DB11 / DBSS tyre choice

[flow99]

New to Aston Martin and looking for new tyres for my DB11, which is now on the DBSS 21" forged wheels. Pirelli PZero's seems to be the standard tyre choice, but anyone running Michelins on their DB11 or DBSS?

Have come from years of Porsches and always used Michelin Pilot Sports or Cups depending on the car, and really like the products.

My DBSS has the stock Bridgestones, which have worked well. When it comes time to swap, I'll probably switch to Michelin Pilot Sport 4S' if they are available in the right size at the time. I've had good experiences with the MPS4S on my other cars.

that's my thoughts ntlr, so will check with my tyre supplier for sizes

Would love to see a picture of your DB11 with the DBSS wheels.

My DBSS is on the Pirelli P Zeros, but have hardly any experience seeing as I don't drive it in the winter or wet.

Here you go. One when just fitted so nice and clean, and another in the wilds of Exmoor

Very nice.

Just refreshing this topic. I have been always a big fan (and user) of Michelin Pilot Sport 4 S. But it seems that the latest generation of Pirelli P-Zero aka PZ4 is a decent step up (my impression based on driving the DBSS).

Gread colour :-) (I might be biased)

Looks like China Gray in the showroom?

Great colour :-) (I might be biased)

Beautiful car, DBS wheels look great. Any rubbing issues with the fender liner?

Yes, China Grey, think its a great 'colour' for any Aston

No rubbing at all. There's plenty of room and would drop the ride height slightly if suitable springs were available.

That looks very good - Sir !

I will get my wheels painted in Porsche white gold metallic next week.

I'm running Michelin PS4 on my DB11, The Michelins are a significant improvement on the OE Bridgestones, much more grip in all conditions and a pronounced reduction of the traction problems in the lower gears (on dry roads). Far more secure and confident cornering, I don't know why they aren't fitted as standard. I also use PS4 on my V8VS.

Which variant are you running? This Topic came up on our German Aston forum and now I'm even more confused since it started a discussion about which specs to use. When you consult the Michelin tire finder it will come up with MO1 for the DB11 which is a Mercedes spec. In the end it would make sense to use the one developed for a car with similar weight distribution, but it's hard to find out which one that would be?

Is there actually any science, behind all the different variants of the same tyre ?

Could it be, that marking a tyre as being the only one to use on one make of car, is a clever way of selling at a higher price ?

Note - I do not anticipate confirmation of that, from either a motor manufacturer, or a tyre maker. -

Yes I believe there is a science. No, it's not just a clever way of selling tyres at a higher price. And no, I don't and never have worked for a tyre manufacturer.

As far as I understand it, a premium car OEM (for it is usually only those guys) will select a tyre manufacturer to supply the original tyres for a new model, usually after a competitive tender process. The OEM's chassis team will select a basic tyre from the tyre manufacturer's range that suits the model under development (in reality, the type of tyre will probably have already been selected before the tendering process so the tyre suppliers know exactly what they are bidding for). The OEM chassis and vehicle engineers may then work with the selected tyre supplier's technical team to "tweak" the formulation slightly to enhance some of the characteristics they are after for the model or to better match the car's chassis set-up: for example, they might choose to alter the rubber formulation slightly to reduce noise but sacrifice a little ultimate grip, or vice-versa - but the tyre will still be fundamentally the same as the tyre model on sale to the public in terms of speed and load ratings, so could be fitted to any model that takes that particular tyre size.

For example; if you look at the snip I've taken from the Camskill site for Bidgestone 285/35 ZR19 you'll see three unique identifies, two AML and one Ferrari all with slightly different noise, fuel economy and wet grip ratings. I believe this reflects the tweaks each OEM has made to the basic tyre. Happy to be corrected if someone like jon- is reading



Edited to add
jon- covers this topic on a BMW-tuned PS4S for the M3 vs the standard PS4S in his video here. I was surprised at the level of differences

He also covers the issue of OE tyre technology getting old and possibly less appropriate in the dedicated tyres as new tyre technologies come along in this video
