Has anybody else experienced this?
Are the sidewalls on the RE-11's a lot less stiff than the OEM's?
With 35psi pressure am I inflating to the correct pressure for this oversized tire?
Appreciate any help.

other people will have other opinions because most people on this forum subscribe to the sizes you mentioned, but if you look at what's happening you reduced your front tire size by 5% and your rear by 1%. You also have significantly less sidewall than previously. The reason you feel a reduction in steering feel is because you increased the difference in size between the rear width and front width (bad for keeping neutral and understeers a lot more) and you're putting more weight on the front tires because you slightly shifted your center of balance (by about 2 degrees raked, so around an extra 33 pounds on top of each wheel). You also changed the stock aerodynamic properties of the vehicle with it being raked forward slightly and if you live anywhere with a lot of crosswind you'll notice it more.
Point is, the sidewall isn't softer than oem, but the compound is and now you're slightly raked, so what you're feeling is a small difference in balance.
99.9% of people would never notice this, so good on you for knowing your car well enough
