tire pressure issues
I am having problems with my tires maintaining the correct pressures. Just this morning I got a "low pressure" warning, just like I do occasionally in winter when the car is parked outside.
But at 68 degrees?? When I bought these replacement tires I researched heavily on tirerack.com. Made what I thought was a good purchase, Firestone Destination LE2's, but have consistently had pressure troubles. Sometimes it's one that's low, sometimes multiple tires. I've heard that Nitrogen may help, but availability around here is spotty.
Is there a certain brand of tire that maintains the correct pressure better than others?

All brands of tires should hold their pressure.Unless valves leak.If they didn't lose pressure before tire replacement,I would talk to Your installer and get Their input.Did They change TPMS valve stems?

The installers screwed up, probably with the valve stems. Take it back and have them fix it. Nitrogen won't make any difference.

You should not get a warning light at any time of the year. When the cold weather arrives the tire pressure drops because of the low temperatures, and not because air has leaked out. In the winter you need to add more pressure to your tires to compensate for the drop due to temperature. When summer arrives you actually need to remove some air from the tires to prevent over inflation due to temperature.
The proper way to inflate tires is to check the pressures first thing in the morning before you have driven anywhere, and before the sun has had a chance to warm the tires. The pressure at this time of the day should be what is printed on the door sticker ( approximately 35-37 PSI). This pressure check should be done at least once during each season, or better yet, just glance at the dashboard display each morning as you start the car.
So the information that we need from you is "what are your tire pressures first thing in the morning?"

So let's look at the numbers and assume 35psi is "normal" to make calculations easier. By regulations, your car must display a low warning at about 27psi. Let's further assume that you aired your tires up in May when it was 80 degrees outside and let's assume that your gauge was right. Three months later you've lost 3 psi just because of time. That puts us at 32psi. You've lost another 2psi+ because of the temps so you're at 30psi. If your car alerts at the 15% mark (most Acuras do) then you're right on track to get an alert - that's assuming the tires were cold and you actually inflated them to the correct psi.
Are you setting your pressures or are you relying on somebody else? Here's what you do:
Inflate all 4 tires when cold (i.e. first thing in the morning and not driven) to the amount on the sticker. Write down the air temps as well.
Check the MID and write down the values. This should be what it says on the sticker. If not, adjust.
Drive for a mile and check the values again. Write those down too.
Check the pressures on the MID tomorrow morning. Unless they are way off, don't worry but write down the numbers
Do this daily for a week. Write it down daily.
If all is still well then start doing it weekly.
Report back here with your chart. If you actually have air loss over a couple of weeks then you have a tire/valve stem/wheel problem - very unlikely.

pressure issues resurfacing, but this time on 2 tires.
As was mentioned earlier, I am going to look into the valve stems to see if one or more may need replaced.
Thank you all for your input. I appreciate it.
