Big tires, odometer error, and mpg

Recently a friend emailed this miles-per-gallon question: I’m scratching my head here on fuel and mileage numbers. If I do the math for gallons of fuel consumed (fuel filter life % gauge) and odo I get about 16 mpg. But the Ram’s EVIC dash display says 11 MPG. With 4.30:1 gears and 37-inch tires, I know ALL the numbers are inaccurate. How … Read More

Fuel Economy And Wind

Driving in the wind can be a drag, particularly if you’re driving a high-profile vehicle, hauling a camper, or pulling a trailer. We live in an area that often has wind, and unless it’s coming directly from the rear, wind is an impediment to good fuel economy. A perfect, direct tailwind is like the perfect anything, nice to dream about but … Read More

High Gas Prices and Vehicle Buying Habits

Yesterday I received an email forwarded from an acquaintance regarding an AOL story which references an AutoTrader.com survey. The survey was about at what price per gallon car buyers will significantly consider a vehicle that offers better fuel economy. The AOL headline read “Car Buyers Won’t Change Habits Until Gas Hits $6.51 A Gallon“. After reading the article I immediately went … Read More

MPG, Fuel Economy, Tire Width, and Treads No. 1

Will The Most Efficient Tires Please Drive Forward It’s often stated that narrower, lighter, less aggressive tires are more efficient and will yield better fuel economy, but how much better?

TRD Tundra Wheels a 17 MPG Rock Warrior Solution?

Several weeks ago I posted about purchasing a set of OE 17-inch TRD wheels which included the original BF Goodrich All-Terrain 285/70R17 tires (17″ Tundra Wheels & BFG A/T Tires). However those were not the first, nor the best, set of TRD Rock Warrior wheels I have purchased. The Cooper S/T MAXX trial started last summer and has drug on for … Read More

LT255/85R16 Tire Delivery Part 3

Long before my route was paved there were much hardier travelers who passed this way. I stopped for a brief photo and took a moment to reflect. Lately I’ve been reflecting on how thoroughly spoiled we are with easy, efficient, convenient long distance travel. Several decades ago vehicles were not as low-maintenance and relatively trouble-free as they are now. Before … Read More

Real Road Trip TDI MPG

My recent post about attaining 56 MPG in our little VW TDI was a rare achievement, our normal fuel economy is less, but still quite good. A recent road trip to Oregon is more representative of our typical highway fuel economy. The trip consisted of a couple hundred miles of slower, two-lane highways through the Sierra Nevada and Cascade mountain … Read More
