Welcome to Bamford Rose and another question of the week. This week’s quite “tyring”. Sorry for that one. Tyres! This type at the bottom is the Bridgestone. It’s the AM9 branded tyre V8 Vantage DB9. This is Michelin Pilot Sport 4.
Obviously, the only advice given would be to fit the manufacturers rated tyre. But if you’re on track and you want the best handling experience or you want the best tyre allegedly, it’s definitely in the Michelin Pilot Sport 4. For the V8 and DB9, this tyre sidewall is noticeably more compliant than the Bridgestone. You get a comfortable ride, so except this one is a bit better. It’s much quieter. And then turn in and grip, grip available on this tyre, wet, dry, everywhere, is just far better than the Bridgestone tire.
Why did Aston go Bridgestone? Well, they are part Ford and I think Aston was leant on quite heavily to go for Bridgestone. But as far as I remember at the time someone might like Michelin wouldn’t been interested in supplying Aston or the tyre testing that went into it for the volumes that asked and they’re going to consume quite low volume. Tyre makers weren’t really interested in niche car consumption, so they didn’t want to endorse it like the Bridgestone has done in this case.
In going away from standard tyre or the rated tyre, it’s match or better exceed the load rating. This is an extra load hundred wide tyre. The front and rear tyres, well, they are 92, 94, 96 wide, so Mitchell Pilot Sport has exceeded the load capability.
In terms now are dropping the P Zero on a DBS V12 V, well, when Bridgestone did the rear tyre for V8 in DB9, Aston probably because of that Ford liking tried to get Bridgestone tyre signed off on V12 V, but the extreme speeds, extra temperatures that was running, it used to delaminate and this whole tyre section would just peel off when it was on high-speed test.
Pirelli came in with quite a bit of work, and managed to get a tyre that passed all the sign-off tests needed for an OEM. Nobody now is going to rerun those tests to that temperature or speed extreme on this Michelin. At, what is it, 186, 190 miles an hour in a set climate temperature for a set time, would this tyre pass? Who knows? For that reason, you can’t properly endorse it as the tyre to go to. It has to be an individual’s choice. But how many cars go above 150 mile an hour even in the UK even on track? That’s quite difficult to do.
So, in terms of any risk associated with swapping from the branded tyre, the advised tyre on V12 V and DBS to the Michelin Pilot Sport. Many customers that have fitted the Michelin Pilot Sport wet grip, fantastic grip below seven degrees which is like that tarmac temperature where those P Zero is really struggling at anything cold and the back end is sliding around where the feedback is Michelin wet and cold are much better.
So, on every measurable, apart from the high-speed great test which none can really do, no one’s going to do, then this is the better tyre. Especially, if the load rating is there, then you’ve done your best to make sure that it’s going to pass the load rating. Price, well, I mentioned in Pilot Sport 4, it’s actually cheaper than Bridgestone and cheaper than P Zero. So, there’s a whole lot of reasons for always going for the Michelin than any of the Aston branded tyres.
