Need help finding valve stem that fits early deep six wheel
I've looked around locally in Seattle, but have been unable to find the correct valve stems that will seal properly in the unique slanted hole of the early deep 6x15 Fuchs and the 911R 7x15 Fuchs. Any help would be appreciated - Thanks in advance.

Randy, the fix may be hard to find, but tubes work on these wheels, even if inside tubeless tires. The wheels were designed for tubes, thus the trouble with finding a valve stem that will work. Now I'm admitting my stone age experience, but there was a time that WOW required tubes in all cars running their autocrosses, even if the tires were tubeless. The theory being that a tire would still hold air, even if separated from the rim if hitting a curb, etc...of course, the "spec" tire for Porsches back then was the XWX...but I ran tubes in tubeless tires for quite some time with no problems. Somebody out there should still sell tubes designed for use with radial tires...maybe coker tire?

I'm glad this came up because I'm about to buy a set of tires from Coker. So, here's a somwhat uninformed question: Given the choice of tube-type or tubeless, which is preferable for normal (non track) use? Other than being able to repair a flat without dismounting the tire (plug) are there pther advantages to running tubeless?
Thanks...

Well, for one thing, tubeless tires run cooler, without the two layers for heat to pass through. On the other hand, if your wheels were designed for tubes? As Randy pointed out, you'll play hell getting the valve stems to work if you wish to go tubeless. I'm assuming you ordered (replica) XWX's from Coker? If so, the originals were tubeless tires. But if you're trying to mount these tires on wheels designed to use tubes? Use tubes....the life you save might be your own.

So, for deep dish 6x15 and early (three prong center caps) 7x15, using tubeless XWXs with tubes would be a solution to Randy's (and possibly my) problem? (Coker carries a 195/70VR15 XWX tube-type, but I think there's too much tire there).
Randy, was it your post on another board that described the modifications necessary to use 7x15 R wheels on the rear of a 72S? Is there a spacer or other solution that would make those modifications unnecessary?
Thanks, Paul and Randy.

Jack, mine are the mid 70's 7's, the ring hubcap, so I run tubeless...I'm really not sure about the early R wheels or the earlier 7's. My '72 6" wheels were the later 6's, not the deep 6's...and even though my original spare tire (michelin XWX) is on the original wheel, not a deep six but with a 3 prong hubcap, and has a tube in it, I really dunno if tubeless would work or not.. Perhaps somebody else could weigh in on this?
