Certainly. I can say that when I have had under inflated tires, I have seen a measurable difference in fuel economy.

It does indeed help with fuel economy, how much I don't really know.

O Archer I can agree on the 4:11 cog,50 mph. on the highway was my pace in a pick-up untill I went to 12.50x 15 tires,gas then was $.60 a gal, I still run that size on a 4X4 vehicle,I keep a large utility sponge fasten under my go-pedel to save fuel,the extra stiffness when heavy on the pedel helps to stay at1/3 throttle or less,but still be able to tromp it if necessary.
The sponge acts somewhat as a foot rest for most normal start-offs,it works as a reminder for fuel savings,W F Me anyway.

Those 4.11 gears will get him started at the traffic lights, but are hell on economy

Weight is another factor the greatly impacts mileage. Don't carry around extra stuff that you don't need to. My dad used to carry around everything plus the kitchen sink in his '74 Dodge maxivan and would get 12 mpg, but it had a big 360 ci V8 engine with a 4:11 truck rearend.

Properly inflated tires is one of many ways to boost fuel efficiency.

The more air in your tires, the less resistance and better fuel economy. I have noticed a difference from underinflated tires to properly inflated, a mile or two per gallon.

"Does having your tires properly inflated really help with fuel efficiency?"
A below recommended tire pressure increases rolling resistance which translates into lower fuel economy. However the bigger problem is your tires will wear out faster and you car will handle more poorly.

I believe my tires are supposed to be inflated at 32 psi. When I went from 30psi to 35psi I saw almost a 10% increase in mpg, maybe from 27mpg to 29mpg.

Tires that are under inflated have a greater resistance than properly inflated tires. Over inflated tires roll easier, but your tires wear wrong. Any time a tire is not inflated properly, it will affect the handling of your vehicle.

Yes. A tire that is 20 percent under-inflated can increase a vehicle’s fuel consumption by 10 percent. Under inflation also increases the rate of wear on the tire, which also decreases fuel efficiency and can cost you money on new tires. It's a no-brainer.
