I believe my tires are Uniroyal 275/65R-16 all season truck tires. Yep, I got rid of the old school bus tires long ago. My wheels are 8 lug year 2000 GMC chrome wheels, and if I can keep stray dogs from peeing on them, they look pretty good.
The ride IS better, but I believe new springs and bushings, as Ron says, will make a difference.
Thanks.
