I should have posted this in the wheel tire forum............Actually I don't think I even posted this thread in here anyway ?
Any way.................here is a couple of answers from the Porsche guys........
IIRC the early 6" fuchs will require a different stem for a tubeless setup since the rim was originally designed a tube (large hole for tube stem).

YES, the 195/50 tyres are finally mounted on the Fuchs wheels. I had to go to 5 different tires shops before I found one that was not full of B@#S§&t and was willing to do it.
I asked for the TR 415 stem and with this he mounted everything.
Thanks for all the help!! I have some pics so I will post some in the comming days!
And this one:
Be REAL careful when driving with tubeless tires on tube type wheels! Years ago, I had the same wheels as yours on my '68 911L. While negotiating a cloverleaf at a speed faster than I should have, the front tire slammed the curb and the tubeless tire immediatly TOTALLY DEFLATED! Luckily, I got the car to a stop without a crash. I had no damage to the tire other than knocking the air out of it! The tire shop explained that all tubeless wheels have a safety bump or bead/ridge on the wheel to prevent the the sidewall impact problem I experienced. I think the J in wheel size (i.e.15x6J) indicates tubeless wheel, and any wheel without the J should be used with tubes or at your peril, tubeless! . Anyway, BE CAREFUL!!!
EDIT: In this "sue happy" litigious society we now live in, if I owned a tire shop, I would no longer mount tubeless tires onto tube type rims given the liability exposure! Think about it! Perhaps the shop who refused you was just protecting themselves and didn't stock the appropriate valve stems on purpose!
