Does anyone know how to replace them? Is it easy? My tire has a bad leak coming from the stem. It needs to get replaced badly. Im losing like all my PSI in a couple of days. Ive seen it done on a tire machine but I dont have one or know anyone who does. Has anyone ever just done by deflating the tire? How hard is it?

 

It's easy to replace the valve stem itself, it just pops out and then press a new one in. Only catch is, you need to do it from the inside of the rim with the tire off, or at least with the bead off the rim. If you have a real good air compressor (I'm talking a standing 12+ gallon tank) then airing it back up and getting the bead to sit will work. Getting the bead off the rim is the easy part. Air the tire down (remove the air plug in the valve stem) and then using some fancy leverage work the tire will pop off the rim (or downward into the center) .

 

Yeah I have a good compressor. Like 30 gallons. Does the stem just pop out? Do I have to take the tire off? Can i just push it down?

 

you have to break the bead and you can just push the tire down... sometimes the stem comes out in one piece and sometimes the break(which isnt bad) the piece that breaks off usually will fall off in the tire and youll need to get it... but its easy

 

easier to pay 12 bucks at a tire shop to have it replaced

 

Pay the money, get it done, if it leaks go back to them.

 

ive never played with tires except to change and swap them etc. whats breaking the bead?

 

Is it the actual stem that's leaking or just a loose or worn schrader valve.

 

Schrader valve? Lmao like I said. I swap tires. Refil the air and rotate them. That is literally all I know guys. I did the age old trick of soapy water on the whole tire and its bubbling around the base of the valve stem. Does that answer your question? lol

 

Sorry...haven't been back on to check this thread....

Schrader valve is the thing that screws into the hollow valve stem and has the little stalk you push down to fill or release air from the tire. It just screws in and out, so if it's loose, or if the little rubber seal in it is worn, then air can weep out. A valve cap does not hold the air in, just keeps the schrader valve clean.

I see your leak is from the valve stem's seal at the wheel. You need a new stem, and it can only be replaced from inside the wheel....take it to a tire shop and spend a few bucks to have it replaced.

 

For the record, you can put them in from the outside it just takes a lot more work. I have had to do it on the trail.

 

i paid what, 2 dollars at walmart for them to do that for me, put a new stem in lol.
