Seems there is likely a phone app for this now since I watched the DT employee run his phone across the top of all four tires before putting it in the shop for a rotation. No mention of problems even at my low pressures but this set only has 5k on them. My last set wore very evenly, even given the aggressive nature of the tread.

Not something I keep up on... Just found it interesting the tire store employee utilizing it on my truck. Seemed like the intent was check the flatness of the tread surface and I supposed tread depth across the tires would do that.

I like setting them 50 front, 55 rear but when it gets cold for a few days the air pressure drops and set off the low pressure warning. Then I have to pump them back up to 60 and 65 to get it to go off. PITA!
So I keep them at 53/58, which keeps them above the TPMS trigger pressures.
I wish they would have made the TPMS trigger pressure adjustable on the fly, instead of requiring the use of Forscan.

What's really interesting to me is how many people here with unloaded pickup trucks run more air pressure in the rear than in the front, when the front is significantly heavier than the rear unloaded.
I think it shows you can do just about whatever you want when unloaded as long as your pressures aren't unreasonably low.

Super easy to use ForScan to change the thresholds. For anybody wanting to run different pressures, I do not understand why you would avoid changing the thresholds? I think I set mine at 35 front and 30 rear, plenty of warning if there is a pressure loss.
My truck weighs about 3800 front and 2900 rear so I run less pressure in the rear which is where the ride will be upset the most in an unloaded truck. Leaving rear pressure high seems to miss the point and certainly the effectiveness of lowering pressures.

I bought this Forscan adapter, not sure if it’s capable of changing the settings. Plugged it into the truck and laptop. It all looks foreign to me, didn’t wanna screw things up. No one around here or Billings makes Forscan settings changes.

Based on the conversations, It appears that many continue to run higher pressures in the rear even after dropping below factory specs overall is just to keep the low pressure alarm from going off? At what factory threshold will the rear alarm go off for low pressure? My rear was at 58 yesterday before I pumped them up so I know it’s below that.

PM sent, thank you!
Yeah, running 34.5’s and checked my speedometer using the Waze Ap when I’m indicating 68 mph I’m actually going 70.
