1st off , thanks for the quick and in depth reply.

I went straight to 35x12.5x17 nitto trail Grappler M/T since that's the biggest I could go without a lift and gears.

Just now getting to 1k miles and really checked rpm and shift with the Falken 33s and after the switch.

I used jscan to reset speedo for tire change

Lost 2 to 3 mpgs and don't hold 8th as earlier with the 35s

This calculator says I now have an effective GR of 3.55 and need a 3.99GR to get back to the stock torque curve. A 4.10 now would be perfect with a little more holeshot and be just shy of the 4.22 I would need with 37s.

https://tiresize.com/gear-ratio-calculator/

I had to go from the oem 4.10 to 5.29 when I went to true 36 tsl swampers on my 85 4runner.

We have the same trucks, do you have a build thread with pics, be nice to see what mine might look like with youruprising?

I personally didn't like the OE gearing and I hated a short time I drove with 4.10's/worn 37's, so I can't imagine wanting to re-gear with only 35's. I only drove 20ish miles on the 33's before swapping a little spacer lift and 37's to head for Death Valley the next day...... My thought in this was the Ram geared for fuel economy came with 3.21's and that's kind of where 3.73's and 37's fall. We have a super deep 1st gear and if you have a Rubi, there's even more gear multiplication.

Gearing numbers cannot be compared with any other old skool powertrain especially anything gas. The 5/6/8/10 speed autos have been a game changer and are a lot more tolerant of tire/gearing mismatches. I personally don't care to tow or climb hills in 7th or 8th. I prefer the use those gears for flat land unloaded fuel economy. IDK what my truck would have gotten stock, but I regularly see 23-24 mpg on the road even in the mountains on my 38's so I can't complain one bit.

I do not have a build thread.....too poser for me. I built it as a tool for my wife and I to travel in........Don't care what other people think. ;) See if I can dig up a pic.

At the start of the conflict prices spiked dramatically as a direct result of the market disruption the war caused, coupled by western boycotts of Russian crude. Today there are more factors but the Russian oil boycott still is not helping. My comment was really referring to the difference in price between diesel and gas. At the wars start the delta between diesel and gas jumped from 10-20 cents to $1 or more. The delta cost has never been that large in all the years I have bought diesel. News agencies were reporting that the Russian crude was especially good for diesel and home heating fuel and that was a prime reason for increase in the delta cost. I'm certain there are more factors in fuel and gasoline costs, but that report is what I was going on
While this sounds really good the trajectory of fuel prices was set prior to Ukraine Russia….. sorry.

I think it’s very easy for folks to get so wrapped up in Russia/Ukraine…. I think you should spend more time reading about opec and really how “large” of a player Russia is to American consumerism and our importation of fuel from them…. This debate can literally stem pages and pages of information. And frankly I don’t care enough to feed the beast…. Don’t fall to the media headlines- critically think about what is going on. What is happening in the Middle East and the decisions of opec are where and why we have seen and will continue to see insane prices at the pump.
Another thing to remember is that the media operates in a fashion of smoke and mirrors. It’s easy to draw the eye and point the lame on Russia/Ukraine…. There are so many other things happening, it’s crazy.

if you were to say Russia/Ukraine is why europe is SOL for natural gas you would be correct….

Don't pretend to think you're smarter than everyone and others don't think critically. Of course OPEC plays a role. An example of that was also recently covered in the so called smoke and mirrors media. (By the way, "smoke and mirrors...media" implies that media, a group of hundreds of independent organizations, conspires. This is nonsense and not an example of critical thinking)

OPEC has always had a record of cutting supply to keep prices higher. They are a suppliers cartel and that's what cartels do. The war afforded OPEC more power because western buyers chose to boycott Russian oil giving us less options for supply. Middle East politics plays a role, as does South American politics with Venezuela, as does the Ukraine/Russia war. Lack of Russian oil in the US market is the only example I know of that explains the increase in the delta cost of diesel over gas. Which is what I was referring to originally.

Concur on all but the Russian parts of this…and while avoiding domestic politics so as to not get banned….I would add that scaling back oil operations and infrastructure in the U.S., such as canceling and not renewing oil leases or halting pipeline development, has led to higher gas prices that would have offset market volatility tied to Russian oil. Attributing gas prices to Russia’s war in Ukraine is mostly disinformation and unproductive. Lack of Russian oil in the market is not the only factor for diesel outpacing other blends. API asserts that prior to the Russia-Ukraine war, the “U.S. was not importing any finished gasoline from Russia. In 2021, the U.S. imported 200,000 barrels per day of crude oil and 470,000 barrels per day of petroleum products from Russia, mainly unfinished oils and motor gasoline blending components. The volumes are small in relation to total U.S. refinery production, which processed and consumed nearly 30 times more in 2021, per EIA. Consequently, imposing a ban on Russian energy import could largely be symbolic and not greatly affect prices per se.” A lack of Russian oil is not why our diesel prices are higher than other blends. Lack of U.S. and Canadian oil in the market is a factor. Our biggest problem on oil is domestic production and political division and motivation. That said, diesel pricing is more sensitive to crude price fluctuations than other gas blends. Crude pricing could be lower if the U.S. and even Canadian output was higher…a la Keystone and other pipeline projects.

Interesting articles. Here is one discussing the increase in the difference in price between diesel and gas. The causes cited go beyond Russia, but the war was a factor in the recent steep increases.

https://www.freightwaves.com/news/d...nd-crude-gasoline-and-likely-to-stay-that-way

Bottom line: this analyst sees the price of diesel to continue to increase compared to gasoline, into the foreseeable future. I guess this is one more reason Stelantis is moving away from diesel engines. Diesel emissions are higher, production costs are higher, and now the diesel vs. gas fuel cost increases offset any advantages in MPG. What the thread called? Damn Diesel?

Bottom line is I don’t give a fiddlers fuck If Russia wipes Ukraine off the map not my/our fight, more over no one asked me if I was willing to send billions of dollars to one side or the other. No one asked me if I was willing to pay insane prices at the pump to ban oil imports from Russia. The whole fucking war is pointless. Putin is a bully and Zelenskyy is a begging pauper. Just like every scumbag that collects welfare in the USA. Just keep giving them handouts and they will just keep taking them. And then they will cry when we stop. How about We stop funding foreign governments and try cutting taxes instead??

Oh and yea I loved my diesel! They just need to make it reliable… and fix the towing heat issues… and put a different pump in it..

I am at 15k and its second oil change and i love this jeep. It is clearly restricted by emissions which is terrible.

Took a 140mile round trip yesterday in the JTRD yesterday and nothing happened. No de-rating, no catastrophic oil leaks, no fuel pump implosions. Nothing But tons of torque. For reference, 2021 rubicon on 35s with roughly 18k on the clock.



(sorry, I don’t mean to make light of those that are having issues, but need to speak up for all of us who aren’t.)

I’m very happy for you. I’m looking forward to the same experience hopefully soon. After 3 trips, three times in limp mode, a the successful replacement of the turbocharger after over a month wait, I’m looking forward to getting back on the road. (Waxing my beloved stingray today) I may be doing it solo for a while though. Things only seem to fail deep into the western deserts where cell service is not available. My wife points out that this can be a matter of life and death. She has a point and will be following me in her Rubicon for safety presumably.

Jeep Customer Care was really great. I understand the supply chain issues and I am not blaming anyone.

I’m hoping to have a Conqueror UEV-490 or UEV-14 sometime next year. That’s about as big a trailer as I want to tow. I’m curious how that will go. Haven’t had any issues with the diesel so far beyond occasional belt (?) squealing on start up.

Also, am I correct in reading that some of these derating issues are related to wire harness issues rather than actual engine overheating or is that still just conjecture at this point?

JFC... What a terrible take. The Ukrainians are shedding their own blood on behalf of the entire western world. Dollar for dollar this is by far the best money the US government has ever spent on defense in the past three decades without a single US service member having to take a bullet to boot. Really, if any of us were wringing hands over the cost of fuel than we should have bought a Prius.

The point being that the gladiator is a trade-off between capability and efficiency. There is no free lunch and the capability costs at the pump, pure and simple. Perhaps you've considered that the legacy the jeep brand was built on - the plucky warfighting vehicle that helped defeat the Nazis, is wonderfully similar to the Ukranian David defeating goliath. ?

7717 miles since July purchase. Drove it to the west coast and back, no issues. Just drove it to the east coast and back without issues. Annoyingly, it sometimes hits 32 mpg.

Only the small stuff in life to complain about. I still think the turn signal lever sucks. Cheap and flimsy. The design should be rugged and match the two shifters. The windshield has never met a rock it didn’t want to mate with. The map app keeps insisting that the speed limit is 65 mph just about everywhere. And the damn thing refuses to balance a cup of coffee between the emergency brake and transfer case shifter, speaking from experience as a 4-drink couple.

On another note, had things totally go wrong while feeding a squirrel from the vehicle in a public park. He climbed up on the hood in pursuit of more almonds, but refused to pose for a picture.

So, yeah, nothing but huge problems with this damn diesel thingy so far…

Yes. One case of limp mode was simply a plug coming loose on one of the 35,000 wiring harnesses. I swear there are more wires on this thing than my last three houses combined.

Oh. And I stand with Ukraine. They are being slaughtered by a neighboring madman. I cannot ignore their predicament.
