345 30 19 Toyo’s etc.
Hey I’ve been using 27 28 (warm) psi for this size, I have a pretty good feeling that is low as hell!!for such big ass tire I’m only @630 whp what are you guys setting yours at with similar hp or higher. And are able to MASH it and still hook VS rolling into it (Fyi the sticker on the door psi rating is for Oem tires)

There is a pressure calculator on tirerack. Put in oem then new and it gives you an adjustment. Maybe start there.
Or here... https://tiresize.com/pressure-calculator/

Okay cool 25 psi with 325s and you hook!! Hence why I think with 345s which is much bigger my pressure is off 27/28 psi. For all driving/roll racing/ drag IT’s people with way more hp than me and hook with the same damn size I have. I’m looking for real world psi like you, not what’s on a plaque.
