x2 wagner oex, but it isn't that hard to check your brake pads bud, just look at them. Ram oem have always been known for shorter life span then others, if your rims are constantly dusted well that dust is a combo pad material and rotor material. I'm changing mine just because I'm tired of seeing the dust, oex dust much less, pairing that with e coated rotors. I would say it is a good idea to just get new ones at 40-50k miles and get oem junk off. I'm not sure about the Cummins pads, if they use a different brake, I would hope so but who knows. Most brakes will probably last longer, like 70-90k, but I like to change the first ones out, but that's just me.
