I just got my new tires!
They are Hankook Dynapro, 265/75-R16 ATM. I have these on 2010 stock 16" wheels. 31.7 inches in diameter, width is 10.43 inches.
TC at Discount Tires Direct helped me out. He was even nice enough to not poke fun when I had to call back and modify the order because I read the numbers incorrectly. I ordered the tires Friday morning, and they were here by Wednesday afternoon.
