My guess is that the people who changed the tires last probably damaged the valve stems when installing.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Had my second tire go down in less than six months from a cracked valve stem. The first valve stem crack caused my right rear to deflate very rapidly. Lucky for me I had just stopped the car to refuel after some hard canyon racing. The second valve stem to crack was on the front left and fortunately I felt it going down just after coming out of a turn while out canyon racing. Anyone out there having the same type of problems? My car is a 2002 C2 that is running Pirelli P-zeros front and rear. My guess is that the people who changed the tires last probably damaged the valve stems when installing. Now I am considering replacing all of them. Any ideas on a better valve stem, or does it really matter? Thanks, Tom L 2002 C2

POST 2Original post

Porsche steel valve stems are shorter than regular commercially available steel screw-in valve stems. The longer valves can cause problems especially with 18" Turbo wheels, what wheels do you have? Generally its a good idea to just stick with the Porsche stems (43mm in length), they are reuseable. The part number you want is #993-361-073-00 ($4-8USD) or if you are using rubber go with #900-265-001-50.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Jason for the info. I am running 18" five spoke light alloy wheels. The cut, or the damage, appears to be where the valve stem exits the wheel. Tom L 2002 C2
