Check out tirerack.com. You can find some excellent deals there, shipping is minimal and usually no tax! Of course you have to mount/balance in addition.

I am going to be selling my 04 lariat wheels and tires (bfgoodrich) soon on ebay, if anyone is interested make me an offer. It will be about another month or so though.

 

I bought a set of 05 18" Lariat wheels and tires (take offs) for my 04 Lariat from my local dealer. He wanted $500, I offered $400 and he took it. They were BFG longtrail TA's and had 15 miles on them. The only reason I bought them was I like the arizona beige accent on the 05 wheels. Figured I couldn't go wrong for that price. Heck, the tires would cost more than that to replace. Check with you local dealers, maybe they will make you a deal.

 

Take a look at Wheelguyz.com. I bought wheels and tires for my 350z. They came mounted and balanced and they gave me free shipping. No one in town or on Ebay could come close to their prices. For my truck I ended up going with Americas tire only because they were the only one's that had the wheels I wanted. Good luck on finding what you want.
