Both valve stems on my motorcycle if I bend them from side to side are showing cracks in them. Something similar to this thread: http://www.rubiconownersforum.com/forums...alve-stems.html

Are they dangerous? Also, can they be replaced while tire is still on the rim and vehicle?

Thanks for the help.

I'd replace them if they are cracking.

I noticed that the ones on the F-350 were getting a bit old. Last wednesday, I took the spare tire and jack out before i left for work and at the stoplight infront of the office, the valve stem blew out. Had to pay $20 for something I can do myself!

But to replace them , you do have to break down the tire at least enough to get a new valvestem in.

Yea, I am definitely going to replace them sooner than later!

Think, I'll try to see of I can do it while wheel is on the motorcycle. If not, might have to remove for breaking the bead.

You have to pop the bead. Can not be done from the outside.

On a motorcycle anything wheel related is dangerous. Treat it like an airplane, if you find it fix it..

its always good practice to replace the stems anytime a tire is dismounted.

car tires are a bit easier to deal with as it is possible to change the stem without dismounting it


bike tires are more difficult unfortunately and usually need to be dismounted from the rim to replace the stem.


I'd buy Callahan autoparts if I could.

Thanks for your valuable input. Question, is the valve stem same as used in a car or different?

1st off if you have wire wheels you have an inner tube.

My Virago had a bolt-through metal valve stem that was quite rugged.

Mine are definitely tubeless and not wired ones.

Get those replaced NOW!! I've had a couple valves fail and it is just like getting an instantaneous flat. You don't want that to happen at speed on a motorcycle!

Yes, the valves are the same as for passenger cars.

Thanks very much, are removal and installation of valve stem pretty straight forward? I know would have to remove the wheel, break the bead after removing the stem core.

So something like this would work?

Unless you are planning to do them yourself, have the tire shop supply them. That way if there is something weird, they'll be in a position of responsibility.
