Good point, nemo. Luckily, I think he does enough static driving that the reduced rolling resistance will help tremendously. I have to drive about 80 miles to pick him up tomorrow, so I plan on leaving a surprise on his dashboard.

I think the best he's ever averaged is ~ 32 mpg... so I have a goal. I'm not a fan of his transmission, though.

Never heard of that before. My brake rotors have recently gotten a little gummed up from crud. I guess thats what what happens when you "never brake!"

My wife doesn't know, but she is running around at max sidewall in her truck.

Saturday is air pressure check day around here.

Why would you want to lessen the roll resistance of a pickup truck? Cheaper than a divorce?

If Ladogaboy's friend is not aware of the change and continues to drive using the same spacial references, he will need to brake harder to stop within the same distance with the higher tire pressure. This effect becomes more pronounced the heaver the vehicle, in my experience. Not that the higher tire pressure its self causes the brake wear.

I like nemo's point, because it illustrates just how important proper driving techniques really are. I guess the first adjustment really does need to be the nut behind the wheel.

Well, it wasn't as much of a success as I would have liked. I'm sure most of it had to do with driving conditions. On the same trip last week, it was dry with a slight tailwind = ~ 32 mpg. On my trip down today, it was raining with a headwind = 33.3 mpg.

I can definitely tell the difference in aerodynamics on his car, though. The difference between 55 mph and 65 mph is VERY significant. Greater than 10% according to the instant fuel gauge.
