Any of this true?
Will the truck look better with 16" wheels?

Rosie, there's a bit of a trade-off here......


The whole reason why Rover went from 16" down to 15" wheels was to help acceleration... the taller wheel took longer to get up-to-speed than the shorter one. However, for each revolution, more distance is covered with the taller tire.

Wider tires are 'more stable' and provide more traction, but skinny ones are easier to turn w/o power steering.

Thing is, a 33x9.5/R15 will be a little taller than a 7.5R16. You can, with either 15" or 16", have different widths or heights, all through tire selection.

Personally, I like the 16" wheel better, but wouldn't necessarily avoid the 15"....
