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 the transcontinental railroad, traveling across The States was a serious, life-threatening endeavor. As modern motorized backcountry travelers there is always the possibility that our machines and computers will fail and we will be reunited with primal overland travel; walking.

Below is a poor grab shot through windshield glare and at a substantial distance as I drove through the small town of Quincy, California. It’s not everyday that one sees an nicely restored original Bronco with uncut rear fenders, and nice, narrow original size tires.

Onward further into the country where I met Brian and his family—very kind people. Brian and I visited for over an hour, talking mostly about trucks and tires, before I started reversing my path.

After several miles I drove down a dirt road where I enjoyed lunch. I really like having a tailgate for picnics, one of the advantages of a pickup over most utility vehicles.

Excellent Highway Fuel Economy

After lunch and enjoying the sights and smells of the forest, my fuel economy mission resumed. Theoretically, there are many ways in which to improve fuel economy. Though if your vehicle is outfitted the way you like it and your maintenance is up-to-date, the best way to increase fuel economy is to drive slower and pay attention to your driving technique—there is more to it than simply lowering your top speed.

My not-so-speedy-delivery was a 183.7-mile all highway roundtrip, on which the 3UR-FE 5.7L aluminum Toyota V8 consumed 9.761 gallons of gasoline. The math says that’s 18.81 miles-per-gallon. Excellent.

I’d love to attain this type of economy all the time, but mixed driving, living at altitude, and driving up and down mountains makes it nearly impossible. Though for a lifted truck with a big gasoline-powered V8 engine, and reasonably large & wide 33-inch LT285/70R17D tires (Dick Cepek F-C II), being able to top 18 miles-per-gallon is an accomplishment. Some of the credit has to go to the very tall sixth gear overdrive, which lets the engine lope at very low revolutions-per-minute when lightly loaded, and use little fuel.

LT255/85R16 Tire Delivery Part 2

With a bed and trailer full of tires & wheels I was off to see my tire guys for dismounting, mounting, and balancing so I could get my 4WDs off jack stands and rolling again. A few days later I loaded the bed of the Tundra with the Bighorns and Cooper S/T treads, as well as one old Multi-Mile Wild Country TXR so Brian would have a proper 255/85 spare.

Years ago the TXR was a big seller for the western tire chain Les Schwab. I really liked the void ratio of the TXR—not an A/T nor an M/T—and I purchased a few sets over several years. However, they were not the most rugged tire and tended to cause a steering wheel wobble. The last rig I ran the TXR on was my 2005 Wrangler, which was not as tolerant of their idiosyncrasies, so I moved on to better tires…and have yet to stop.

I had a few goals for this little trip; deliver the tires, meet my new friend Brian, enjoy a country drive, and conduct a mileage test. After fueling at my local filling station and resetting the trip meter, it was time to roll with a goal of keeping my speed at 65 mph or less.

Through the cities and into the fertile Sierra Valley I drove. It cost, but one of the features I enjoy on the new Tundra is the satellite radio. There are a few stations I like, but I seem to listen to Outlaw Country often, Steve Earle came on singin’ Hillbilly Highway.

A New Tire or Two

Old TXR 255/85R16D spare and a Not so old Dick Cepek F-C II 285/75R16D

Several weeks ago I cut a sidewall on one of my LT285/75R16 Dick Cepek Fun Country II (FC II) tires. The story about the sidewall cut and trail will be told later, but with only three FC II treads on the 4Runner I was in need of at least one new tire. Since I had been running a close enough 255/85R16 spare, I decided to buy two FC II to insure I had the exact tire in the unlikely event I ruined another casing in the near future. My calculations indicated that if I rotated the older three tires on one side of the car, all with 3/32″ of wear, and the two new ones on the other side, the wear would even out over the next 30,000-miles.

Most tire warranties don’t cover off-road use. This is term is open to interpretation, as many state and county roads in the rural west are not paved but are still very clearly roads. Regardless, since the three older FC II treads had been purchased mail-order and were not covered under any road hazard warranty, I decided to buy the new tries mail-order as well. One of the local tire shops I do lots of business with would have mounted & balanced the new treads for a reasonable fee, but I decided to play with a little old school technology and balance them myself. It wasn’t easy.
