Toyo open country AT3 poor wet weather performance

[booch2024]

I swapped out my stock FE wheels and tires after purchase this summer to TRD bbs 18” wheels and at3 275/70/18’s. I’m running them at 35psi and they have been great all summer.
However, once the rains started here in the PNW, they have been crazy slick and unsettling to drive.
The road on my daily commute is steep with many off camber turns and I’ve felt the LC FE slip and slide all over (no leaves on the road either).
For one, I would have thought the full time 4WD would help and 2 the AT3’s updated rubber compound would grip better.
Has anyone else experienced greasy type driving in the LC in the rain around corners?
Think the tires need to acclimate more?
Thanks for any advice or feedback.

Are you sure it's not that the first rains have brought the oil up/off the roadway? I haven't had mine in any significant rain yet, but the Falken AT3Ws I briefly had on my 4Runner were excellent in regard to hydroplaning, and I was hoping these Toyos would be similar.

My thought as well.

It’s been raining here for about 3 weeks solid but maybe.
