Do you guys running 18's find that 265/35R18 gets squirrelly sometimes?

Ok guys, I think I solved this. I decided to check my tires pressures and found that a couple of them had lost a psi or two (passenger front and driver rear) relative to what they should've been. I went ahead and adjusted the pressures down equally in the front from 36ish to 30ish and the rear from 34ish to 28ish.

Now the car tracks straight as an arrow on the highway and cornering grip seems to be up, but on the flip side, my steering/turn in feel in +R has gone from stiff and heavy to light but direct. Is this a common occurrence when running lower psi on 18's for better grip? What sweet spot do you guys use?

tire pressures should be 35F and 33R

Interesting. Even though with a stiffer tire (with a high load index) like the Cup 2's, the load capacity at that pressure would be significantly greater than the stock setup?
