Maxxis Minion DHR2 EXO.
DC (dual compound) is longer lasting and cheaper, but 3C is grippier, esp in the wet.
2.3 is the min width I'd recommend. 2.4 WT is recommended if you have a wide rim, over 29 ID or 35 OD.
Can opt for DHF up front if you tend to lay off the front brake and like to carve/lean, but DHR2 is a good all-rounder for both front and rear. Aggressor is a worthy alternative for the rear, but I find that the DHR2 isn't any worse at the job. Just listing it, in case it's on sale.
Just don't go cheap with tires. 26" wheeled bikes especially need high quality tires (and suspension).
Alternatives:
Schwalbe Snakeskin casing too thin for hard rocky terrain, perhaps fine depending on the tire model (thick blocks in the pinch flat prone area may be fine, yes tubeless tires pinch). Apex and DD are recommended. SG probably overkill unless you go full Enduro, or ok for rear if you have super short chainstays. Don't bother with the older TrailStar versions--Addix EVO (Soft/Orange front, Speedgrip/Blue or Soft rear, *not* Performance) is the way to go. Magic Mary front, perhaps the new Hans Dampf for the rear.
Continental performs fine, but I honestly never wore one out due to various problems like casing tears, sealant weeping, just not holding air. I liked the Trail King 2.4 ProTection for the brief time I ran it (torn casing).
Dunno who else makes worthy 26 tires, but if you go 27.5 front (mixed wheel size is gaining popularity, and lots of nice 27.5 forks like the new Lyrik):
Specialized Eliminator GRID (2bliss Gripton) is a tire I've been wanting to try. Butcher is a fine choice, but seems to work better in moister conditions.
WTB has some good options like the Vigilante. Lots of options to choose from based on your style.
Kenda Hellcat has seriously impressed me, but you gotta be fit to run it, due to high rolling resistance.
Bontrager decent options options from the Team Issue line. Didn't really like the lower end line tires.
Vittoria decent options... nothing that stands out.
Eh, just go Minion. Really, should be that simple. They are the kings in SoCal. Should only be a choice between DHF or DHR2, width, and compound, according to your style.
P.S. weight weenism is going out of style.
