@gubbinalia - interesting as I don't often see a rider that is my height/ weight. 6'2"/ 190 lbs on an XL bike. I am running 21.5 psi front/ 23 psi rear on my Arrival 130 (140-150 config), which is my current 'short travel' trail bike, with Wolfpack Trail (front)/ Cross (rear) tyre set up. An amazing light tyre by the way. I also run 21.5 psi front/ 23 psi rear on my Arrival 170, which is my 'doing dumb stuff/ burlier trails' bike, with Michelin Wild Enduro  Gum-X FRONT (front) and REAR (rear) tyres. Heavier tyres with stiffer casing including a deliberately stiffer (33 tpi) casing on the rear tyre. Both those bikes run We Are One Convergence Triad 32 spoke wheel sets (30 mm inner). I am one of those OCT types who does use TyreWiz 2.0 (as I am also data logging for components testing for SRAM) so I generally have an excellent idea of my tyre pressures and I also run multiple set up laps for each new bike and any new component to find the ideal set up. I might drop my psi by 1-2 in early spring and late autumn if I am riding wetter trails more slowly however I find I am pretty consistent with a working pressure for my tyres/ weight/ riding speed and skill level. The only bike I run inserts on is my 2022 Sight VLT and mainly due to the additional weight of the bike and the fact it is my only mountain bike that doesn't run carbon rims. I also don't ride it as much as my other bikes so as a result I find that my timing can be a bit off when I ride it meaning that the wheels are more at risk of a negative terrain interaction. It has a DT Hybrid 1700 wheelset and I have Tannus Tubeless liners (what they are now clearing as the Classic), which doesn't really provide full flat tyre support, although I have managed a decent Rupert with 6 psi in the rear tyre when I had a faulty valve day a couple of years ago. Even with the extra weight of the e-bike I am able to run 23 psi front and 25 psi rear with Michelin WILD Enduro FRONT on both wheels (better rear grip and braking on the heavier bike). I think that the liners do some sterling work on keeping the rims true on this bike.
