Yup that gave me a much better idea. I'm gonna toy with some different PSI's to see if I can maybe feel a difference in my ride (doubt it, but oh well). Thanks!Originally posted by andybob View PostWhen automakers put those recommendations on the door, they take into the weight of the car, tire size, and probably a bunch of other crazy stuff. Those pressures on the inside of the door are for stock wheels and tires. Engineers determine them so you could a good ride with even tire wear, gas mileage, etc...
Now, with that said, run whatever you're comfortable with. I'm assuming you have some decent fitment and running a smidge or so of negative camber, which is going to wear the tire differently than a stock suspension/tire combo as it is, so it doesn't really hurt to go above those number.
I run at 45 with the hope if I hit an astray pothole or something the wheels won't be damaged. That's just me though. Some people run a higher PSI if they are running a lot of stretch, it helps keep the beads sealed.
Reading through that I kinda rambled, but I hope that helps you out.
