Has anyone been able to set the TPMS below 80lbs in EVIC 2014 2500

[RikDavis]

I easily get 100K and more from BFG's and Michelin's on my Red 98 4X4. Most say I am bull of Barbara Streisand. I run 72 front and 45 rear. Most under inflate the fronts and have edge wear from turning and most over inflate the rears and have center wear.

Do what you want but that's well over 1,000,000 miles of experience and awesome tire longevity.

I agree. I ran 70 all the way around on my 99 . Each set of michelins still had DOT legal tread depth at 100 K miles

 

[Cummins12V98]

No it's a 2500. The last set was BFG's and I would guess they had 25K or so towing they were at 100K with good tread left.

My present 11 Dually has 25K on Michelin MS2's and they look great compared to the General POS tires that came on it. They were 2/3 worn at 25K. I have no idea what mileage I will get with the Michelin's on the dually. But I do know a friend insists on running his 3rd gen dually fronts 55psi and they are rounded and his rears at 80 and they are worn in the center with 40K the tires are shot. His are Michelins. His TV is dedicated to towing the RV.

Does anyone here know what happens if you completely remove the TPMS sensors, as in running a set of wheels without the sensors installed?

Maybe just the TPMS yellow light would be illuminated, but the psi display screen might not flash numbers because there is no data available?

That depends on what year.They will all have warnings but some will have an actual message that says something to the affect system need service

On a 2014 2500, I may have to try and see what warnings/messages I get.

I'd like to reply to this comment. Cummins12v98 has previously noted on an older thread (don't know if it was this forum) about running his 72/45 combo. I ran 55/45 for a while just to get more comfort since I knew the front axle didn't need that extra capacity, but as he mentioned, I did end up getting some feathering on the outer edges of my tires. Since he mentioned that in a previous thread, I decided to keep tabs on that so I was able to catch the issue early. So now I've bumped back up to OEM 60 psi and I'm going to see if that corrects the feathering/cupping issue I'm seeing on the edge. So at a minimum I would recommend running 60 psi on the front axle even though you don't need the weight capacity.

Also, this is with the OEM Firestone Transforce HT tires.

In addition to tire pressure, the tire, truck, and driver have much to do with the performance and service received. I'm able to achieve excellent results on my 4WDs (that actually get used as such) running adequate psi for the load and conditions, which sometimes is only 20-30 psi off-highway (less for lighter gas trucks).

In recent decades, the vehicle in our fleet that has worn tires most quickly has been my wife's VW TDI. It has lots of torque for a little, light car and we often use it, and the twist is hard on tires.

As posted by another here, to which I agreed- the inflation charts are published for a reason... and Your Milage May Vary

Although I can't find the post now! I would like to think the guy who posted step by step instructions on how to change the tpms thresholds! I took this info to my dealer yesterday and they reset at 40psi front and rear. They said it wouldn't turn off the warning light or the low psi flashing at start up. To their surprise it did! They were so happy they credited me a free oil and fuel filter change! Said they'd tried everything they knew to change thresholds and get the light to stay off with no success!

We got a 2015 gasser 2500 at work, regular cab. I cannot believe how stiff the ride is even after driving it for over 5000 miles now. It came with 80psi on all four corners. I checked the door placard and it says 80 for all. My 06 Mega has a light and heavy option. I set the rears at 50 so I didn't have to go to the dentist. It helped but the ride was still rediculously stiff. I just ignore the light.

I must say I haven't been keeping up with the newer trucks. Are the 3500s set up with the same rear suspension as the 2500s? My 06 is plush compared to the 15. I realize it is heavier with the Mega cab and Cummins but I was really surprised how uncomfortable the ride is in the 15. That, and the gasser mileage is pretty bad with the Hemi.

3500's can have conventional leaf springs, or the optional rear air, which is very different from what the 2500 has for rear air.

The 3500 also do not alarm on air pressure, however they have a screen to display air pressure on the EVIC. SNOKING

I've been running 65 front and 45 back for 18000 miles. No problems and a good ride. Front axle weighs 5,440lbs and rear comes in at 3,000lbs. Daily driver, grocery getter, child retriever.

Indytruckchampion posted this on cumminsforum, it is a working fix.

Here is a summary to print out and take to your dealer

Step 1: Go into the BCM (body control module). Go to "miscellaneous functions". Go to "update pressure thresholds". Set pressure to desired settings. Do not try to do different pressures front and back! Even if you run 10 psi difference front to back you won't get a light. If you plan to run 10 psi difference I suggest your "setting" be in the middle of the high and low just to give you a little cushion.

Step 2: Go into the RFH (radio frequency hub). Go to "miscellaneous functions". Perform "RFH replace" and follow prompts. You will need the PIN number for the truck. That can be obtained through Dealer Connect with the VIN number to the truck. When following the prompts - when asked for desired pressure setting - set new pressure levels. You do not need to replace anything - just perform the function to set new levels. (After going to the RFH hub, this option may not come up. it'll say do a key cycle before starting. Do that - boom. Fixed!)

You have to have the PIN number to the truck and be plugged into Witech. The PIN number is only good for 12 hours then it resets so it's not something you can go get once and keep it around. You change the Evic settings in the BCM then when you do the RFH replace function (that's where the PIN is needed) the BCM tells the RFH what set points to keep.

You do need to have the tires set to the pressures you want. As I said earlier - if you're running different front to back I wouldn't go more than 10 psi and I would put the setting between the two. Set your tire pressures to where you want them before doing the RFH replace.

When following the prompts - when asked for desired pressure setting - set new pressure levels. You do not need to replace anything - just perform the function to set new levels.

You HAVE to get the PIN number to the truck. When you get that you can run the RFH replace function and your light will go out.

The pin number does not reset,there is a legal issue modifying anything that is mandated by law.Some dealers have no problem breaking the law -some do ymmv

I agree with Bob4x4, the only time it resets is 3 attempts locks you out, I've never went to 3 to find out what happens after that, and I hope never have to.

it is recoverable but I guess I should not be more specific since it is a security feature to protect the truck

 

[AlFischer]

Tried that about a year ago. Printed and gave the Service Mgr a copy. When I picked up the truck the TPMS warning was out. The work order said "SET TIRES TO PROPER INFLATION" They were inflated to 85 PSI. GRRRR!

Where is there a dealer that will do this?

Well, I won't be buying another RAM! From the Firestone tables the tires would be fine for a 1 1/2 or 2 on truck. I think that would overload the 2014 2500!

 

[Cummins12V98]

See ya! ^^^^^^^^^

Set the darn tires were you want and place a pc of tape over the warning. Better yet trade for a 3500 with no warning if that is better.

I have been simply ignoring it. However it seems like a good safety feature has been destroyed by Ram and our Nanny. and I don't want a 3500 or I would already have bought it. Wonder how the Nissan is. I can set the TPMS on my 2014 Passat TDI at what I want! INTERESTING!

It's in the same menu where you set the amount of emissions you want it to show during a smog test...
