Tyres on the new M3 (Autocar test in 2002)

I remember reading Autocar last year (and it was referred to in this week's edition) about the tyre test they did with an M3.

They said that different tyres had considerably different characteristics and they put the Michelin Pilots near the bottom of the table.

I noticed that the M3 at me dealer had Michelins and wondered:

What tyres have other people got ?

Any problems with those on Michelins ?

Is there a choice ?

Should I ask my delear to see if they can fit something different ?

etc etc

It may be that Autocar don't rate the Michelins as they make the back end of the car 'too' stable (fine by me - I don't want to write the thing off soon after leaving the showroom !), and they prefer a bit more oversteer.

Any thoughts, please let me know.

Cheers

Anyone got a copy of the Autcar test from last year - I pass on my old copies to a mate who has got rid of this edition suicide.gif

I'm sure that I won't notice much difference between the two, but if they got that different reviews then it might be worth my while trying to get Contis instead.

Couldn't find the article, however, I found some personal reflections from a poster on www.bm3w.co.uk

I've had experience of Bridgestone S02s on the track but only with an E36 M3 Evolution. They were fantastic in the dry and unbelievable in the wet. The only minor criticism would be that they don't last particularly well on a very hot track (i.e. they melt).

While I have 5 mins, here's my opinion on various road tyres for the track. Some of these will be opinions formed while I was still a novice but still worth reading:

Bridgestone S02 - Standard sizes (225/50R17, 245/45R17)

As above ... excellent dry tyre and the best I've ever tried for wet driving. Melts on a hot day. I was never a good enough driver during E36 ownership so can't really remember understeer characteristics.

Conti Sportcontact M3 - Standard Sizes (225/40R19, 255/35R19)

Lots of understeer and pathetically weak sidewalls mean lots of shoulder wear, especially on the front nearside tyre (on clockwise circuits). One harsh-surfaced airfield day on Contis once had me down to the canvas/wire on the front tyre (although I wasn't doing a great job of quelling the unersteer that day so partly my fault). If you use these on the track, suggest LOTS of extra pressure.

Michelin Pilot Sport - Standard Sizes (225/40R19, 255/35R19)

Hard-wearing and even-wearing but average and (importantly for track driving) overpriced. Less understeer than the Contis but not as good as the Pirellis. Best tyre for lasting the longest IMHO. Reasonable grip.

Pirelli P0 Rosso - non-Standard Sizes (245/35R19, 275/30R19)

More grip than Contis or Michelins and less understeer (partically due to non-standard sizes I suspect). Made of blu-tak.

... and for reference ...

Dunlop D01J Formula-R Semi-slick - Very non-standard Sizes (235/40R18, 235/40R18)

No understeer. Tons more grip and very hard-wearing. Apparently useless in the wet

I've run the P-zero's (245/35-19 front and 275/30-19 rear combination) on my last 2 M3's and they've always proven to be fantasic in all conditions. Remember this test was conducted with Pilot Sport 1's and not the new, much improved PS2's.

Here's a synopsis of the Autocar tyre test:

The M3 was some four seconds quicker around Michelin’s wet handling ciruit with P-Zeros fitted than it was on Pilot Sports.

Here's the results:

Dry handling - Pirelli wins

Wet handling - Pirelli wins

Straight aquaplaning - Michelin wins

Aquaplaning in a curve - Pirelli wins

Wet braking - Pirelli wins

Rolling resistance - Continental wins

Noise - Michelin wins

Verdict - Pirelli win.
