Man, I've been getting sucky mileage lately and can't understand why. The only two things I can think of are the tire pressure which may have changed or that I put in my TEIN HA's.

Does anyone know the correct tire pressure (cold) for the GS4's with 16 stock (soon to be changed)? Everyone seems to have a different opinion.

My driving style hasn't changed, but I'm losing like 2 miles per gallon every fill up.

kevs,

I don't think lowering the car will cause your gas mileage to go down. If you want the exact tire pressure you should set your tires at, just check the sticker inside the driver side door.

Your car might just need a tune-up, or it could be after you lowered your car, you might be taking just taking the corners harder punching the pedal more making you use more gas. Dunno?

Look on the side of your door jam. That's the recommended PSI for comfort/fuel economy.

Pump a bit more if you want a bit more handling.

For my setup i'm told from the alignment shop to run 40PSI for the front and 35 PSI for the rear.. granted i have 40 series in the front and 35 series in the rear.. known as fat tire setup.. FOr stock 16's i'm thinking between 35-40 PSI?

34 all around with 18' offset rear

Lets be honest, you've got a heavy foot and it got a bit heavier when you added the new suspension. 34-35 psi should do. Running the pressure too high will only ware your stock tires prematurely. They are not designed to run sucha high tire pressure.

For stockies, I used to put in 35 psi all around. Too much air, and you get premature tire wear in the middle, plus a bumpy/skippy ride. Too little air, and you get premature tire wear on the outsides of the tire, plus lower gas mileage, decreased handling and decreased acceleration.

For my 19's on Falken Azenis, I use 38 psi all the way around.

I run 16" Michelin Pilot Sport A/S and the recommended pressure for them is 32 psi.

Is this thread really from 02? If it is, by now its probably his O2 sensors.
