America's tires is a good place to buy tires, they may match online price.
Good overall tire - good tread life + good and quiet ride + good traction on dry and wet that doesn't cost a bundle is General Altimax RT. You should be able to get four installed for about $300, may be a little less.
Since there are about 6 million Camrys in LA, I'm sure almost every tire joint in town has these in stock at a cheap price. You could take the car almost anywhere and be out the door for around $300.
a little less if you don't mind Primewells or some other Chinese/Taiwanese tire - I know America's/Discount Tire carries Warrior which is made by a Michelin affiliate in China while Firestone stores carry Primewell.
