Tire Deflators
I know they are generally used to air down for additional traction off road, and most have an adjustability range of like 10-30 or 40 PSI, which is too low for my purposes.
I have my tires at 60/65 F/R per Ford's recommended when towing or loaded, but like 48-50 driving around empty for comfort. It's a real pain to stand there holding the valve open to lose 15 PSI.
I found that Staun (presumably the standard bearer of deflators) has one that does 15-55 PSI. So I got them and set them up per the instructions, for 48 PSI. However, two of my tires ended up at 37 and 41 PSI. Am I asking too much precision from these?

Yes. Thats too much to ask. Set the Staums for 25psi and toss them in the glove box for a muddier day.
Get a Morrflate manifold for street settings. Deflate all four at once. If you run higher psi in the front, deflate all four to that psi, then disconnect the front, and deflate the rears further.

Ive been running same pressure front and rear on SRW, to reduce understeer in the wet. I could go much lower in the rear.
Regardless of guage accuracy, at least a manifold will have perfect left to right pressure. But.........................is that even something we want? For me, its fine.
