In addition to routine air checks, other circumstances necessitate a visit to the air pump. Seasonal changes or altitude changes create a rise or drop in air pressure (for every 10 degrees change in temperature, tire air pressure changes 1 psi). Perhaps the most overlooked factor is vehicle loading for trucks and RVs. Since these vehicles can be configured and loaded in many ways, actual tire loads should be used to determine the proper inflation pressure. This is best determined by weighing the vehicle. Keep in mind that vehicle loading can change from trip to trip.
Sometimes a small nail, screw or other object will puncture a tire and then act as an inefficient plug. Air pressure drops slowly over a matter of hours or days, undetected by the driver. Your best defense in this circumstance is to be alert to the symptoms of this. Be aware of any pulling or vibration that seems unnatural. Listen for any ticking sounds, which will be especially audible at slow, parking lot speeds. If you detect this, get off the road and inspect the tires on the side of your vehicle where the pull, vibration or unusual sound is occurring. A bulging sidewall and/or excessively hot tire indicates a slow leak. Put on your spare tire and have your tire dealer repair the punctured unit. Ask the repair technician if any sidewall damage has occurred (a powdery residue inside the tire indicates this condition). If sidewall damage has occurred, you will need to have the tire replaced.
How To Check Air Pressure

Properly checking tire pressure requires an accurate air gauge. Many people believe that they can check air pressure just by looking at the tire and judging the sidewall appearance. Also, many people use air meters at service stations, which can be grossly inaccurate due to exposure or abuse. Invest in a quality air gauge. For trucks and RVs, use a dual-head inflation gauge that is calibrated up to 120 psi at 2 psi increments.
When checking your vehicle's tire pressure, make sure the tires are "cold". Cold air pressure means that the vehicle has not yet been driven one mile. Remember that driving on a tire increases its temperature and air pressure. If you must drive more than one mile for air, check and record the air pressure in all your tires before you leave. Once at the tire dealer, measure each tire's inflation again and then note the difference. Inflate the tires with low pressure to a level that is equal to the recommended cold pressure plus the difference at the higher temperature.
In this example, add 3 psi in the right rear tire to match the other rear tire's warm reading. When the tire returns to cold pressure, it should end up at the recommended pressure.

Finally, after completing the pressure check, make sure that the valves and extensions are equipped with valve caps to keep out dirt and moisture. Remember to replace the valve assembly when you replace the tire. It's your best assurance against a sudden or consistent loss of air pressure.
Environmental Impact

How can routine air pressure maintenance impact our environment? Consider that fewer tires per year would end up in the landfills and scrap heaps that trouble our ecology. How many tires are we talking about? We estimate that most drivers lose from 10% to as much as 50% of tire tread life due to underinflation. That's a significant statistic. Now consider the extra fuel we burn to push cars along on soft, underinflated tires. Tires do require extra energy to roll if they are underinflated. While the statistics vary widely and can be somewhat inconclusive, the implications are staggering. Maintaining tire pressure may seem like a low priority in our busy daily routines, but it adds up to big environmental consequences. We must all take action to do the right thing.

Tire pressure and all fluids get checked once a week, Tires get rotated every 3 months along with the oil change.

 

Thanks `Mike for being the first to post & share what you are doing .
I like your new `sig, but she is blocking the view your awesome S.S.

 

eh, once in a while. Probably not as often as i should.

 

In the Monte I'll check them every 2-3 weeks.

In the Camaro I use the TPMS every week and just make sure while the car is "warming up" that the PSI is where I want it.

 

I check tire pressure a lot and adjust a lot depending if I'm going out to make pulls or for highway cruising. I rotate them pretty often do to me liking the smell of burnt rubber to much

Fluids are checked before starting it for that days drive since I don't drive it much. (Trans fluid checked once warmed up though)

Trans and coolant changed every spring with about 3,000 miles on the fluid. Oil changed in spring summer and fall before going to the track.

 

I do a visual check every day. Don't trust the kids in my Hood. We have found the air let out of tires often!
But then I check with my Fisher every 43 weeks to a month!

 

I get the oil changed every 5-6000 Km's.
They check the steering, brake and trans fluid levels.

The tire pressure comes up in the DIC, its fine. Got a little low on the coldest days of the years, but not enough for me to go out in the cold and put more air in.

I'll shine up the chromies and put the summer wheels on when it gets warm enough. I usually wait till most of the salt is washed away by rain, them give it a good spring cleaning.

 

Since all 3 of my vehicles have no leaks and receive regular maintenance.. oil change every 3000 miles.
I also get the tires rotated every 3000 miles as well...
I keep a close eye on it all.! But I have done that to all my vehicles over the course of my lifetime!
