If you do not care which brand as long as it last long and cheap, I'd look at craigslist for any like new ones. If you can find someone that is selling because of new rims or upgrading after getting a new car, they'll be the best tire for the money you can get.
Also check out who has rebates on new tires, but I've seen enough junk yard tire that IMO they are not worth the money.
