I think desertrat is the cheapest place I've seen them. Might try tirerack and national as well. Just pick up a 4x4 mag and flip through the adds then start calling to get price matching and see what you can come up with.
those will get you started. some places offer free shipping but charge a bit more per tire. some have really cheap prices but GOUGE you on shipping. Call aroud to your local independant tire shops. They will most likely be your best bet for a happy medium.
I ordered a set of wheels from them that took 6 months to get. I got them cheap beacuse the made the mistake of advertising them wrong. Well, I think because I didn't pay full price they screwed with me and didn't give them to me for a long time. I have also tried to buy tires from them before and we got into many arguments about prices for shipping and such because I got free shipping with a promo they offered and then they tried to go back on it saying I had to pay shipping. They are a few long stories that I could really go into an extremely long post about. Do a search on google for 4wheelparts and you will find a TON of complaints about them all over the web. I'm sure you will find some more complaints on this site as well.
marking 4wheelparts off the list...........thanks for the info!
http://www.ntwonline.com also has ssrs. they are located in Wheeling, WV. thats about a three hour drive for me BUT theres also a Cabelas Superstore near it. I'm gonna give them a shout when i get my funding in order. I heard good things about them.
