Curious what the vehicle was? My own experience is almost the entire opposite, on my Explorer, this is almost the best all purpose street tire ever. Very good wet traction, dry traction, tracking (doesn't follow the road), and as good as any non snowflake rated tire on light snow. For mild off...

Some good points made. I'll add some and say that the Expedition's R&D is fully recouped by now. The current gen came out in 06 as an 07 model, which means R&D occurred in the early 2000's when the SUV boom was still hot. It's now very long in the tooth and the much needed 2015 refresh helped...

The day when emergency response and military combat vehicles adopt the diesel emissions tech, is the day when I know it's reliable enough to trust on an extended remote expedition. For instance, I'd say we're definitely there (and even past) for gasoline emissions technology. No one, including...

Great minds think alike! :cool:

All very good points Frenchie. People are often surprised at how stable OEM trucks and SUVs are, just about all of them can reach the 45 degree tilt point. Like wise, on flat ground with sticky tires, just about all OEM vehicles can hit 1.0g of cornering (steady state) without rolling. And...

We can all argue till we're blue, but we should realized due to the vastness of North America, every region presents a different situation. Animal populations differ, human activities differ, and animal responses differ. Here in BC, the bear danger is very real, much higher than say...

I go a step further an always use a face shield when grinding, even with a dinky 4.5" Hitachi... Years ago when working in a mill, a photo was shown in our monthly safety meeting: a millwright was using a big 7" grinder, and the disk disintegrated. Came flying right into his face ..... shield...

When you do get around to testing it, please keep us in the loop on your findings! I'm really curious of the CFM at different pressure ranges, such as 0-50, 50-100, 100 to 150 and 150 to 200. Without compressor maps this is the closest we get to knowing something's efficiency vs pressure ratio...

This is where we have to be careful in the absence of industry standardized testing procedures. As an engineer I can tell you one of the two companies isn't telling the truth, and I lean towards the OB2. The adiabatic compression efficiency of piston compressors are very similar, given a...

Can't speak for other Gens, but a 4th Gen 4runner is built off a modified LC Parado platform, fully boxed with 9 crossmembers. A very good upgrade over the 3rd Gen's modified Tacoma frame. The early Tacomas had a lot of good things going for them, but a strong frame was not one...

Huh? See plenty of people Fording water in California: :D

Is that one of those pure lead AGMs made by Odyssey? If so, you certainly have nothing to worry as they're rated to 80% depth of discharge! With my starting battery, I don't feel good draining them too much, especially if I air up two trucks. However, for longer trips I have my dual Trojans...

The need for RPM highly depend on your alternator(s). If you're driving a modern diesel with dual 220-amp alts, and putting out 300+ amps at idle, I doubt you'll have to touch the throttle... Even on my Hemi 1500 with a single 180a alt, an MV-50 sized compressor doesn't drop the voltage at...

Put mine on the inside all the time. Even with normal "EPA" cans, I rarely get vapours if I screw them tight. For all people who are concerned with safety - fuel is safer if it's secured within the vehicle's frame / chassis. If you have them in the back, and you're severely injured in a rear...

I am trying to think of a single vehicle component that's affected by GVW, but not GAWR, and can't. Suspension, brakes, control arms, tie rods, etc., are all linearly related to axle weight. Therefore, they shouldn't wear excessively if axle weight limits are obeyed. Powertrain systems are...

Stereo, Personally, I like to take the GAWRs approach over a simple "GVW". This is also what DOT does for every commercial vehicle. In fact, in the commercial world, GVW always equal front(s) + rear(s) GAWRs, which is a lot more logical. In the recreational vehicle market, that's not always...

And even if you can, who can perform the required programming in 20 - 30 yrs? If the PCM on my 2014 Ram burns out in 2040, who will have a retro computer with retro OBD ports to attach it to my VIN and all the keyless / remote system? My Detroit Diesel bus has just passed the 1/2 century mark...

A sign of changing times - a first gen Expedition, while no light weight, is light by today's standards for its size. A 5.4 with 4x4 weighed 5500 lbs. LR3/4s, RRS, RR, first gen Cayenne / Touareg, G-wagen, LC100/200, and modern Expedition / Tahoe are all heavier. X5 / ML / Q7 (sports cars of...

Part of the reason is there're are VERY few capable IFS/IRS vehicles, that's built sturdy and performs well off road. The Land Rovers are the only ones I can think of - highly advanced traction control system and simulated articulation. But even then their lower control arms are overburdened by...

Did you re-program your speedo to account for the larger tires? 10 mpg sounds more like a big block Chevy than Ford 5.4...
