Would this be a sign that im actually crushing the sidewalls? Car weighs 2390 soak and wet running them at 7lbs. i only have 30 runs on them so far. No issues with consistency or reaction times but id like to not have to buy a new set in another 20 runs

Depends on how many wrinkles.
Up to 3 or so minor wrinkles, with some good space between them is good.
If you can see where the sidewall wrinkles are rubbing each other, you're way low, or hitting them too hard.
Keep raising pressure 1/4 p.s.i. at a time until it slows / spins, or you lose full footprint.
There's nothing like a shoe polish line around the tread edge, and some video to verify good footprint.

Don't forget to check your gauge every once in a while. My buddy put new tires on, same pressure as the old ones, got 2 good runs, then next time out, the car went to trash, blowing the tires off on the hit, put another pair of new tires on, same deal.
Lowered pressure from 9 to 5 psi, no difference, light bulb went off, I got my gauge, tires were at 18 psi. Lowered them to 8 and all was right with the world again.

its way more than 3. its halfway around the tire

Too much wrinkle; you need more tire pressure, less rpm at the hit or less rebound on the shocks. Pick your choice or a combo of choices. I'm sure I left something out but that should give you a good start.
