28 psi in both; 27.5" Minion DHF up front and a DHR in the rear. No inserts, tubeless. Commencal Meta AM 4.2.
28 gives me a good combination of grip, support, and roll.

And came up with: 24F / 27R psi.

155lbs intermediate
Maxxis Minion DHF tire - 2.75x2.50"
Maxxis Dissector rear tire - 27.5x2.40"
Stans Flow MK3 Wheels 29mm width

Not entirely related but am new to tubeless and losing a few psi per week, need to figure out if that's normal or not...

You will lose a bit of air. Nothing to worry about.

Could be running low on sealant maybe add a little more? Couldn't hurt.

200 lbs with my gear on. 2.4 Continental Der Baron 40 psi front and rear. No inserts. I never flat until I wear too much rubber off the tire carcass, then only from goat heads or cactus. Sharp rocks everywhere here in the Rockies.
All is klar herr kommisar!

Around 105kg (230lb), be a bit more with gear.

Tubeless on 30mm ID rims, no inserts.

Bontrager SE5 29x2.6 front - 21-22psi
Bontrager SE4 29x2.4 rear - 25-26psi

Seems to work for me.

70 kg / 155 lbs.

Assegai EXO+ front : 1.2 bar / 17 psi.

Dissector EXO+ with Tannus insert rear : 1.5 bar / 22 psi.

That being said, I know that's the pressure I like with my pump, but it's probably off by quite a margin. All I know is my tires are quite at a low pressure.

New to tubeless too, mine lose air between rides, just check pressures before every ride.

99kg /220lbs

29x2.4 Magic Mary Super Trail on the front, 23PSI
29x2.35 Hans Dampf Super Gravity on the back, 26PSI

Enduro riding, still trying to find the right pressures on a new bike but seems to be in the right ballpark, could probably be 1PSI lower front and rear but don't like tyres too soft

Don't know how you +200 lb riders are riding less than 25 psi in the rear. I tried it for a time last year (w/o rim protection) and I was getting a flat every 3 or 4 rides. Tried it again this year once I got cushcore and my tires were burping like crazy. Not too mention I was getting the occasional rim impact (over the cushcore). Maybe I just have poor line choice

what tires are you running? Are they Dh casing? How wide are your rims? These could all contribute to why your getting flats.

Tires were WTB Judge 2.4 w/ tough/high drip casing mounted on We Are One Union rims (30 mm). Tires were tough as hell but I was still getting flats running 25 psi; over 28 psi and I was ok. I've since added cushcore and haven't had a flat yet, but I'm still running 28 psi. Experimented with lower psi but it was burping lots (lots of sealant juice on the rim after every ride).

Don't know. Never had an issue with a flat since tubeless. 800g is about my limit on tite weight, I don't do big jumps, but I will hit rocks and such at speed. Idk that I have ever really hit the rim. I do try to pick decent lines, unless I just want to let the bike eat.

Yes, that could be. I haven't touched it yet to risk some maintenance induced failure during peak riding season... ha ha. I have a feeling you are right though and I need to add some more and see if it's better.

I’m 190 with gear running 27psi in the front and 29psi in the rear with dh tires and cushcore and I still smash wheels on a 2018 transition sentinel.
