YACT: What is considered normal tire pressure?

[SCSIfreek]

Hello all Car gurus,

I was just wondering what's the normal tire prssure for mid-size cars such as a HONDA civic, accrod, Toyota camry,etc..

Just a guess 32 Psi?


Thanks,

Scsi

Depends on the car and type of tires. Look on the door jam of the drives side door.

 

[GroundZero]

depends on the tires you have the recomended psi is on the sidewall of the tire.
go by what it says there and not by the car doorjamb.

Thanks minendo,

I'm a moron when it comes to cars.

many times I find the recommended psi seems a bit low.

the car manufacturer doesn't necessarily know what brand of tires is on your car. as someone who sold tires for several years, take my word on it and use the tire manufacturers recomended pressure. it will give you the best performance and life for the tires you have.
too much pressure and you get more wear in the center of your tread, and too little pressure you will get outside wear and possible sidewall damage.

Thank you Thank you.

also take note.. too much pressure will change what is known as the "contact patch" with the surface of the road..

Follow the manufacturers recommendations.

I also agree that the pressure should be set to what the TIRE says. The doorjam pressure is what the pressure should be for original tires for the car.

I replaced the stock tires on my car with Dunlops. The recommended tire pressure is 30 psi front, and 26 psi rear. (No, I don't drive an Explorer.) While those pressures seem low, and I can get better gas mileage by running them at 33 psi, the car handles best at the pressure recommended in the door jamb.

That's my $.02.

Uh, the pressure listed on a tire's sidewall is NOT the recommended pressure, it's the tire's MAXIMUM pressure. Note that it's the absolute maximum and not the cold maximum. If a tire says 40 PSI, then the tire should never exceed 40 PSI, even when the tire is hot after driving a long distance at high speed. The manufacturer's recommended pressures are cold pressures, you should make sure that the car has set for a while before checking the pressures. Pressures can increase by as much as 5 PSI after driving.

EDIT: My last car recommended 26 PSI all around, current car is 30 PSI front and 36 PSI rear.

Was you first car a Explorer? And the second a 2WD Ford Truck?

 

[Evadman]

55 PSI front 80 psi rear.

My first car was a 1988 Honda Accord, second is a 1987 Porsche 924S. My father's Explorer is 30 PSI front and 32 PSI rear IIRC (been a long time since I've driven it).

Sounds like my friend's E-250. Those SteelTeks sure don't "soak up the bumps".

I have found that the cars I work on in Wil. NC do very well at 36 front and 32 rear. I like more up front as it keeps the tires from wearing on the sides to much and a lot of tire places will void the warrenty if they see to much wear on the side. But those numbers and roattaing them every 6-7.5K wears them very even.

 

[SCSIfreek]

Ok, now I'm all confused. I just check the Manufacture's recommended pressure, It only say never to exceed MAX 44psi. nothing referring to a recommended pressure. then I check the doorjamb, it says 30Psi all around. oh by the way this is from a 2002 Honda Accord.

[Vortex22]

Fill it to 30 psi then.

Wild guess: 235/85R16, E load range?

 

[m2kewl]

If you're replacing tires, you should follow the tire manufacture specs. i.e: michelin mx4 tires on my civic and i have 'em at 35psi.

edit: i stand corrected - follow the owner's manual (says 32psi for me)

go by what it says there and not by the car doorjamb.

uhh that is huge misinformation. the psi on the sidewall is MAXIMUM pressure, not recommended. ALWAYS go with what the manufactuer says on the doorjam or in the manual..

NO NO NO NO NO, as stated in several posts above, that is the Maximum.

The the correct tire pressure for your car would 30 psi cold, which means not driven on for at least 3 hours.
