Hi Charles, I agree that the Michelins seem much better value for the B10v8s too, but when I paid more for the Contis, they were the only ones I could find anywhere and I was getting desperate. I will order Michelins well in advance next time and even store them for a while until I am ready as I will need them by June I reckon. Good to see others have had a similar experience, thanks for a good thread. below is a pic of the first PS's at 28000 miles on the front, rears quite similar wear

Again, this contributes to the original point of the thread.

Every car/variant seems to use tyres in different ways and so there is no simple formula for assesing cost benefits against performance benefits.

I've been amazed that B10 V8 owners are seeing mileages on the rears in excess of what I achieve on the B3S - particularly as I feel that 20k is a very good duration for 300+bhp through the rear wheels.

That said, I would urge owners to try and establish the costs for their cars and to assess these against the performance they get from different rubber. It's an inexact science, but with the data that is beginning to build in this post, oweners should begin to see a pattern and take advantage of information shared by others to make informed choices.

My B3BT has now done around !2k miles and the rears are about half worn. My previous B10 only managed 12k on a set of rears.
The B10 was used every day for work with lots of shortish trips and plenty of town use. The B3 is only used on long trips and doesn't do hardly any town work.
I wonder if this is one reason why the PS2s are lasting longer on the B3?

Our D3BT never does anything less than a 30 mile round trip, at mostly national speed limits(ish), and we use it for long runs to Devon (200 miles ea way) and to either Cardiff or Newport when it's due to be fettled (100 miles ea way). We don't have roundabouts in any big way here in West Wales, and not too many traffic lights, either. Basically, rural, quick, good quality (sorry boys) roads. That's why we don't 'get' the rear tyre wear rate being so high. Maybe it's the champagne I keep pouring on them for the 1/4 milers :lol: Oh, and our Mini still has 3 original tyres on it at 27k with 3mm left on each (4th was punctured). That's how hard we are on tyres!

That's why I am puzzled about our rear tyre wear....have been since it became evident. Lots of 300hp+ cars on here get much better mileages from theirs than we (and other D3BT owners) have. Maybe a torque overload issue? Slightly bizarre. Anyway, back to thread before the Mod gets me.... 8)

Ade,

Is there any correlation between switchtronic and manual cars, as the switchtronic cars seem to be easier on tyres? Just another thought.

I might be able to give my opinionand views on this question soon.
My last D3 BT was manual and covered nearly 8000 miles when I swapped it for the D3 BT switch.

The manual D3's Michelin tyres were looking almost 'as new' when it went back to Sytners.
My journies are widely varied. I live in Milton Keynes - so LOTS of roundabouts. Some journies are 5-10 minutes (30mph and 70mph roads in MK), some 150 mile days (consisting of A roads, Motorways and back roads) and some 200-300 mile days.
Based on what I had seen I would easily have expected 25,000+ miles from the rear Michelin tyres and hopefully at least 20-25,000 from the fronts (roundabouts here kill front tyres).

The Switchtronic is now on 2500 miles - same journies and again the Michelin tyres still look 'as new' front and rear.

My driving is pretty subdued and steady although the occasional 'blast' is not unheard of :D

When I get to 8,000 miles I'll have a better gauge on whether the switchtronic is easier on tyres, however as it stands at the minute I would expect that it is better on tryes (at least in my case) as I am noticeably aware that I drive gentler in the new D3 switch than I did in the manual.

I can get 265/35/19
Conti's for £230 each
Bridgestone's for £250 each
Pirelli's for about £270 each (wife has 18" P-Zero's on her A4 and they are lovely)
and Michelin's for £280 each

So assuming the Michelins get 10-20% higher mileage then they seem to be the tyres to go for.
Although I do now have a sweet spot for the Pirelli's and found the Bridgestones (again 18") on my E46 excellent too.

Hmmm still no clearer :roll:
current : D3 Bi-Turbo no: 230 Switchtronic in Alpine White, Dynamic Alloys. privacy glass.
previous : D3 Bi-Turbo no: 241 manual in Montego Blue, Dynamic Alloys.

Car: B10 3.2
Tyres: Pirelli P zero asymterico (or however its spelt) - rears just replaced after 17000 miles with Falken FK452 xl.

I'm quite pleased with these so far. Quieter than the pirellis and half the price. Plenty of grip.

Current milage, 91,000. Still on second set on Mich PS2's on front. just replaced Conti's on rear with new Michelin SuperSport (look very similar to PS2) at about £600 a pair. Contis only did about 10,000 but gave good grip almost to the wear indicators.

So again, Michelins greater wear offsets price.

Hi all

After 24k my D3 MT needs a couple of new rear boots. Currently still on the original 265/30/19 PS2's.

Just reading through the thread and no mention of Goodyear F1's be it the older GS D3 or asymmetric.

Has anyone tried Goodyear on their Alpina?

I've used GS D3 on three or four previous cars including currently on the mrs's R56 Mini Cooper S and they are brilliant. All were on hot hatches though.

However the Asymmetric 2 has just been released but getting hold of them in our size maybe another thing.

More details here:

Some intereting points raised re Mich PS tyre wear on the E90 Alpina. The wear rates on the petrol and diesel variants seems quite different with the derv Bi-turbo seeing the higher wear rates. Could this be an issue as to how the power is delivered and the difference in torque curves?

Also, the different wear rate between different models is probably down to the dynamic set up of the cars and how much downforce is generated.

Any thoughts on the Eagle F1's?

I've just managed to source a pair of rear PS2's for 300 a pop. So tempted to stick to them.

Cheers
