Howard	How do most of you determine the correct tire pressure for your vehicles? The information listed below, suggest you use the manufactures placard located on the vehicle. Finding Your Vehicle's Recommended Tire Pressure and Load Limits Tire information placards and vehicle certification labels contain information on tires and load limits. These labels indicate the vehicle manufacturer's information including: Recommended tire size Recommended tire inflation pressure Vehicle capacity weight (VCW–the maximum occupant and cargo weight a vehicle is designed to carry) Front and rear gross axle weight ratings (GAWR– the maximum weight the axle systems are designed to carry). Both placards and certification labels are permanently attached to the vehicle door edge, door post, glove-box door, or inside of the trunk lid. You can also find the recommended tire pressure and load limit for your vehicle in the vehicle owner's manual
heynow14	Okay,,,,,,,,,,,,,Thanks I guess.
392HEMI	I think I use the easy method as most auto enthusiasts do. I first check the outside ambient air temperature, subtract the average pavement temp.,where I will be driving, add back the pressure build up variant at the expected average speed I want to travel, add the manufacturers maximum air pressure from the sidewall of the tires to that, multiply by pie - R - squared ( an oxymoron if you ask me ) and divide by the diameter of the average size rim on the vehicle. This method is quick and accurate and can be constantly checked by your onboard computer between your ears to adjust to changing conditions as you drive and help offset dreaded driver boredom caused by endless miles of traffic jams and gridlock. The informed driver will always check for the "low tire light" to verify his instantaneous calculations and listen carefully for the also dreaded earth shattering blast from an expanding carcass that can no longer hold its average air pressure intact. This is it in a nutshell. At the end of the day, a quick visual check will tell you if your tires are in the shape you wish you were in, UP!!
Tytanium-K	I always put 35 psi in all mine...Prowler, F-150, PT Cruiser...seems to be relatively universal unless you have a very unusual tire/vehicle...like a tractor or whatever!
Kraut	The sticker on the B-Pillar calls for 28 front and 32 rear. Unfortunately, it rides worse than my F-350 at 26 PSI, which is about 2 PSI over the pressure sensor settings. It takes that much to keep the sensors from constantly turning the light on. I really don't think you need any air in the tires to keep these runflats up and running. The concrete sidewalls make them feel like solid tires. ------------------

toys	28PSI front & rear. Toys
dbudner	I use the same amount as I do in my flintstone mobile. Keeps the ride consistent...
KOL CAT	28 PSI FRONT & REAR Kol Cat, Gene
392HEMI	I don't think he asked how much air we think is in the tires, he asked what method we used to assure there is correct tire pressure. I checked with my dad and he used to kick the tires and if his ingrown nails killed him they had enough air, if the re-cap blew off they were underinflated. Now in the Cat's I use 28 pounds, per label in drivers door frame which seems to be much softer than 35 especially on the highway.
wuzzzer	For most passenger cars the rule of thumb I heard was you're safe to go 1 PSI for every 100 pounds the car weighs. 2800lbs=28 PSI, 3500lbs=35 PSI, etc.
