Yes good idea to play with the pressures. When I first started running huge rear tires 20+ years ago I noticed that I needed to run similar pressures front and rear rather than the factory bias.

The tire diameter front/rear bias is the same now as it was when I ran the 15" wheels, I don't think that is the problem. I ran a 1" bias on the Red Rocket as well.

I went out this afternoon (70°F) and hit the mountains hard to really try to better feel what is going on. What I am seeing/feeling is the tires stick - they do not slide like the 345's did, and they just don't feel the same. After rounding a few of my favorite corners I started cranking up the throttle and the tires simply do not slip. I think this may be it, by not slipping and giving me that feedback they are working the suspension harder and I'm not used to that. The unsettled feeling I get could be because I don't know what is going to happen when it does slip. Also tires are brand new which may be at least part of the problem. I'll wait a bit and see if they get better. Got to say I don't like it that these tires don't slip, and I don't know what it would take to get them to do so. There is an abandoned air strip close by where we used to do auto-x, I think that is where I need to go next.
