I was just wondering how much air you guys put in your tires.

Here are mine:

Car: 2002 Nissan Maxima
Tires: Falken Ziex 912
Front pres.: 40 psi
Rear pres.: 36.5

And if you have a reason for the numbers you use, post that too.
 
2000 Maxima, Bridgestone Turanza Serenity, 215/55R16 f36 r33

2007 Silverado, Toyo Open Country H/T 275/65R17 f38 r38

I tend to run 3 psi over factory recommended pressure and get excellent wear and handling, and not too harsh of a ride.
 
2002 530i: Bridgestone RE960, 29 PSI front, 33 PSI rear

This is the factory recommended PSI at half load. When I tried running higher pressures, the centers of tires would wear out prematurely.


2001 Jetta: Bridgestoe RE960, 29 PSI front, 29 PSI rear

I think the factory recommends 26 PSI all around. I inflate them slightly higher because I don't want it to be too low if the outside temperature drops, and I don't check the pressures on it too often since I don't drive it.
 
2005 Toyota Camry
15 inch Yokohammmmmas AVID TRZ's
30 front 30 back.
Book calls for 29 f& b.
I put 32 in and car gets to roaming.....34 forget it.

I had Kelly Navi Gold on before and ran 34 f&b.....it road alot smoother on those tires.

08 Jeep Liberty: Goodyear Fortera 40 psi front and rear.
93 Aerostar: Firestone Indy 500 40 psi front and rear.
88 E-150 Goodyear Fortera 38 psi front and rear.
 
2007 Mazda3
Factory terrible Goodyear Eagle RS-A
Front Pressure: 39.5 psi
Rear Pressure: 37.5 psi

Overall, the car feels better. Braking, wet grip, ride, fuel econ, acceleration, handling, etc. I can't wait to replace these tires, they suck.

Yes, they certainly do.

On the Mazda:
General Altimax HP 215/50/17
35 front
32 rear

On the Ford:
Bridgestone Dueler HL Alenza 245/65/17
35 front & rear
 
2006 Honda Ridgeline.

Owner's manual calls for 32 psi front and rear. I have tried filling to 36 psi, but the ride gets too rough. I never saw a change in the gas mileage running them this high.

The thing we all have to be aware of is, in the colder months, we have to check the air pressure more often.
 
31x10.5x15 on the Jeep I run 26 and they still wear more in the middle. Any lower and mpg takes a big hit.

33x12.5x15 on my pickup.

25 front and 18 rear. Rears are almost bald in the middle even @ 18psi!
 
32 PSI all around. It seems to give the best compromise of fuel economy, driving and steering response, and ride comfort.
 
'94 Lexus LS400: Plascard: 32 F/R. Actual 36 F/R
'00 MB E430: Plascard: 32 F/ 33 R. Actual 36 F/ 38 R
'04 Honda S2000: : Plascard: 32 F/R. Actual 34 F/ 32 R

When I go on long trip in the MB E430, I pumped the pressure to 40 F and 44 R.
 
2008 Honda Civic EX Coupe
Michelin HydroEdge
Front Pressure: 42 psi (32 psi recommended)
Rear Pressure: 40 psi (32 psi recommended)

I increased the pressure a bit to get crisper cornering and more feedback from the road.
 
04 saab 9-3 is specced at 41 front, 38 rear, so I keep it at that.

My MB and BMW were both rated at 28 front, 32 rear, and I bump each up by about 4 psi on each wheel.

I generally bump all our tires (including bicycle) up by about 4-6 psi.

On our rabbit, I use the same as the saab - 41 front, 38 rear, though it is specced at 32 all around, as I recall. It probably helps with fuel economy.
 
2000 F-350 DRW Michelin LTX M/S 60 PSI front 58 PSI Rear

Featherlite 4 horse trailer LT235/85R16 Michelin XPS RIB 65 PSI

Walton 16' tilt deck trailer LT235/85R16 Michelin XPS RIB 65 PSI

2008 Bloomer 6 horse 235/75R17.5 Michelin XTA2 110 PSI

2006 Kenworth T-800

Michelin XZY3 425/65R22.5 Heavy loads 120psi fronts (Normal days 105 PSI) (22,000 LB rated axle)

Drive axle Michelin XDY-2 11R24.5 120 PSI (52,000 rated tandem axles)

Murray "16 tire professional" 16X Continental HTR 215/75R17.5 125 psi. 16 tires across "1 axle group" carry 60,000 lbs.
 
1999 Buick LeSabre, Pirelli P4.

Placard is 30 psi, tire sidewall 44 psi.

Pressure: 44 psi front, 40 psi rear.

I like having the tire not roll onto the sidewall during turns, and like the extra sharpness the higher pressure provides. Can't stand the boat-y, disconnected feeling of the tires at 30 psi. Also slightly better fuel economy.
 
1996 Saturn SL2

Front: 30 psi (recommended)
Rear: 26 psi (recommended)

Michelin Hydroedge tires. The new struts are too harsh/firm to use anything more than the recommended pressure.

1992 Toyota Previa

Front: 38 psi (35 psi recommended)
Rear: 38 psi (35 psi recommended)

Michelin X-Radial tires.
 
2007 F250 Powerstroke with 4" lift running 325/60R20 Toyo Open Country ATs. Front: 48psi; Rear: 43psi when not towing; 48 psi when towing. The center wears quickly on the rears when running more pressure. I could probably drop the rears even more for daily driving, but I'm a bit hesitant, don't want too little air in them & 43psi doesn't seem like enough in such a heavy truck.
 
2003 Mazda Protege5, std size 195/50-16 Kumho ASX. Spec 32 psi front and rear, with no mention of increase with load. I run 38 in front, 32-34 rear (empty/loaded). No problems. If I run just a bit more pressure in the front, it changes over to slightly stiff/bouncy/feel-the-pebbles. Wearing well with 5K-6K rotations.
What's odd, is that my 1999 Mazda 626 specs 32 front, 26 rear, with the same 60/40 weight distribution. Then again, the 626 wears old school 185/70-14's.
 
Sad to say but too many vehicles, most of which are not using factory tire sizes, get standardized air pressure. Trucks get 50 lbs, cars get 32 lbs. Trailers get 65 lbs. The only change is if I'm towing heavy with the trucks.
