Ken, great question!
I like to research tires on the Tire Rack website. They do their own testing plus have reviews by actual owners - they’ll show you how many miles owners have logged on them. This gives you a pretty good idea how they perform in all conditions, dry, wet and snow.
Your particular truck had four different tire sizes offered in 2011:
The 285/55’s were not the OEM size for 20” wheels. The factory 20”s are 60’s which would ride better due to the taller sidewall.
The Michelin Defenders are top rated for Highway all-season tires on their site.
I’ve bought six sets of tires over the years from them. Shipping is now free and they’ll deliver to a local installer so you don’t have to shlep them around. *You can find a recommended local installer on their website.
If anything, use Tire Rack for research!
Good luck in your hunt!
PS: I’m disappointed in the factory tires on my 2019 Ram 2500 (Firestones) and will be replacing them as soon as they’re worn out or I lose patience with them. They finished 8th out of 8 on the Tire Rack site. Going with the Grabbers when the time comes.
