I've always ordered through Walmart but was looking for a better deal online. Having never dealt with any of these other tire sites such TireRack, etc. I was looking for some advice. Have any of you ever bought from any of these places. Don't want to order 4 only to find out they were 2nds or company rejects. Looking to buy Michelin, Bridgestone, or Goodyear with at least a 60,000 mile warranty. Thanks for any help you can give me. Bob
