I just went to a larger tire (275/55/20) and I’m curious if I can run lower tire pressure and if anyone has found the sweet spot?

 

Neat. Yours looks like our eiger gray landmark. We run a 275/55r20 bfg ko2s on our offroad set of wheels that i installed tpms in too... running at 37ish and feels fine. I haven't tried to fine tune it past just setting them there. You need to go in to your menu and set the "tyre" pressure to light load... i think if you go under 41 psi while on regular setting it will give you tpms warnings.

@TexasLandmark Yes, 2020 eiger gray landmark as well. Your truck looks great. Thanks for the input on the tire pressure. I’ll have to play with it a bit. The tire shop set it too the factory settings (47 Front, 51 Rear) and it’s a bit much.

 

Pretty sure that factory setting is for fuel milage and weight ratings while loaded so that they don't have legal issues. Comfort isn't factored in... i would wonder if jlr reps lower the pressures before handing over press fleet vehicles lol, it'd be smart.
I have no idea what pressures are best for tire wear.
