35-11.50-r17 Tires and 4.10 Gears

[Az_Ed]

I have a 2020 JT Mojave. I just replaced the original Falken 285-70R17 with Falken Wildpeak R/T 35-11.5R17/LT. My first 2000 mile road trip averaged 15.1 MPG in very windy conditions not driving faster than 75. Most freeway cruising is in 7th with downshifts to 6th on uphills. The transmission only shifts from 7th to 8th during a long downhill. I estimate mileage has decreased by 2 mpg. The new Falken tires ride much better and are quieter. It would be nice to retrieve 8th gear to lower freeway cruising RPM but I'm not going to worry about it.

Azmojave: I recalibrated my speedometer to correct for the larger tire. My speedo is within about 0.5 MPH of accurate. Is there yet another calibration to program?

I have 35x11.50X 17 Nitto Trail Grapplers on my 2022 Gladiator Rubicon with stock Rubicon wheels and it drives great. I use the Tazer mini for re calibrating the speedometer and TPMS (Nitto says to run those tires at 32 psi vs the stock Falken widlpeaks which were 37 psi). I did notice a drop in mpg to around 15 mpg on average. That wheel/tire combo may look a bit skinny to some. I like the Rubicon 7.5 wide wheels which is within spec for the 11.50 wide tire. I may eventually get a wider wheel to accommodate 35x12.50 tires.

Save the re gear for when you go to 37s. You will.

I put 37's on mine 3 days after I took delivery. Started with 35's and when I got home and my wife saw them she said "they look small, go bigger" (no jokes here, please - I have a fragile ego ?).

I have been running 37's with 4.10 for 2 years and I finally had enough of my 4-speed MT. I just went 5.13 over the holidays and I WISH I HAD DONE IT SOONER.

Everyone told me I would...

I told myself (and my wife) I would not...

I did...

You will, too...

Ridge Grapplers are good but I just got Falken Wildpeak R/T and love them. C rated.

I have probably had about six sets of ridge grapplers over the years on various vehicles so obviously I am a big fan and Had planned on going with them again with the gladiator. I am set on 35x11.5x17 for the size and it seems the choices are pretty limited especially in C rating. Unfortunately the ridge grapplers only come in E rating and I have been down that bumpy road before. They are in my opinion too much tire for these light trucks. So what are your thoughts on the Falken RT? Could you elaborate a little about why you like them over the ridge grapplers? I think these are what I will be going with Primarily because of lack of options But would like a little pep talk to reassure myself of my decision ?

One thing to consider I haven't seen mentioned yet is consideration for where you live, and how much weight you have in your truck. It seems so far everyone who has posted are what I would call 'flatlanders'. Not to sound derogatory... I dont know most of the states of members but in the Rockies, you have hills, frequent hills, large hills. Meaning, frequent shifting, stock and unloaded, or heavy and loaded - it doesn't matter. So for this reason, and for weight, I myself plan on waiting to upgrade to 35's until I can afford rehearing to 4.88.

SO just also consider your weight, and where you live as a factor. Tire size isn't the only thing to consider here.

Tons of mountains in AZ. Loaded down for a week and pulling my teardrop is no issue. Gas mileage sucks but that’s to be expected.

How heavy are you loaded down?

Here, with stock tires, I often times downshift to 5th just to maintain speed. Only time I see 8th is going downhill. Hills here are pretty significant. Although I have never been to Arizona so have no experience to base off of. I did spend time in Georgia and North Carolina however.

Decidedly not flat lander here. Regularly make the climb from 5280ft to 11,000ft. Not sure what would be considered "frequent" shifting. All I know is that the ECU does a great job holding the motor up in the rpm band when necessary, yet allows upshifting all the way to 8th for the flat spots. I do not find that the transmission hunts around. It selects gears like I'd select them in a MT.
