I prefer to think of tires as something where you want the service for them as well.
I buy at discount tire. There are so many outlets around here, I never have to go far for free rotations, free flat repair, or warranty.
People shop on price alone sometimes, and they don't get any service or any warranty.
I would also buy tires from Firestone because there are tons of the stores out here also.
When you look at a tirerack deal, that makes no sense to me. You pay basically the same price as discount tire, and you have nobody to mount it at a reasonable price, and you get no service.
Tirerack only makes sense if you have a sports car or an oddball tire size and can't get what you want locally.
For a camry you have a million choices. I ran three sets of falkens on various cars, and they were fine. They are usually the cheapest tire from discount tire.
