285 width also is a bit wide/bulgy for the overall look of the truck
The proportion is also a factor to consider. The ratio between width and height on the tire will affect how the vehicle feels at speed especially when cornering but also in its safety during emergency shifts at speed, like collision avoidance.
A more "square" section to the wheel is going to be the most responsive and stable. A wider tread v lower height is going to first look like it's a lot wider than the wheel and then it's going to handle like crap. Examples above are a very square 265/65x18 vs the 285/60x18. Now, it's about the wheel width which is 8" on a factory land rover wheel.
The 285/60 is really a pretty bad match and anyone saying otherwise is basically full of Schitt ! Unless you're driving off road all the time, and basically only off road, that section is going to suck for the way most of us use these vehicles.
The 265/65 practically forms a square section resulting in more stable sidewall as you shift the vehicle weight side to side.
For comparison, and even tighter handling example, on a land rover even, is something like a 275/45-20". That tread is even tucked in a little from the width of the wheel making it even more solid for cornering with the tire not deflecting hardly at all even under massive loads.
The wide 285 bulging out and then pulled back in at the rim is the opposite. A wallowing balloon ride.
