How inflated should you keep your car's tires?

Question

The tire says it has a maximum of 44 psi. Should I inflate it until it's at that point or should I keep it at less than that? Also, what pressure would be too low?

Answer 1

Its the MAXIMUM your tires can handle, anything ABOVE that will cause a blowout. Standard tire pressure when its COLD should be 32-36PSI.

Answer 2

I am a ASE Certified Automotive Service Advisor with 5 years experience in the tire industry. I cringe every time someone asks this question because they invariably get bombarded by tons of really bad answers, just like you have. So here is the long and short of tire pressure recommendations.

The sidewall of the tire DOES NOT give a recommended tire pressure. It tells you how much weight the tire can carry when inflated to its maximum pressure. That is all. The air in the tire is what carries the weight of the vehicle. The more air, the more weight the tire can support - up to a point. A tire then is essentially just a container for air. Since the tires on your car might fit dozens of different vehicles, not just your model, and all with different characteristics, it is up to the people who made your car to determine what the best pressure is for running that tire on your vehicle.

Inflate your tires to what the car manufacturer says they should be inflated to. This information, like just about every other question you might have about your car, can be found in your owners manual. Barring that, it should also be on a placard on the drivers side front door jamb. The car manufacturer works with the tire manufacturer, spending months of testing and hundreds of thousands if not millions of dollars of development work and testing to find out exactly what the best pressure is for that tire on your particular vehicle. That same tire on a different vehicle might require completely different pressures. All the other morons here are just guessing or passing on really bad myths.

Answer 3

The correct tire pressure is whatever the manufacturer recommends often the rear and front tires are inflated with different pressures, check the manual or sticker in the glove box, inside door, door jamb or on the fuel filler door. Most car tire pressures range between 28-36 psi.

Answer 4

what type of vehicle are we talking about ? if the tires say 45 max that means with a full load in car and trunk, on average a car should be inflated to between 32 psi and 35 psi for a comfortable ride same rule applies to trucks just a slightly higher psi

Answer 5

examine your handbook. ideal tire stress makes your automobile take care of precise and minimizes friction with the line. If the full usa endeavoured to do small issues to decrease potential use we would be saving a minimum of three% each and each year. individuals are quite often way out of shape. they might desire to learn how to stroll or holiday a motorbike not in basic terms interior the interest of saving gasoline yet to maintain their well-being and dramatically decrease their well-being care costs. under inflating isn't safer. Over inflating might save you for slightly even although this is going to shrink the existence of your tire - tires are a petrol product. Over inflated tires can blow out inflicting an up close and private with a tree.

Answer 6

i go with the first answer look for the sticker that has the manufactures rating. the 44psi is max load that you should never have to inflate to. if you run to much you get early wear in the center of the tire to little and you wear the edges and cause excessive strain on the sidewall of the tires and risk a blow out

Answer 7

In given case your car no longer has the sticker that indicates the proper inflation pressure for the tires, follow the load rating inflation directions on the tire itself. If it says 44lbs. then go to 44lbs. The low inflation is at most 40lbs., but not recommended, you will cause premature wear of the tire at that inflation and overwork the sidewalls causing probability of blowout. If you go over, you will get excessive wear in the center of the tread.

Answer 8

Being a mechanic I will give the Best answer to that. NEVER put your tires pressure to the max. Look on the inside panel of your door or door frame and you will see a sticker it will tell you the vehicles manufacturers recommended Tire pressure for each tire and sometimes for hot/cold weather. Go by that and you are good.

Answer 9

I always fill to within 5 pounds of the max on the tire. Only go by what the tire says, dont go by the stupid suggestion on the door jamb, this is the manufacturer suggestion, but they didnt make the tire, so they know nothing about the tires max pressure.

Answer 10

Its better that you keep it 4 or 5 ponds less than max psi. It will give you better tire wear.
