How much pressure do you like in your tires?

I'm curious how others decide how much air pressure they want in their tires. The tire states a maximum pressure on it. How close to that amount do you like to be?

Yes use what the tires say to use.

My tires ask for 65 pounds of pressure, but I find the ride at that high of a rate too hard, so I drop em down to around 50 pounds.....

"These are special tires, made by Sandoz Laboratories. Hell, you could pump 'em up to 90 psi."

I like enough pressure that my gas mileage doesn't go down, but not quite enough to cause me to have a blowout on the Kansas Turnpike and take two or three other cars with me into the afterlife.

The max pressure should *never* be used. Always go by what the door plate states is the proper pressure for the vehicle (if you have the factory recommeded tire size) You can go about 2psi per tire higher if you want a slightly firmer ride, don't go lower unless you are trying to get traction in snow/mud/sand and the situation is low speed.

If you are a real performance nut, you can ponder this for a bit

(Vehicle Weight in lb/100) + 2 psi at heavier end + 2 psi all around if suspension and alignment are stock.

Example: Stock Porche 911, 3,000 lb.
(3000/100) = 30 psi
Add 2 psi all around = 32 psi
Add 2 psi to heavy end = 34 psi at rear
With modified suspension, the result is 30 psi front, 32 psi rear.

There is no 'golden' tire pressure. The optimal setting depends on the individual driver, the car, and driver's preferences.

I blow them up to 3,405 psi and then just never fill them up again.

Between 18 and 55psi.. depending on the tire. Seriously.

This weekend, it will be 18psi on Goodyear racing slicks.

I heard the recommended tire pressure on door is if you use OEM tires. If you use another brand, it will vary. True?

I have to confess that after all of these years of driving many different vehicles, I never noticed that there was a recommended tire pressure on the door. I've always just used whatever felt right below the max pressure stated on the tire. I'm going to go check mine and see what it says. I've been running about 36 psi on a tire with a 44 max. I wonder how close I am to the door sticker.

I just checked the sticker and it recommended 33 cold. I was over by 3 but it feels pretty good that way.

Hey how do fix a "slow leak" problem. Having to go to the garage every two days to put air in (two of) my tires is a pain in the ass.

If you're having to fill air every two days, the leak is substantial. bring it to a tire place, and they should be able to find the leak and patch it.

1. get a spray bottle
b fill with water and some liquid soap
c spray onto tred of tire if you see bubbles then that's the leak
2 buy hole plugs, they look like black licorice(about 4 inches long) and there's a thign that you use to put them into the hole, follow direction on the package

or
spray the soapy water around the rim, I once had a leaking tire which was from a rock gettign between the rim and the tire itself

NOTE: if the leak is from a hole in the tire wall then you're SOL and will have to buy a new tire

Regardless of brand, it's best to use the recommended cold tire pressure on the sticker the car manufacturer mounts (usually) on the door of my car. That's why I use 30 psi front and 29 psi rear on my 1998 Civic HX CVT coupé.

That's if the tires are the same size as the OEM tires, or very close to the same size. If they are radically different, you're on your own in terms of tire pressure.

back in the late 1990's people listened to Ford's numbers and a bunch of Explorers flipped over. Many manufacturers take other things other than safety when making up those numbers. Tire manufacturers usually look only at safety.
