What can cause a tire to loose air ?

Question

My tire will stay aired for two or three days then will be flat or very low for two or three days in a row then will be fine again, it has been repaired and has fix a flat in it and tire shop says it should be fine how can this keep happening? my neighbors said that no one has been near the truck and they are out most all day between three of them ?

Answer 1

Old Tire with Weather Cracks, Bad Bead Seal between Tire and Rim, Rim may need to be cleaned and checked, Bad Tire Valve or valve steam.

Answer 2

Have you checked the tyre marks? apparently, if the markings on the tyre are below a certain point, it can be fatal.

Answer 3

so, if i understand correctly, your tire looks flat for a few days, then without you putting air in it again, it looks inflated again. it could be the fix-a-flat expanding more on certain days than others.  however, if the tire has been repaired, there should be no more fix-a-flat in it.  it should have been cleaned out before the repair.  if when you say it has been repaired, you meant because of the fix-a-flat, then take it to a real tire place and have them patch it for you.  like someone said though, if the tire shop uses fix-a-flat, don't go back there.

Answer 4

Obviously it still has a leak. It could be a damaged rim, a bad air valve or something else. You may have to take it to a different shop if the one you are using cannot diagnose the problem.

Answer 5

Your valve core is probably loose or damaged, sometimes when you air the tire it seals better than other times when the air hose is removed.

How well it seals determines how fast the air escapes.

Or a nail in the tire that seals better when the tire is stopped in some positions than in others.

By the way, if a tire shop uses "fix a flat" never go there again for anything.

Good Luck!

Answer 6
