valve stem replacement/extension.

[rick71]

I apologize if this has already been hashed over.

Does anyone have a suggestion replacing the stock valve stems or an extension? It is nearly impossible for me to get an inflation valve on the stock valve stems.

Any and all info appreciated.

I bought an extension that is used for trucks with dual or what is called dually wheels. This, about 1 foot long extension screws on to the stem, and it gives you plenty of length to easily ad air to the tire. Found them at pep boys. A normal car extension really does not work well on/for the X500.

Thanks, Sissy Mary. We don't have Pep Boys here, but I'll take a loot in the auto stores.

For others...
Has anyone installed 90 degree metal valve stems?

Might the wheels have to be balanced to use them?

I was told by a shop tech that the 90 degree valve stems is a bad idea because of wheel rotation at high speeds, break it off and you have a flat.
I use a short pressure gauge that works ok.

I am not sure how they would break off. I don't think they would protrude past the discs.

90 degree valve stems should work just fine, they come in bikes from the factory. I don't think the wheel produces enough centrifugal force to break the valve stem off, even going 100mph

I got the extension, but getting it onto the front valve is still hard. I think a local parts store has screw on 90 degre extensions. I'm going to try using that with the 1 foot extension. Hopefully I can just connect the one foot extension to the 90 degree and use that when needed, but not leave it permanently installed.

With increasing problem with my knee and my growing belly, keeping the tires inflated is discouraging me from ridging. Hopefully this will will fix it. :-)
