5 psi oil pressure drop?

Also might want to check your oil temperature. I used the trans sensor of the Quadzilla in the oil plug on top of the oil filter housing. Hotter the oil thinner it gets. I typically see 168°F to 175°F in engine oil temp. Being your running larger tires and lower gear ratio could add more heat to the oil causing a drop in pressure too. As seen below 105°F daytime temperature.

 

 

245/75 R16 tires making final ratio to the ground 3.69:1 putting my 66 MPH at a perfect 2,000 RPM and 82 MPH at a perfect 2,500 RPM but this drops my engine load considerable, EGT's drop, oil temperature drops, etc. MPG rises. More heat created anywhere is a lost of power into heat. 

 

My oil temp generally stays at or around 197°F. I have used 35x12.50, 265/75R17, and 295/70/R17, with little or no change in the temperature. I'm using the genuine adrenaline oil temperature sensor in the head of the oil filter housing. Is this a normal temp it should sit around? Could my oil cooler not be working efficiently?  I'll be switching to 245/70R17 tires here pretty soon.
