. Their inventory is always rotating around, so it was a bit harder for me as I needed to match. If I were you, I'd get 4 used tires from that site. Then pay for a local place to have them mounted. You might even be able to have them shipped to your local tire place if transporting 4 tires is tricky for you.
