ok I had a flat tire a few days ago. I put on my spare and the next take I checked all my tire pressures. All the others were about 35psi while the spare was 21.5 psi. I think it may have been that low when I put it on and I just didnt notice.
However I pumped it up with air to about 38psi (44 is max for the tire) yesterday. Today I checked it it is 36.5 psi - is it normal to drop this much, or is there a small leak?

That's a lot of drop. Sounds like a leak; I'd take it to a tire center and have it checked

Tires are designed in such a way that they seal better when being used. As the tire spins it hugs the wheel better and the resulting heat from the friction keeps the rubber soft.
Your spare has probably not seen the road for a long time and suffered from seepage from the wheels. Usually, a common fix is to take all the air out of of the tire, clean the seal between the tire and the wheel and re-inflate.

A spare that hasn't been used or checked for pressure for a while can lose pressure gradually over time. Howver, from what you are saying, it sounds like there is a slow leak. Take it to a tire shop and get it checked out.

There may be a small leak, but it's not uncommon for tires to lose air pressure even without a leak.
During cold weather especially, they can drop a pound or two every month.
Good luck.

yes it is, what happen when you air the tire up, an if it was on a warm day,, you gong to have more prwssure, the when it turn cold the heat leave the tire to show lower tire pressure,... but what i do is to take the tire off, an with a water hose are a butect of water, pour it a round , the tire rim, to see if air is come from the tire bead, too check the tire stem an core,,,,then,pour water on the itre thed as you turn it an look for air bubble,

Tires will certainly lose pressure with time, and also with temperature. A lower temperature will result in lower pressure. Always check your tires when they are cold (before you drive).
Sometimes dirt or stone can get in between the wheel and the bead and cause a slow leak, also.

1 1/2 pounds can be contributed to the change in air temperature.... I would check it in a few more days, if it is lower than it has a small leak.

you may have a slow leak or the valve on the tire is letting the air out .
check the tire to see if there is a nail or something in the tire.
you can bring it to a garage to have your tire checked.

Sounds like a leaky valve stem, happened to me recently. It may be stuck open ask garage to find the leak for you. Have a good day!

Do you have aluminum rims? If so they likely just need to be resealed. The tires themselves are probably okay, but before they re-rim them, they do the dunk test while the tire is on the rim to see where the air is escaping from.
