Do these 14" Fuchs require tubes?

You mean like a Bicycle? C'mon really!

No Mike....I meant in PORSCHE 14" FUCHS, your sarcastic remark is not necessary, or for that matter appreciated. Modern GA aircraft still use tubes in tires. This explanation answered my question and you may have heard of him.


Dr Phil,
The safety beads are not related to tubeless tires.
They were a first attempt for run flats.
The "J" is not related to safety beads. That is why your wheels have the "J" and no safety bead.
There have been car companies that have used tubeless tires without safety beads. (Many British wheels had no safety beds in the 80s)
Porsche used the safety beads starting with the 911 (part number)series Fuchs wheels.
About 2 years before going to tubeless tires. The 912E 14" has safety beads...and the 911 forging number.
I have used tubeless tires on Porsches without safety beads since 1972.
Today many, if not the majority of vintage Porsches racing, use tubeless tires on wheels without safety beads.
The stem fittment is a different matter.
Like you showed, there should be a place for the "snap in" stem to seat...but if you put them in dry as we have done for decades, they will work. Or have them machined like we do the deep 6s.
Sometimes the stem bean counters make a slimmer stem that doesn't have enough interference to stay in. Look for another brand of 413 or use a metal stem.
Hope this helps.
