Generally speaking, you will find lots of high mileage tires with T-ratings, but there are good tires that last a long time with H-ratings.
However, I would pick tires carefully. I've had T-rated and even S-rated tires that seemed to last forever (I even got close to 100K on one set), but rode really stiff and grip was terrible.
These sites have a lot of reviews on tires.

One tire I wouldn't recommend on a Camry are Falken ZE-512s. It's actually a good tire in terms of grip, ride, and quality and even price, but was just too loud.
My dad installed Good Year Regatta IIs on his 96 Camry many years ago. I liked those tires, but can't tell you how the tires were on the long-run because he sold the car not too long after putting on new tires.
