Tire Pressures
Soo, I have been running for about a month with 45Lbs. front and 40Lbs. rear pressure on my Fit after having read here somebody doing it. This weekend I brought the pressures down to 35Lbs. front and 30Lbs. rear and went out driving, I think am going to leave them there. With the higher pressures I was hoping to get better gas mileage but let me tell you, every time it hit a bump, it would feel like solid rubber tires not only that but the wind would throw the car off course very easily. Now it feels more stable and stays on course.

Just a couple other threads that this has been discussed similar to this.

Yeah, tell me about it, any little road imperfection was felt really hard not to mention real bumps. I always run the pressures a little higher to compensate for air pressure loss between checking and refilling but I had never ran them as high as some members here.

Now, why do you have to start insulting people for no reason. This forum is for us to write whatever without fear of predators like you insulting us. You should apply Lincolns quote to yourself.

I am also constantly experimenting with tire pressures. I prefer to keep the tires in the 40ies. I honestly believe I get better mpg and driving just feels better and more sporty to me then when I keep them at 32.

yeah, but experimenting with tire pressure is good for getting driver feed-back from the car, and therefore people are learning how it can and does affect the driving quality and performance. I would have no problem with going with Honda's rec., but experimenting with a reasonable amount of increase/decrease is a great experience for drivers to see how the car handle and performs with such increases/decreases.

Manufacturers recommend tire pressures for a number of different reasons. Not all of them are for the best performance or mileage. Often it is for ride smoothness. In my case, the 36 psi gives even wear, better handling and good mileage. Good enough for me on both my Solstice and Fit. My CR-V gets lower pressure. Blindly following a car manufacturers numbers for everything does not always give the best results, from tire wear, mileage or engine life.

As I've said before. Set them to the recommended pressures. Run them for a while then get yourself a tread depth gauge and measure the tire wear. Adjust the pressures (More pressure if edge tread is more worn or less pressure if the center tread is more worn) so that the tires wear evenly.

As others have said, manufacturer recommendations are compromises made to weigh multiple factors. In addition to ride comfort, gas mileage, handling, and tire wear, we also have to add simplicity for simple-minded consumers. Neither the door jam nor manual details adding pressure for additional load. The load capacity of the Fit is 850 lbs. Ideally you should probably add a few PSI of tire pressure for each say 200 pounds of additional cargo weight (including passengers). But that's too complicated for the average consumer to mess with. So one number on the door jamb is a good compromise, but it's not necessarily the "best" depending on what the goal or conditions are.
