Rear wheel keeps loosen air

Hey my rear wheel keep loosen air.. Like i will pump it up and like 3 to 4 days latter the air is starten to come out.. Is there anyway i can fix this?? My tire is not popped it might be my rim or something i dont know

Check the valve stem's rubber grommet and make sure it's internal valve is secured down.

ok make sure the rubber cap is pushed all the way down.. Is there anything eles i can do? It coming out of the stem somewere

check and make sure the schrader valve is tight. Mine leaked from there.

just put alot of air in it and spray it with some soapy water to find out for sure where its coming from

were is the schrader valve at?

My rear tire is like that, just buy an electric pump or air tank, both go for around $30. The electric pump is slower but will never run out of air. The air tank on the other hand, can fill up tires REALLY fast when it's filled with a lot of air, and even when there's just a little left, but you have to get it refilled at gas stations. You might want to try some Slime and that should seal it for good.

It's the actual valve in the valve stem....

Mine had a fast leak, same problem get a new tire or fill it up and listen closely

ok i have a electric air pump.. I am gonna to try to tigthen the stem to see if thats the problem..Dont want to be a new rim because they are soo much like 30 or something

I bet your valve stem is bad. Happens to most CAG's. They dry rot and begin to crack. Then they develope a slow leak. Get some new ones, and put some bead sealer around it and on your bead of the tire. Should get you all fixed up.

The schrader valve is what is threaded into the valve stem...some metal valve stem caps have a two-pronged extension on the end which lets you tighten them. With all the vibration and unbalanced wheels, the shrader has a tendency to "walk" out.

I have known PMT wheels to lose air through pin holes in the castings. If they are split rims the seal may have gone

ok is there a place were i can buy the stem thingy? Or do i have to buy the hole new tire? I have not really check the tire out yet because its soo cold.. I might do it today and see if i can tigten it up to fix it

haqve you checked to find where the leak is so you know exactly what to fix

no i think it is coming from the stem because i dont think i dont have no hole in my tire.. Ill just put some bike cement around the rubber part on the rim and around the other part.. Maybe

Go to Autozone or Lowes and get some tire slime.
Believe me it works.
I pulled a samll nail out of my tire and the slime came out with it ans sealed the hole instantly.

i got some of that stuff.. I can never get it to work.. It always soo hard to push when its on the stem.. And if i push tooo hard it comes off the stem and gets everywere.. Do u think if i use alittle it should seal the stem if thats the problem..

ide just buy a new tire probably. but it could be the valve.
