My '24 owners manual says all 3500 series come with a TPIS system.....its a little different as it gives you the pressures for each tire, but I don't believe there is any alarm. Appears to be informational only.maybe a touch off topic. Does anyone know if the 3500 drw's come with Tire pressure monitoring ? specifically the 3500 cab and chassis. I assume they do as i believe they were a standard thing. I know that the 45/5500s dont.
