3.55 vs. 4.10, which is better on the highway

The truck is all stock, stock tire size, etc. Which will give me better gas mileage on the highway, that is without pulling anything? What should I expect, its a 1997 2WD crew cab?

So you think 18 would be reasonable on the highway, if I wasn't pulling anything?

You could go to 255/85/16 tires next time, gets you partway back to 3.55 without being very much wider than stock.

So it would be ok if I ran 265/75R16's with 3.55 gears? I'm not looking to pull much, and when I do it will be little. I'll be doing about 90% highway driving.

Also, with 265/75's, wouldy you mount them on an 8" or 8.5" wheel? I don't like it when the wheel is as wide as the tire, I think that looks bad. I'm leaning toward an 8" wheel.
