Looking for help picking tires for my K10

[Richard]

Don't mind a bias ply tire as long as I use it 90% off road. Both of those Interco tires you listed will be lucky to get 20k miles out of them. If you are good with that, great. My tire choices for trucks in the last few buys, including the choice for my new build are Toyo's or Nitto's. Usually 50k+ unless destroyed. A 12.5 wide tire on a 7" wheel while out of most manufactures recommendations should work fine. On one of my trucks I run a 235 Nitto Trail Grappler on an 8" wheel which is out of recommendation and tires are wearing well.
