How much air do you keep in your tires?

[Ducaire]

On my tires, it has "Max Pressure 44 Psi" printed on the tire, so I keep 42 pounds of air in it just to be safe. How much do you think I should put in it if I want the best possible mileage but at the same time don't run the risk of having a blowout? (With the way I drive, it's mostly highway miles, I don't do any towing, and I don't slam on the brake and gas so I'm not wearing my tires out).

Lot of different kinds of tires.
42 sounds like a lot of pressure for a regular S-10.
It is better to check with your favorite shop or go with the tire manufactures specs.
Unless you are carrying a heavy load I would not think you would need to go the max pressure.

35psi is what most run. on the drivers door it says either 32 or 35.

The reason it has 32 psi on the door is so that the vehicle will ride smoother. (It rides smoother over bumps if you have less air in the tires). The manufactorers put that so the vehicle will attract attention. Really you can add more.

I have typically used the max pressure listed on the sidewall; the vehicle makers spec is a concession to ride quality and is probably on the low end of the tire manufacturers range for normal operation..... ever wonder why there is no rating for minimum tire pressure???...... The higher pressure will result in a bit firmer ride but will typically tighten up the steering response a bit and maybe increase your mileage a smidge. Most big chain tire shops will tell you to use the manufacturers pressures.... but I think this is more the corporate liability lawyers speaking here. As long as you do not exceed a tire's max inflation pressure, you need not worry about them "blowing out".... quite the opposite occurs; if you run your tires underinflated long enough, they will run hotter and eventually the tire will fail...often very catastrophically.

i would keep them between 30 and 35 psi i work at a dealership in the service center and the only vehicles we set higher than that are the heavy duty tires with like class e tires if you inflate your tires higher that that your going to have your tires wearing on the inside tread and not on the outside causing your tires to wear out faster. also depends... what size tire are they, and are they an A/T, all season?. either way, no higher that 35.

Thats funny...your profile says you work at BEST BUY

The Certification/Tire label is found on the driver's door edge, above the door latch. The label shows the size of your original tires and the inflation pressures needed to obtain the gross weight capacity of your vehicle.

According to his my space account, he worked at Best Buy from September 2005 - September 2006. It says that he's been an intern at the dealership for 6 weeks. It also shows that he's going to a technical college and his major is GM ASEP.

I believe him, but can appreciate your skepticism, we get way too many people on here claiming to work in the automotive repair industry.

Too many self proclaimed experts around here.
Funny part is brandon200317 is the only one who responded when I called him out about working at a dealer...the rest ran and hid.
So brandon200317 I do apologize and wish you the best in your ASEP program.

WELL...........I don't work at a dealership but I do know it ALL! Everything there is to know,just ask my wife,she'll tell you I know everything.UHHHHH.I have turned wrenches in the backyard for at least,2 maybe 3 days top's. I run 29 in tires.245/60's.

[hotrod_chevyz]

I keep 40-42 PSI in front and 38-40 PSI in back. Any lower than that i wear out the sides of the tires and ruin my raised white lettering. Rides a little rough, but handles way better than 35 or below. I cant stand how a car feels with 35 PSI or below its annoying.
