Just got a quote to replace my 7.50 x 16 Firestone blackwalls on the rear ... $992 AUD . Yup thats two tyres...and doesn't include fitting 
Try pricing up some, say....205R 16. I think you'll be pleasantly surprised, both with the price, and the ride quality...obviously being radials, you'll want to put them on the front too, but, once you've run radials on your truck, you'll never, ever go back to x plies.You can just run them on the back with your yucky bias ply tires on the front, until you've worn them [the front tires] out.
I run the above 205's on the back of my 35, 175R 75 16 on front. Big and littles.
