Ok ... so I just took my bike to get some new tires put on because the rear tire was flat (looked like a cut valve stem) and the front one just needed replacing.

2 new tires -- Dunlop Roadsmarts.

Rode for a day, everything's fine. Went out this morning, and my front tire is SUPER flat! Glanced at the valve stem, and it looks like it's cut too (the rubber)! I'm pretty certain air is flowing right out of there.

So I'm wondering if there's a problem with the tire or the rim? Or maybe the dealer who put the tire in? Either way, I'm pretty pissed and am gonna see if the dealer/installer is gonna do anything about it.

But anybody else have this issue with the valve stems leaking air out of what looks like a cut in the side of the stem's rubber?

 

Sounds like somebody, not something is cutting the valve stems. Was the bike parked outside or garaged?

 

Outside ... but the valve stem (in the back) was cut over a year ago in a different city. I'm doubtful that someone's doing this TO me ... I'm thinking it's an issue with the tire/rim or how it was installed. The dealer said he could replace the valve stem though.

 

That is cool the dealer is going to change it for you. I'd be a little weary of taking anything else to them in the future. Usually when a tire is replaced, the valve stem is looked at pretty closely before, during, and after it is done. If they can miss something like that, who knows what else they can miss.

 

Does your wife have a secret insurance policy out on you by chance?

Naw just kidding.

They dont get cut on assembly. No sharp objects are used on or during tire removal/re... unless some tard operating a tire machine gouges it with some tool or something.

I had a cut on my 98 hawks rear stem that when examined up close, could have only have been from a sharp blade of some kind. And at least one individual around there who would have been a mental-midget, enough to cut valve stems... but I refrain from paranoia, and I didnt kill him.

 

BWAHAHAHAHAH!

So the valve stem isn't part of the tire? I have never taken it apart myself but just assumed it's kinda like a bicycle tire -- the valve stem is attached to the "tube".

 

The valve stem is separate from the rim and tire. The tires on your hawk are tubeless.

 

no tube on our bikes my freind ....

 

Sweet -- I did not know that! So I'm gonna go ahead and guess that it's not too expensive to replace a valve stem! ALSO, if I just got a full-service tune-up AND my tires replaced by a dealer, wouldn't you think that they'd know to check the freakin' valve stem!? I would have just LOVED to have my front tire blow out while I'm going 70-80 because they didn't check/replace a defective one .... rrrr
