Tire pressure: What pressure do you run?

[FT86-guy]

Most people just take their tire pressure for granted. They don't realize it plays a big role on how their car handles as well as their gas mileage. Lowering your tire pressure increase grip but also decreases gas mileage. While increasing your tire pressure reduces grip but improves gas mileage. Just wondering what you guys use for tire pressure on your daily drivers? Personally I run 38 for my fronts and 42 for my rears on my rwd car. I found that I get pretty good gas mileage and also decent grip with that setup.

I put 36 on all four of my tires. Never tested to see if it made a difference in my mileage.

I also put it on 36 psi. The tire people alway try 28-32 but I think that just the comfy ride. Currently, I am very content with directional tires.

I drive my car in a normal way. I set the tire pressure at what ever is recommended by the owners manual. I figure they're smarter about these things than I am.

I like to run the pressure that will keep them rolling. usually the pressure that is posted on the side of the tires them selfs. I figure the manufacurer has obviosly spent some money testing to see what is best over all.

Run mine on what the label on the car door says - right around 32 PSI. Have had good results.

Those are the max tire pressure you are allowed to run. Very very bad idea to inflate your tires to those numbers.

You got the right idea. Bear in mind that those numbers are only recommended for stock tires. Once you change them you might need to adjust the pressure a bit. Either way 32 PSI is good for most passenger vehicle tires available today.

I will be making a point of checking the label on inside of my door to see what I should be running them at. stirke one on what I thought was common scence.

It completely depends on what tire I'm running at the time since each tire has different load capabilites that are somewhat independent of the vehicle/weight. In my FJ I run 60psi which is way, way over what is recommended inside the door. I'm doing it because I'm running an E-load range tire which requires more air pressure. In my wife's Accord, we're running 34 psi in the front and 32 in the rear as that has given me the most even wear results in the past with the same brand/size tires. I usually look at the tires as they start to wear and determine from there if I need more or less air. Most car tires range from 30-36 psi in normal operation I've found. If you run them at the max. recommended pressure, the tires will wear more in the center of the tire since it's like rolling around on an overinflated balloon.

The car has never been happier since I was playing with the pressures of the tires last week. Started with a little tiney bit over what was on the inside of my door and moved to a little less them what was there and the ride is very very nice now.

Set them to EXACTLY what is says on the door. That way you will get optimal handling, ride comfort and tire wear. The car companies do lots of testing to come up with these numbers. They are posted for a reason.

Now there is a man who knows something about tire pressures and load ratings. Keep in mind that if you use original equipment or comparable tires, the pressure listed on the inside of the door is optimal.
