Just my two cents, I would run the largest you can with all 6 being the same, you have a lot more options when it comes to tire rotation and also if a tire is damaged beyond repair you have a spare already on the truck without having to worry about which position you are going to try to match. My experience is from owning three Chevrolet dual wheel pickups over the last 40 years and with my '57 5700.
