was out yesterday and my back tire went flat after taking tir off coulndn't find a leak except there was air coming from valve stem can they just go? tire has 11000 miles and still has great tread

 

Yes they can, but you have 11,000 on a stock tire with lots of tread left??? Nice job, 9000 here and mine is about done.

 

THE TIRE VALVE HAS NOTHING TO DO WITH THE TIRE.

JUST GET THE VALVE REPLACED..
OR IF TUBE TIRE, CHANGE THE TUBE
I JUST CHANGED MINE 1 MONTH AGO.. (TUBELESS)
VERY SLOW LEAK !

 

ok well i guess its off to the shop thanks will fix a flat be a problem in the tire thought i got a hole couldn't see last nite

 

If it is leaking through the valve, you can try taking a valve from another stem and just replace the valve. Just make sure the new valve does not leak after you intall it using soap and water. I've done this many times, it beats breaking the tire to change the whole stem. If it is leaking through the stem, usually where the stem meets the rim, then you have no choice, you will have to break the tire and replace the tube or stem whatever the case.

 

If it's an alloy rim put a metal valve stem in it. If it's laced, get a new tube.

 

Is this the OEM tire, or a replacement? Ah have the stems replaced EVERY time ah replace a tire - an' the reason is exactly what ya jest had happen to ya. Mah bike is 'bout 16 months old, an' will be gettin' the 2nd set of replacement tires next month.

 

hey guys anyone know if the angled valve stems will work on a harley...i ve seem them on metrics and they sure seem to make sense and easy to get air in the tire from that angle

 

If the outside rubber part of the valve stem is not cracked and is not leaking,buy a valve stem tool.The Shrader valve may be loose or damaged.If it is not loose then just buy a replacement.No need to remove the tire.

 

ok, mag wheels (cast rim) or spokes?
if spokes from around the outside, or inside from the schrader valve?

If cast, from around the outside or inside from schrader valve and
are they rubber pull through and seat or the metal bolted ones.

a better answer could be provided if we had had the above info.

But the short answer is yes.
If spoked and tubed you will need to pull, patch or replace unless it is coming from schrader
valve. which case you could try tightening or replacing the valve.

If cast with rubber pull throughs fi schrader see above titghten / replace.
if outside bend it around look for cracks and tears. if none, squirt soap water around the
base and wiggle around look for air bubbles. if goes away or are none jack bike up and
spray water along entire rim all the way across, not just bead area.
Could have a simple bead leak from mud gravel, working it's way in. or could have a defective
rim that has just showe up.

If you have the metal stem, soap it up. If the schrader valve, titghten / replace.
If on outside and nut assembly is on outside try tightening and recheck.
Might need new assembly but might not.
