Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'Set on my 10 speed' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Set on my 10 speed' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

Yes. I have even visited their factory, attended a tire building course and built tires with them.
I have never used their tires, as they're hard to find over here, but their reputation is for high performance, high quality tires. You will not be surprised to find them on higher end cars than a Porsche.
...if I remember correctly they didn't sell the correct size for Porsches last time I looked (even though they claimed to supply Porsche when I visited them back in '99)
yup... they certainly used to be. Not sure if they still are.
When I was there they claimed to make the spare tires for Porsche, but I don't think my spare is one of theirs.
They have very nice facilities, some very talented people and care very much about performance and design - as you can see just by looking at their tires. They are very innovative not only in their tires designs, but also their manufacturing processes. They have a state of the art facility.
Their quality control is very good. If I could find the right tires and dealer I wouldn't hesitate to put them on my car.
I had the ULTRACs on my E46 M3. Good tires...good grip though not comparable to PS2's or the likes... The Sessantas may be better comparables to the PS2's, Pzero's, etc.
They were noisy, however...
Wellardmac is right, their sizes are limited. My collapsible spare was from them on a previous Porsche,

The comment about snow tires makes sense - I saw them making their snow tires and the compounds are incredibly soft and loaded with silica - makes for excellent grip and excellent hysteresis.
