    That's my thoughts as well. I am fine running 65 in front. But my truck rides horrible being empty with 65 psi in rear. Take it down to 50 psi and it rides much better and tire still has no sag as compared to frt. Not to mention it gets better traction VS bumpy/chatter in rear

    It was 5*f this morning when I went out to the Truck. Threw the low air pressure warning because it went below 60 pounds in one rear tire. Had to run it up to 70 psi to clear it. Ill be looking into AlphaOBD to clear this one up. I like to run about 65 in the front and 60 in the rear when empty. Bump the rear to 70 when towing the travel trailer at about 7500 pounds.

    Yeah, this is true on a half ton truck, but when at 80psi my rear tires are missing half of their contact patch I consider that a bigger safety issue.

    After dealership blowing me off saying they cant do anything I called RAM. Talked to a glorified secretary that passes information to engineering etc. she called me back and said they cant do anything either! Very upset that they do this to a 50K truck and I have to either feel every Pennsylvania bump etc. or deal with a warning light and gauge showing low rear tire pressure. The truck is empty going down the road, no reason for 65+psi!! My rear tires are not going to wear wrong because I have 50-55psi in them as well as no weight in bed or towing!

    Guys - read back........it's not FCA's fault - it's the NHTSA mandating this.

    Copy, just frustrated. Just seems ridiculous to make a setting so high, not every 3/4 ton truck drives around loaded. And even with 55-60 psi in rear it can haul axle/weight according to tire manufacture well above empty weight of truck.

    Just spend the $150 bucks and get the AEV Procal Snap and be done with it. 5 minutes and no more TPMS light. I’m running Falken 35’s on my 2020 Power Wagon at 45 PSI front and 40PSI rear.

    Obama Diesel Exhaust Cooker warranty expired 80k. 3rd Cooker by 75K so @78k I deleted.
    Saving fuel & costs 10c mile = $1000/10,000 miles
    Or $10,000/100k miles
    So if I deleted, 300,000 = $30,000 fuel & cost savings 2016to2020
