Availability kind of depends on the size. For the 17s I’d look into Michelin Defenders, Continental Terrain Contact AT or HT.
For the 16s I’d look at the General HTS60 or Michelin Defenders.
These are all tires I see hold up well full size trucks. They should do very well on gravel and decent for light off road. The General/Conti offerings show 12/32 of tread when new in the sizes you listed.
