Tire Pressure

[FreshBubble]

What PSI do yall fill your tires up to?

[HLandin]

Set it to the recommended amount. The sticker on the driver's side door says 35 PSI. You could also check in you owner's manual. The important thing is what the max rating for the tire is because the air will heat up and expand while driving. You don't want to exceed the rating of your tires (mine are 44 PSI max) found on the tires themselves.

I usually run mine between 32 and 36 PSI, depending on the make of the tire.

Depends on what the TIRE maker says.

I wouldn't go by the sticker on the door. Does anyone remember what happened with Ford Explorers and Firestone tires???

Ford said to user a lower pressure than Firestone did. Bad things happened.

Exactly.

The stickers on the door are valid for the ORIGINAL EQUIPMENT TIRES ONLY, in MOST cases, unless of course you're Ford. In that deal, Firestone recommended 32PSI, Ford recommended 24PSI (for a better ride, according to Ford).

I run my '84 wagon between 32-34 all around.

would someone PLEASE go over to the ENG/TECHNICAL forum and look in the tire pressure thread. those people are contradicting this exact thing...

Let them fill their tires as they see fit.Those guys sound like they are clutching at their chest with both hands and sticking one leg outta bed. They have a fairly clear understanding of 1975 tire technology and refuse to ackowledge the improvements that TIRE manufactures are continuosly making every day.

I pretty sure that none of the major TIRE manufactures will be consulting these guys asking for their recomendations on tire inflation any time soon.

Thirty years ago American cars weighed 4-6,000lbs and all tires said 28-32 lbs max inflation on the sidewall. Todays cars weigh around 3,000 lbs and in many cases have much wider tires than the typical 70's auto. There has been a trend of gradually increasing tire inflation recomendations by TIRE manufactures over the past 30 years. Now we have tires that say 44lbs max PSI on them on realetivly light weight vehicles. Tire pressures are cold and should not be adjusted as heat increases tire pressure.

Modern automobile tires are far more sophisticated than comparing them to an illustrative example of a party balloon having limited structure. Modern technology of tire construction continues to reduce irregular tire wear problems that over years past were blamed totally on tire inflation. Engineers who design tires are blending construction and inflation together to develope and produce longer lasting, safer, and more fuel efficient tires. Before a tire design ever leaves the computer drawing board, the engineers know what the tire should do at the tire pressure it has been designed to work at.

If your tires are the size recommended by the AUTO manufacture, the max tire pressure molded into the side wall by the TIRE manufacture will not create a liability to them or cause the tire to dervolope undisirable characteristics, contact patch, or otherwise reduce safety.

Well said!
