On taller wider tire:
Back in 2007 I'd had the truck for about a year so I was well aware of its MPGs and had been tracking them for a while. When I went from 235/75R15 tires to 13x10.5R15 tires I lost no fuel economy as far as I could tell.
I was not expecting that result. I was expecting to lose at least 2mpg since 2007 seemed to be the hight of the smaller thinner tire fad.

The best part is that it is just so simple that pretty much anyone who is mechanically inclined can do it.

I will add that part about having $60 tied up in doing the mod also.
To add to that I noticed that my diesel cranked over faster with out the fan on there. I did the mod back in 2006, with a burned up and under sized power cable going to the starter.
