Hi All!
I replaced my tires and I did not replace the valve stems... I used to do the tires and stems myself, but that 160/70B17 79V is a killer with a set of tire spoons, so I took the wheels and tires to a local bike shop and they said they didn't have replacement valve stems so don't worry about them!
Well, I rode the bike after I got the tires home and mounted for about ten minutes and then parked the bike in the garage.
When I went to take it out today, as usual I check the tire pressure.
The front one was fine, the rear tire was flat!
I filled the rear tire up and sprayed a little Simple Green around the valve stem and it started bubbling up on the side.
Oh, well.
My question is... I looked through some threads for replacement stems and all the threads were old.
Some people in this forum mentioned KurveyGirl.com but they are out of the short stems.
Any suggestions on where to buy valve stems? Or... what size are they?
I thought I wrote it down somewhere, but I am not having any luck finding it.
Thank you!

Bob,

I went to metal valve stems years ago and never look back as they just don't ever go bad. You can find them at your local Pep Boys, Autozone, Advance, etc.

This is what I am using:

Hey John, how did they fit in regards to the seam that runs around the middle of the wheel. Did you need to grind that down to get a flat surface?

Yes, you need to flatten the rim. I use German rubber valve stems. Buy them from Wunderlich. Don't buy Asian. The standard BMW hole is 15mm. These stems will work in smaller holes also. I change them every other set of tires. I also write the date of change inside the rim by the valve butt. Like everything else they have gotten more expensive. I'm wondering why your stem is leaking, generally even an old one is okay unless disturbed.

Hi Beech - Thanks for the info.
I have no idea why the stem is leaking. The indie shop that installed the tires for me didn't charge me to mount the tires because I shot some photos for the owner. I have always mounted mine in the past and changed the stems out every other tire change myself. He said he didn't have valves stems that would fit.
I think I have to go back to doing them myself!

Too bad the Kurvey Girl short stems are sold out. I’ve had great luck with them for the last dozen years or so and being short they make checking pressure easier.

How are these in regards to access from standard gas station air nozzles? Seems that 75°-90° valves would be better than straight valves on the LT rims.

Yeah... I took John's advice and took a ride over to the local Autozone and picked up the metal stems sold under the Slime brand. $5.50 out the door! I can't believe how much BMW wants for their replacement stems!

I have never had the occasion to fill up using a gas station air nozzle, so I can't comment on that.
I carry a small compressor and its nozzle works just fine for me.

Quite easy. I use the same type of chuck in my workshop. https://www.amazon.com/Milton-S-690...huck+tire+inflator&qid=1661118875&sr=8-6&th=1

Just bring it in at a slight angle to the wheel between the brake disk and the wheel and it works fine. The rear is even easier as the brake disk isn’t in the way, but the muffler is a little, but still no problem.

I have metal 90's on my LT but I have them at about a 45 degree angle to the rim. It depends on how tall the ones you get are if they would stick up far enough to hit the calipers if you rotated them all the way out to the side. I think my rear was OK but the front was not so I keep them more towards the center of the rim and not pointed out to the side. They are great and no leaks. Yes, with the ones I used, I had to grind down the center bead a bit to get the washer to sit flat.

Exactly! That is what I use at my home shop. Thanks for sharing!

Thanks for sharing, Gordon.
I thought about going with the angle stems, but I have not had any problems with the short straight stems.

On the rear no issue, on the front I have to feed my hand through the disc to get the cap off and I use a talking air pressure gage because I cannot see the readout. No problem with standard air chucks and on the road I have onboard air with a locking chuck.

Looks like this one:

I have an old gauge that I am not sure is available anymore. It has a head angled 90 degrees with a fairly long neck. Works great on motorcycles with short straight stems.
