Background: I've replaced the stock OEM tires on all my trucks with a larger AT/MT type tire (been through a few sets of DuraTracs and one set of BFG KO2s) in the 305-315 size. My tire pressure monitoring systems on my old trucks were always set to the stock PSI recommendation, and after doing the chalk test (chalk on tire on flat pavement to see what PSI the tire wears evenly) on these larger tires I always found them to wear the most even at around 33-35 PSI.
Question: I got a new 2020 Rebel 1500, which came stock with DuraTracs in the 275 size (about a 33" tire, quite a bit larger than the normal stock tires that come on Rams). I haven't done the chalk test yet, but I am shocked that the manufacturer has the tire pressure monitoring system set at 45 PSI for front and 50 for rear. I am very confident if I do the chalk test that it will come out the same or similar to all the other DuraTracs I've owned, even though they were a few sizes larger than these.
It just strikes me as way too much PSI for large AT/MT tires like DuraTracs, and makes me wonder whether the manufacturer overlooked that these kinds of tires wear differently than the normal Good Year SRA or whatever other garbage they usually put on the trucks OEM.
Anybody have any insight here?
