The 285/75R16s look good, but there is a MPG and acceleration penalty due to the size and weight of this tire (all else equal) compared with 245/75R16, 265/75R16, or 235/85R16. And yes I have personally used all those sizes and experienced the MPG/acceleration loss. And yes I have bought them again anyway, but not on a daily driver.

I posted a detailed review of different truck tires that I have had personal experiences with in another thread last week; I won’t repeat it all here. If I was going to go out and buy tires for my 1991 K2500LD (the 6 lug ¾ ton referenced in this thread) which is basically the same truck as you have I would go and get Michelin LTX M/S2 for their superior on road handling. I hate running mud terrains or aggressive all terrains on pavement. And I have offroaded the M/S2s, they do ok unless you plan to load them up with mud or really soft soil. Typical dirt road/rocks/fields/etcetera they do fine. On road they do excellent.

If you want more aggressive looks, I would try to stick to a true all terrain, not a mud terrain in all terrain wrapping, unless your truck is a trail rig, which I don’t think it is. At least around here trail rigs aren’t measured in MPG, they are in YPG. (Yee-haws per gallon….)

For good looks/ok performance, which based on your thread is what I think you are after, I would get 265/75R16’s. If you weren’t posting this question on a fuel economy forum, I would suggest the 285/75R16s. If you weren’t after looks I would suggest the 235/85R16. If you didn’t want to off-road I would suggest the 245/75R16. Oh, and stock on my 1991 Chevy truck was LT225/75R16, for reference. Check your speedometer with a gps after any tire swap.

If you want to have your cake and eat it too, get two sets of wheels, one onroad and one offroad. However, the downside is that you don’t look nearly as cool parked outside of the mall. Personally I can live with that.
