now that I have confirmed the 18 inch are not a staggered setup and the 4 tires are all the same size, what tire pressure should we be setting them at? on the door jamb is says 34 front and 42 rear but on the gas flap it says 35 front and 36 rear.

Shouldn't they just have the same tire pressure on all 4 since it's not a staggered setup anymore?

I always go by the gas flap pressures. I am sure either would be fine. Often times the fronts and rears have different pressures even if the tires are the same. The loads on the tires are different. You can always feel free to play around within the acceptable range to find settings that you prefer.

I currently have mine set at 35/38 cold.

Taken from page 376 of 2014 Owner's Manual:

Tire and Loading Information placard:
Recommended tire pressures
The Tire and Loading Information placard is
on the B-pillar on the driver's side
(Y page 383).
The Tire and Loading Information placard
contains the recommended tire pressures for
cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehicle
speed.


Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap.
Example: tire pressure table for all tires permitted
for this vehicle by the factory
The tire pressure table contains the
recommended pressures for cold tires for
various operating conditions, i.e. differing
load and speed conditions.

Read ALL of the section of Operator's Manual on tire pressures. On my 2010, TP's are confusing. In manual, it states higher TP is for driving 100 MPH or more!
I use the "normal", lower pressure on filler flap and then add two lbs. for cold pressure.
