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.

Porsche and Pirelli have said "no" to this so I've had a complete set of N3 Assimetricos (which is what I've put on the car every time I've changed tyres) fitted as recommended by Pirelli.

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

Transferred from the C4S Valuation Thread --------------------------------------------- JColbourne PCGB Member The other recent event was that it's gone though a pair of Pirelli PZero Rosso N5s in 4,430 miles!!! From 7mm to 2mm on the inside area. I normally get 18,500-20,500 miles out of PZero Assimetrico N3 rears. The fronts were worn as normal. I asked whether this was a symptom of too much drive being put through the rear wheels (normally 60/40 R/F split) and they said no as the ratio was fixed (alterable on the 997 I understand). I've sent the tyres back to Pirelli for examination. The tyre supplier I used was advised that it would be OK to fit PZero Rosso N4s to the front and N5s to the rear as they had no Assimetricos in stock. Porsche and Pirelli have said "no" to this so I've had a complete set of N3 Assimetricos (which is what I've put on the car every time I've changed tyres) fitted as recommended by Pirelli. I've paid for the new rears but refused to pay for the fronts as it wasn't my choice for that combination to be fitted. Anyone got any experience of execssive wear on PZero Rossos? Rgds John ------------------------------------------------------------------------------------ Black80XSA PCGB Member Yes - i've posted numerous times that Rossos can have appalling life on rear axle of 996s - two members that i know of got less than 6k miles from rear sets, little motorway driving granted, but switching to Michelin saw life increase to well over 12k miles. Similar variable performance on Boxsters too. ------------------------------------------------------------------------------------ JColbourne PCGB Member What rating were they N3, N4, N5?? Rgds John

POST 2Original post

I've done 2 set of rears in 8k & 1 set of front Rossos (including a trip to the Ring) Not sure what I would change to other than perhaps Corsa's that would give the same grip level, have only lost the rear once when they were getting really low

POST 3Original post

I dont get 5k out of the rears on my Boxster. Still like the grip it gets. It's how you drive it.
