Bought truck (2020 2500 Tradesman 6.4) 3 months ago. Left dealership and truck was horrible driving, felt every bump through out! I drive 12000 mi a year, less than 1000 is hauling camper 3 times a year. I air up accordingly then. I lowered it to 65 Frt and 50 Rr and it rides 10 times better. Of course the tire low light and message/picture popped up right away. I took it into dealership at 3000mi for 1st oil change and requested the technician to fix/adjust my parameters. Service righter tells me after service is done that the cannot adjust TPMS because its programmed like that! Ridiculous!!! So I have to drive around with these lights/symbols on my new truck. I called RAM and put a claim in on issue, awaiting there response. There is no reason for an empty truck to drive around at (there minimum 65 PSI).
