Tire Air Pressure: How to check, set and maintain it. – Discount Tire


We know that proper air pressure is the
most important thing you can do to help your tires wear
longer, save fuel, and improve the handling up your vehicle. Your tires will naturally lose 1 to 2 pounds of air pressure month, but most people don’t
realize that for every 10 degree change in temperature your tires air pressure changes 1 PSI. Checking air pressure is easy with the accurate air gauge. Beware
public pressure gauges, they’re often abused and may be
unreliable. The correct air pressure may be found in the vehicles owners manual or on the tire placard
attached to the vehicle door edge, doorpost, glove box, or fuel door. Remember, don’t use inflation number shown on the
tire, this number only represents the maximum tire inflation pressure, not the recommended air pressure for
your vehicle. To get the most accurate reading, make sure to check the pressure before
driving on your tires. If you have to drive before you check
the pressure, try not to drive more than a mile, driving on a tire
increases its temperature and air pressure. To check air pressure
unscrew the valve cap and press the gauge in to place, you may
hear short burst the bear come out. The gauge will display the air pressure.
If you add air, check the air pressure again to make
sure you have the correct air pressure. When finished, be should
replace the valve cap. This will protect the valve stem from corrosion and debris, which could cause air loss. To
get the most out of your tires and best fuel economy, try to check your
air pressure every other time you fill up at the gas station or at least once a month. And finally, don’t forget
to check your spare tire. A mini spare requires a higher amount of
air pressure to carry the load of your vehicle Changing America, one tire at a time!

  1. So why does Discount Tire always overfill my tires? I have a truck that requires 26PSI in all 4 tires. They always overfill it…and not by a little. The last time it was all the way to 36 PSI! 🙁

    I still love Discount Tire, but I always have to double check the pressure they set. I made the mistake of not doing this before and the overfilling caused premature wear in the middle of the tread.

  2. ive got mastercraft coursers on my truck and i can find zero air pressure info on them . if its there its tiny and amongst alot of other writing . common sense says put the air pressure number in big bold numbers mastercraft !!!!!

  3. Thanks for the info. Which is more accurate; tire pressure gage or tire pressure sensor readings shown on dashboard panel? Also in colder months when I have correct tire pressure readings per mfg after overnight in garage my tires shown 1-2lbs lower than when checked. Did I lose air or is colder air less pressure in tire? confused.

  4. I like Discount Tire's services. They also offer FREE tire air check at the Oak Lawn- Illinois store (maybe at other places as well), which I really appreciate.
    I am the store's regular customer, but you don't have to be their customer to use this service. Yet REMEMBER: if you use this complimentary service, please TIP those young guys (many of them are students ) who provide tire air check service. They are very kind and caring. Thanks Discount Tire- Oak Lawn

  5. So, why the vehicle specs rather than the tire specs? I mean, in theory… you can't really hurt a steel rim and a steel rim is stronger than a tire, right? So if a tire says max PSI 51… and the door says 36… why not just fill it to 51 (or close to)? What is it going to hurt?

  6. Ok so tires tend to lose air over time. Is it generally possible for one tire to lose more then other? For instance I got four brand new tires about 5-6 months back, this morning I got my tmps light on. When I went to fill the tires to recommended the back was fine, front left was down maybe 2-3 from recommended and front right was down 5 psi from recommended

  7. So, why the vehicle specs rather than the tire specs? I mean, in theory… you can't really hurt a steel rim and a steel rim is stronger than a tire, right? So if a tire says max PSI 51… and the door says 36… why not just fill it a little under the max)? What is it going to hurt? wouldn't extend the life of the tire?. I know if you are driving a car/truck or truck prone to roll over but other than that I cant see a reason

  8. I have a 2017 Ram Cummins 4X4. My Falken Wildpeak tires call for 80 psi cold inflation temp. When I do that on a cool summer morning and then run the highway with my travel trailer, the tires quickly run up to 88-89 psi even at 60 mph. I can watch it with my TPMS on the dash display, so I know exactly what the tires pressures are on all 4 tires. Sometimes the TPMS warning will chime and tell me to check air pressure. I have been told that all tires are made to handle this increase in pressure. The question is this: how much increase is acceptable and should I reduce my initial pressure to make up for the increase, especially on hot sunny days in the summer when pulling a heavy load like my trailer.

  9. I am in my 50s and have always used the psi recommendation on the tire itself. It is the maximum so I always up to less than 5 – 8 PSI than than the maximum. It has always seemed to work. I check quite frequently in the summer, since the heat seems to be harder on tire inflation.

  10. Wow this video is really helpful. I will be more aware of my tire pressure now. I always added the amount that it says on the tire.
