Has anyone experimented with lower pressures.

I recently switched to Pilot Super Sports. Much better but I am considering dropping pressures from the recommended 36F and 38R.

I think these are too high.

For comparison the Ferrari 599 which weighs the same and has a heavy V12 up front runs at 30-32 all round on the same Michelins.

Other comparable cars all seem to run 30-34 all round.

Any thoughts
I run my 07 Vantage with Michelin PS4s at 2.2 bar (32PSI) all round (cold). No Issues.

Old thread, but bumping this one.

In a few months, I need new tires (tyres?) on my DBS. Did never like the OEM Bridgestones, and got Continental SC6 (and before SC5) that I found much better (in handling, in [less]noise, etc).

When buying the SC6, I considered the Michelin PS4S, but they were not available in the right sizes back then. but now they are.

Anyone here good (or bad) experiences with the PS4S on a Gaydon V12 car?
Have very good experience with the PS4S on my other car (S63), found it a huge step forward from the PS3, but of course every car is different, so therefore the question here.

Big thread in this over on V12 vantage subject.

PS4s are superb as far as I’m concerned

I switched recently to PS4S from the standard Aston fit Bridgestone tyres on my V8 Vantage.
They take some bedding in and I was warned about this by the fitter.

Of course I didn't listen to him and withing a few seconds of jumping in and driving, I had the car squirreling down the road. Now after several hundred miles on them I can say they are more compliant the Bridgestones seemed rock hard by comparison.
They are marginally quieter and once scrubbed in the back end feels more secure under hard acceleration coming off a bend or roundabout. The Brisgestone would often let go quite easily in this regard.

The curve ball is the new Bridgestone Potenza Sport, which looks to at least equal the 4S in tests, beating it once and coming a close second to it in the second test:

If owners want to keep a Bridgestone on the car it's a very good option.

I think there is little help in comparing a seven year old worn out tyre with a brand new next generation tyre. Everybody can imagine the outcome...
At least you should not draw conclusions regarding the brand based on such a comparison.
Since no one is really trying out same generation tyres on one car within a brief period of time and can provide meaningful information we should simply stick to what professional and at the same time neutral tests can reveal.
Bridgestone, Continental, Michelin and Pirelli all are premium brands which produce tyres of similar performance. The last time I checked, only Continental (SportContact 6) and the new Bridgestone Potenza Sport were available for both the V8Vs and the V12Vs. The Michelin PS4S for the V8Vs only in the US. With regards to the old Vantage 2005 - 2018 Pirelli does not offer tyres in the correct dimensions. But for the Vantage 2018 - today they do offer the excellent fourth gen Pirelli P ZERO PZ4.
I don´t see any reason to hype any brand here - simply because the performance of these tyres are so close.
If you intend to use your car in rainy conditions - which may happen in the UK - then you should consider that the Michelin is the weaker performing under wet conditions compared to the Bridgestone or the Continental.

I just put new PS4S on my V12V and it has transformed the car. Highly recommended

I think this applies to any new tyre on any car; I was told it could take c 100 miles to bed-in the new Dunlops I stuck on my E reg 911 way back in 1992.

Fresh tyres need some running in.

During manufacturing a technical lubricant is applied to the injection mould. This lubricants makes fresh tyres look so shiny. In addition the surface needs to get a certain micro roughness to have the perfect grip. So, how long does this take? Obviously that depends. If you choose the approach of BiggaJ, you are probably done after 10 hard accelerations and brake procedures. The same, if you choose to drive your new replacement tyres on a trackday. One or two laps and you are fine.
If you treat the tyres extremely careful and start out during rainy weather you will possibly need 200 miles to have the lubricants washed off.
The more you push the faster you are done...

Please note - this is a comparison of the Michelin PS4S against the previous generation Bridgestone - which is a bit misleading. The current Bridgestone Potenza Sport is at least on the same level as the PS4S...

The S001 was launched about 12 years ago too!

I have Pirelli P Zeros on my DB9 GT, the rears need replacing but the front tyres have plenty of life. How do these Pirelli tyres compare with the Michelin Pilot Sport 4S & Bridgestone Potenza Sport tyres?

If I move away from the Pirelli tyres, could I just replace the rears for now or do I need to change all 4 tyres for Michelin or the Bridgeston Potenza?

I would have thought for standard day to day driving it wouldn't make any difference but if you frequently drive the car close to its limits then there could
be issues.

I would recommend to change all four tyres.
Mixing different tyre constructions and different compounds is no good idea for a £ 100.000 GT / sports car.
Under certain conditions the new tyres will have significantly higher traction than the old tyres which indeed may be dangerous.
Are the front tyres the original ones from 2016? Than they will soon reach their age limit anyway.

Which version of the P Zero? If it's the old one, you'll notice significant improvements moving to a newer tyre, especially if it's the old OE version which likely hasn't changed since the cars initial development.

Thansklf ri the feedback guys.

Just checked: the tyres are dated 2015; the car was registered in May 2016; I bought it in August 2019; it has done just over 14,000 miles; I will go for new tyres all round.

Anyone have a view on Bridgestone Potenzers vs. Michelin Pilot SP4s fr a DB9 gt?
