I've ridden my 2018 Rover > 4000 miles, about 40% road (paved or gravel) and 60% off road. At first, with just Kenda tires & inner tubes, I rode @ 20 psi, sometimes experimenting down to 17-18 psi. I'm 250 and carry about 10 lbs of gear.....making ideal tire psi range considerably different than for a 150 lb rider. After a rear tire puncture (worst kind!) I inserted Mr Tuffy 3XL liners but after a series of flats (woodland sharp sticks, woody thorns) I opted for Tannus Armour inserts (combined with Mr Tuffy liners...not an easy install) I've had no (knocks on wood) additional flats in 2+ years. They do feel heavier (rotational intertia), but you get accustomed to it as normal.
Tannus Armour advice is all over the map re psi recommendations. Most advice centers on riding ~ 3 psi less than you would otherwise. I now run as low as 14-14.5 psi when off road where speed (and less rolling resistance) is less of a factor and ride comfort and tire grip are more important. Tire performance on paved roads/Rails to Trails is notably different @ 14-17 psi than @ 20-21 psi. Increasingly I'm using higher psi when on hard, smoother surfaces OR when I'm on a long ride that will exhaust me and/or my battery.....and where rolling resistance optimization becomes more of key factor, ie you can go faster, further, with less battery at 20 psi than with 15 psi. Life is full of compromises including that the tire footprint is different, and thus wear pattern is also different, as you change psi. Higher psi usage on hard surfaces tends to really wear downt the knobbies centered on the tires.
