Just kinda a quick survey my hse7 d2 2002 says 28psi in the front and i was wondering what the perks of running it that low i have all 4 tires at 35psi because i heard that helps fuel economy but i dont believe that honestly

 

Perks include a better ride generally, more comfortable. Higher PSI will definitely get you better MPGs as there's less resistance. Depends greatly on what tires you're running though.

 

i avg about 12 mpg would lowering them down to 28 hurt that at all or is it negligible

 

Most people here agree that 40 psi all around is the best pressure. 28 psi on the front causes the steering to be heavier.

 

I run at 26 all around, Km2s though so they hold their shape. I would run 32psi personally.

 

30 front-40 rear for me, but curious to see what the consensus is

 

I got 255/55/18 Goodyear wrangler HP I run at just under the max 45 psi 50 is max if the pressure gets lower than 40 my mpg is heavily affected!! And still my rolling resistance is very high for some reason.

 

40 front/ 44 rear

 

26 pounds, that is crazy and a terrible thing to suggest to someone who is looking for dependiable information.
If you are running 16" tires, it is 40 pounds all the way around, if 18' tires around 37 or 38 pounds.
26 pounds will give you terrible gas mileage and wear out your tires way too soon.

 

Also, always run the same air pressure front and rear for less wear on your power train, especially if you are using your CDL.
