New wheels and tires. What Preasure?

[98spyderboost]

Hey all. Just put on a set of 18" wheels & tires. They are H rated, does anyone have a good suggestion for preasure for every day driving?

 

[rdeterman]

each tire is different check the sidewall of the tire for the manufacture recommendations

not true,check inside youre driver door panel it will say what the eclipse is recomeended for.as long as you still have the basic size or compasated with low pros youll want to stick to man,specs.

I run 40psi if I want gas mileage and around 32psi if I want comfort.

you can check the recommended pressure as stated or run it at a different psi.

I agree with CanadianTSi, I run mine at around 40-41 for gas mileage, specially when I'm going to be making a road trip that is like 100 or more miles. I normally run 35 in the summer and 37 in the winter. I find that anything below 33-34 makes it too soft.

Eh. The door # is for manf. spec tires. If you go outside that relm the tire could dictate otherwise. Go with rdeterman, you can't go wrong with the tire manf. recommended number. Adjust to your liking.

This thread is pretty much useless, because what tire pressure you should run depends on lots of factors, including the tire's design and dimensions, the width of the wheel, the car's alignment, and what you want (e.g., lateral grip, longitudinal grip, gas mileage, and/or long wear). And these are not independent effects; you have to at least consider them all.

As an example, if you have an aggressive alignment (maybe for autocrossing), then you do not want to run high pressures, no matter how you feel about gas mileage, since you need the sidewalls to be soft or else say bye-bye to your tread, especially if you have wider wheels.
