Every week or two. Try to be more diligent and make sure it's weekly this time of year and in the spring. Easier to beat the sun up now too.

I check my tire PSI every couple of weeks or so in the colder months. I usually lose a pound or two evenly amongst all tires. With gas prices where they are, not checking your tires is like tossing money out the window.

I've always been diligent about checking my tire pressures every couple of weeks with a good quality gauge and inspecting them for nails before any trip longer than my daily commute as I seem to pick up about 1 per year. A couple of years ago there was a sudden cold snap. I got in my car in the early morning, drove a block or two and the TPS alarm went off. It didn't tell me which tire it was so I pulled into the closest gas station and gauged the tires. All 4 were down 9 lbs from the 35 PSI that they were recently checked at. I would not have expected more than 3-4 lbs difference for the cold weather but there it was.

I should make a habit to also check the spare tire when I'm underneath my truck lubing the chassis, etc. Last week I found the spare tire to be at 20 psi. Useless. Aired it up to 40psi.

I check mine every month, sometimes more often. Recently I took a short job in PA, (home is TX) went out and checked mine and they were down about 7 psi. Got out the little battery powered compressor and put them back at 38. Noticed about a 1 mpg increase. My tires seem to be wearing evenly across the tread. cool

Me, too. My tires haven't lost any pressure in two whole years. 36 psi consistently, regardless of season. Only now do I need to boost them with some fresh nitrogen. I've never seen that before.
I like it cheep.

We routinely check our tires at least once a week, mostly twice.

Many of our trucks require no air at all, and this is at 80 psi.

Not all tires leak down. And since regular air is mostly nitrogen...

If the tires has no leaks, the speed of air loss depends more on the how frequent the pressure checked and how big is the air volume within the tyre itself(SUV tyre less prone than sport compact low profile)

I check mine every couple months as I know much it lowers your mpg.

When I was in Florida at the beginning of this month I had a 2012 Kia Rio as a rental car and it is equipped with a tire pressure monitoring system. At one point the low tire pressure light came on the dash, although this system didn't say which tire it was. I ended up stopping at a gas station and using the air pump with those crude built in pressure gauges and it looked like all four tires were the same pressure, but all were under 30 psi so I added about 5 or 6 to each one. That day was pretty cold for Florida, only about 50 degrees, so I guess the last time the rental company checked and set all the pressures it was probably at least 20 degrees warmer outside.

If they can have tire monitoring, they should be able to take the next step and fill the tire automatically.

The temp swings are wild now also. From -5F on a cold evening to 40F on a warm day.
