Default Tire pressure - door sticker or tire sidwall?

They are 10 pounds different from each other. I know lowering the pressure to what the door says would soften the ride a bit, but would it be better for the tires at 44 lbs like they state?

44 lbs seems a tad high, if you go too high you will wear the center of the tire out, the outside edges will not wear much, and some traction with the tires will be lost... I run mine a bit higher th likan the door states,e 36-38 psi IIRC only cause I like the ride and the trailer I pull rides nice when I am hooked to it.

I run 40 psi. I go by the tires. If you have the right tires, they are rated for your application. I believe the people making the tires know them better than the vehicle manufacturer. Though there are people that believe the other way around.

The tire side wall if read correctly states MAX P.S.I.. You should use the door label for normal driving.

Correct! (though I do run them about 38psi instead of the 35 on the door)

I personally follow what is on the sidewall for *all* my vehicles...

The vehicle manufacturer will give you the psi they want to make the ride more comfy...not necessarily what is best for the tire...

Example: The recommended tire pressure for my Valkyrie from Honda was 30-35psi (IIRC), while Dunlop recommended 40 psi...so what happened is that a lot of folks who ran their tires at the lower pressure hsd their tires delaminating and creating bubbles on the carcass...not bueno on a bike...

I guess I will try right down the middle. I've been running 44. I wonder if there will be any noticeable difference at 38..

possible slight. Softer turns, less MPG, softer ride, better traction, but so slight you may not notice.

I ran a set at 44 pSI and quickly wore the center of the tire out. I did pick up some fuel miles. I believe it was only .5 miles per gallon better.

NO, NO, NO!

psi on the side wall, is only a maximum rating the tire will handel in a max load/temperature condition with out exploding... and if you run higher load rating tires, the psi rating on them con get up to 80psi. the biggest thing it comes down to is, if you run to much psi, it will wear the center out of the tires, but that is because it pushes the center of the tire out, giving you a severly lessened contact patch on the road, now put in some bad conditions, (rain, snow, ice, basically anything other than dry pavement) the the rear of the vehical is going to want to pass the front very easy, not to mention the effect it will have on braking, but run to less of a psi, it will wear the edges of the tires, but also will give you a lot of sidewall flex, and if weight is added, like a load in the back, that extra sidewall flex will cause a lot of heat and too much the tire will come apart too, basically tou need to run the correct psi for the weight of the vehical, and the width of the tire, if you are using a stock width tire, the psi in the door (or close to it)is your best bet, for traction, ride and mpg's
