The 265/75/16 is a nice size for the Tundra. I had 285's, 2" lift and didn't handle as well on the road. Off road was a different story. If I did it again, I would skip the aftermarket UCA's, install the IVD coilovers again and keep it a bit lower. There seem to be a lot of 275/70/16 LC take offs around for sale. That might be a good size Michelin AT tire without lift.
