Continental HDRs are hard and not real good traction. You could spit under the rear tires and need to go 4wd to move. They have good tread depth and seem to last a long time. I had 70,000 miles on a set and still had 1/2 the tread depth remaining.
I previously had a set of Michelin XDS and did not like the noise. Sold them and installed a set of Michelin XRV tires. I still have them. Sold the Continental HDRs with the truck.
