[ARCHIVED THREAD] - Tire Pressure Question

Posted: 8/31/2005 2:43:42 PM EDT

In these days of ruinous gasoline costs one must do whatever is necessary to save a few bucks in gas. I noted that the Chrysler reccommended tire pressure for my car is 35 psi cold. The tire has a listing of 44 psi max.

So the question is: Should I stick with the list 35 psi or jack it up to 44 psi? Which would get me better fuel economy?

Chrysler didn't design your tire, go with what the tire says

The manager of the muffler shop that I went to recently said that the higher pressure is correct (at least on my car). I put it up to 45 doesn't seem to make any real difference that I can tell.

Wrong. Chrystler did design the car, and therefore the weight and weight distribution on the tires. Always follow manufacturers recomedations.

My car is suposed to be inflated to 29psi, andI have max 52psi tires on the car. If I follow the tire that car would handle horrible and the tires would wear completly in the middle only. Tire pressure is designed to keep the tires with the proper footprint.

I have a Dodge Ram 2500 CTD and I run 55 in the front and 45 in the rear even though the tires rate up to 80. For an empty truck, 80 psi makes the tires wear too fast in the center of the tread.

Hell, just jack it up to about 100 psi with helium and double your gas milage!!

What you save in gas by reducing resistance by max inflation will be eaten up by excessive tire wear.

The tire manufacturer didn't design the rest of the car that rides on that tire.

Notice... it's a max pressure, not a recommended pressure.

However, I wouldn't have less than 80% of the max press. in the tire. Less than 80% and it's considered flat by the tire industy.

Maximum pressure is for the maximum load for which the tire is rated.

Radial tires run at lower pressures.

Use some sense.

Go with the vehicle recomendations, not the tire. My Chevy says 30 psi but the tires say 50 max. At 50 the thing rides like crap and handles worse. I know I can't spell.
