Michelin's Recommendations on Tire PSI
Check Pressure Once a Month
?It?s possible for a passenger tire initially inflated to 35 psi (pounds per square inch) to lose 1 psi each month.
?Be sure to properly check all four tires ?cold? once a month and before a long trip.
?Whether you have a full-size or mini spare, make sure that it is properly inflated as well.
.Recommended Pressure
If you don?t know the proper inflation air pressure for your tires, what do you do?
Easy. Check at one of the following places on your vehicle:
?In the vehicle owners manual.
?On the vehicle?s door jamb. (Often, a vehicle information placard is located on the door jamb along with the recommended tire inflation pressure.)
?Inside the fuel hatch filler flap. (In some vehicles.)
?The glove compartment door. (In some vehicles.)
?But NOT on the tire. The inflation pressure shown on the tire sidewall is only the maximum tire inflation pressure. In most situations, the vehicle manufacturers recommended tire inflation pressure is shown on the vehicle placard. However, on some older vehicles, the recommended pressure listed by your vehicle?s manufacturer may be shown as two numbers: One for city speed driving and normal load and one for highway speeds and/or maximum capacity vehicle load. Be sure to inflate your tires to the recommended inflation pressure for each type of driving situation.
How to Properly Check Tire Pressure
1.Beware of public pressure gauges at gas stations. They are often abused and unreliable.
2.Purchase a good pressure gauge and check it for accuracy with your Michelin retailer.
3.Check your tires ?cold? ? before you?ve driven even one mile or at least three hours after the vehicle has been stopped.
Inflation Tips
1.Air expands when it?s hot and contracts when it?s cold
2.It?s best to inflate your tires in the morning before the day?s heat.
Valves and Valve Caps
When it comes to proper tire pressure, the tire?s valve is a very important maintenance item. Valves are ordinarily made of rubber, so they can deteriorate over time. Replace them when you buy new tires. At high speeds, a cracked, deteriorated rubber valve stem can bend from centrifugal force and allow air loss.
The valve cap is also an important item. Buy high-quality valve caps that can help contain the tire?s air, should the core of the valve fail for any reason. Valve caps also keep out moisture, which could freeze and in turn depress the valve core, causing air loss. The cap also keeps out dust and dirt particles, which could also interfere with the proper operation of the valve core and cause air loss.

question then: what's the best PSI to have your tires at, for gas mileage, if they recommend 32?

You people that inflate to the sidewall max need to DIAF and stay the fuck off the roads my family and I are on.
This has got to be a joke thread . . . .

The best for gas mileage is max. Less than that gives better traction, and a softer ride.

no, it is not a joke.
the op has also stated that he wont buy a car with a sunroof because the extra weight would ruin his gas mileage.

Intentionally over-inflating your tires with the knowledge that it decreases traction (and thus safety in some situations) is pretty fucking stupid and selfish.

You're not overinflating if your at max or less. The car manufacturers specify a lower than max inflation for the softer ride, that's it. I've put more miles on the road than probably everybody in this thread. From cruising at 90mph, to driving on cobbles in the city, to creating trails through the woods, and I've had 0 problems with my traction....

I thought I was posting in the garage but it's ok because I do benefit from having a different audience to post to.
Except that crossposting is against forums rules.

And how many miles would that be?

Incredibly ignorant statement.
It has nothing to do with a "softer ride" it's for the best, most efficient tire cotact patch, promoting the best stopping distances and overall traction, and for the best wear/longest tire life.
This thread + the one asking if guys change tires has greatly reduced the testosterone that once ruled these forums.
The pussification of Amerikka continues.
I have to give it to the OP - he is a master troll.

That's crazy talk. I can feel a difference in traction/handling/steering/etc from being 5 psi under my manufacturers recommendation, and being at their recommended pressure. I have a very hard time believing that I wouldn't notice any difference if I went another 5, 10, 15, 20, etc PSI up.

The tire's rating trumps the manufacturers rating. What if you put light truck tires on your vehicle? Typical max for a passenger tire is 35psi. Typical max for a light truck tire is >60psi. If you inflate that 60psi tire to the manufacturers 35, it has a good chance of peeling apart after driving awhile, especially at highway speeds.; I've seen it happen....

Unfortunately, common sense and logic need not apply to these people. They'd rather have their tires get frayed and blow out prematurely than dare go against what the car manufacturer recommends. If these people were up on a canyon road and there was a sign that said turn right but there is no where to turn right on to, they'd turn right anyway and would promptly fall of the road.
