I recently bought tires from Discount Tire. Free shipping and if you call them they will go lower than the website advertised price by quite a bit. No taxes and free shipping .....on top of the additional discount makes it worthwhile.

Best experience I've had buying tires and I've done business with both tirerack and discount.

 

I was going to go with the mamba m2s with wrangler duratracs 275/65/18s. But actually this morning I found a guy on craigslist selling a set of american racing wheels with 33x12.50x18 toyo open country mud tires with half tread left for $500. Even better I traded him some snow tires I had for my truck before I lifted it (they are really small like 245 or something) and $200 for these. So I really only payed $200 for these so cant beat that. Heres a pic. I'm down with them its my first set of tires/wheels for my f150. I will actually post a pic of my truck tomorrow but its dark right now.
