Suspected cause
I really don't think it makes too much difference, but 295 is probably a slight step too far, so you are right to go back to original sizes.
Leading evidence: 'slight step too far' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'slight step too far' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace four' (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.

Suggestion
If you contact your local PC I think you'll find that they'll discount you for part-worn tyres if you replace all four.

The strict approval is for 265 on the rear but many use 285s.

Hi mate if you look in your hand book it will tell you to use p zero it does in mine
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.

I've played about with tyre pressures but it makes no difference.
I need some new front tyres and currently have Pirelli P Zero Rosso's all round, but I'm tempted to get Michelin Pilot Sport PS2's for the front as I've heard they are better on wear and dry grip. I can get them for virtually the same price at Tyre-Universe.co.uk
Would that be okay do you think or should I stick to the same make all round? Opinions?
Cheers,

Perhaps - it's daft to me to mix tyres, buy some to match the ok ones or swap all 4 would be the only acceptable situations to me. You are potentially mixing different compounds, tread patterns, wear, rolling resistance and aged tyres on a 150mph+ car. Your call sir - just not something I would (or ever have done).
You’re right, it is daft. It is not always possible to get exact matching front and rear (some tyres not always available / shortage of that make), as I found out a couple of years ago. Bedsides which, the rears wear out up to 3 times faster than the fronts anyway. Quality is the key[
]. Of course, the best situation is same make and type all round, but this can often be thwarted by unforeseen circumstances.
All valid opinions chaps - not spoiling for a fight, I just would never personally mix tyres. In a former life I was an accident investigator and as far as vehicle accidents were concerned, mixed tyres on any position on a vehicle would always be cited as a concern during any investigation. Most blue light response services have a policy of not mixing tyres at all. My comments about compounds was not about one noticing a difference, rather there being a difference when one had an issue or got it wrong etc. Anyway, mix away chaps - I am out of this one.
Daren, I think Chris' avatar pic will tell you what he drives - think....Cayman! Jon, I have to say that I'm in the Chris camp when it comes to mixing tyres front to rear, but understand and sympathise with your situation particularly since my Cayman seems to eat its P-Zero rear tyres. If you contact your local PC I think you'll find that they'll discount you for part-worn tyres if you replace all four. Jeff
I'm new to Porsches having bought a Turbo in February from a Porsche specilaist. It has Pirellis on the front and Michelins on the rear. The specilaist told me it was fine mixing tyres so long as not on same axle and I've done that with other cars in the past. But I have appalling road noise from the rear on certain surfaces. I've played about with tyre pressures but it makes no difference. So I'd be wary of buying Michelins.
Interesting Riblaster, I was commenting about front tyres and the Michelin's are 1 db less than the Pirelli's, but the rears are 3db more!! And as I know what you mean about the noise I think I'll be going for Pirelli's after all. As I'll have to get N4's for the front I presume they're matched with N3's on the rear, but to throw this into the mix I wouldn't be surprised if that is the same as mixing makes!! Even if the tyre manufacturers say it isn't.
It's new tyre time for me and all four need changing so this question is about choice of tyre makes rather than mixing makes. It's down to Continental Sport Contact 2 (N2) or Michelin Sport Pilot 2 (N3) or Pirelli P Zero Rosso (N4). The car is a 99 996 cabrio with the BBS 18" sports type alloys. I want a tyre that's quiet with the least harsh ride and ultimate grip is not that important as I take things (relatively) steadily. The car only does a thousand or two every year so I'm not too concerned about wear rate either. Any ideas on these three possibilities to help this Porsche newbie? Finally although it's presently got unapproved (for this model) 295s on the rear, I'm going for the 265 or 285. The strict approval is for 265 on the rear but many use 285s. Any idea on this as well please?
Welcome Jon! I've had all 3 on 996's, and I found the Michelins to be the best all-rounder (and the quietest) but the most expensive. 285s were introduced with the facelift cars in 2002, but many people use them on earlier cars. I really don't think it makes too much difference, but 295 is probably a slight step too far, so you are right to go back to original sizes.
I think a lot depends on how you drive the car If you push it a lot and drive high speed lots of the time them you must keep them the same all around But if you just enjoy having a potential 150 mph but drive to speed limits and are a 'sensible ' driver most of the time - mix then while the rear ones wear out would be OK richardjjs
