Have a couple questions about stepping up tire size:

1) Yes, I know I want to reduce weight, but (I'm driving around a lot of weight already) isn't there some advantage to getting the most distance out of a given engine crank? Driving my truck, I have engine to spare and low gearing so getting everything moving isn't going to be a problem.

2) My truck,when loaded, is full by volume not by weight, so I have lots of space in my fenders I don't need for suspension travel I can potentially fill with tire without clearance issues. Would filling more of the wheel arch with tire have any of the benfits of installing skirts?
