So, could I rotate the tires from side to side if they're not directional? Also, for the OP, why not consider the Toyo T1R? It did pretty well on the Miata comparo. They tend to be pretty light too, at least the T1S were very light.

You're seriously basing your decision on Consumer Reports???

Yes you can rotate your tires side to side with asymmetrical tires and still maintain the same wet weather traction. Technically you can do the same with directional tires if you aren't driving in the rain.

I've paid to have directional tires dis-mounted and then remounted after rotating side to side and it definitely prolonged tire life since there was a good amount of negative camber.

It should be a very strong indicator. The tire can't really "feel" the cars weight it can only feel the pressure and with appropriately sized tires the pressure in the contact patch on a lighter car vs. a heavier car (given that the heavier car will generally be running a wider tire) will be close in area.

I'm thinking more about sidewall strength and how the tyre reacts to lateral loads, a heavier car will always stress sidewalls differently to a lightweight car. Suspension design is also significant...compare how the E46 M3 had poor control over the loaded front tyre in extreme cornering that would cause a PS2 to "roll under" putting high wear onto the shoulder, something that does not happen with PS2s on the E92 M3....so whereas a tyre with a very stiff sidewall might give good numbers for the E46 M3 it doesn't follow that the same tyre would be appropriate for the E92 M3 which doesn't need such a high level of sidewall stiffness.
For me the most important property of a road tyre is not how much grip it has or how crisp the turn in, its how much confidence it gives you. I don't want some ultra stiff sidewalled soft compound semi slick that will launch you into the scenery without warning the moment you exceed its limits...I'm happy to give up some ultimate performance for a tyre that is benign on the limit and even more so when you have exceeded it. I always liked the OEM Continental tyre on my E46 M3, they weren't great when new but once worn down to the "sweet spot", around 5mm of tread and with a few extra psi, they gave a great feel to the car and a high level of confidence in what the car would do up to and beyond the limit of adhesion. I have PS2s on my E92 M3 and I do like them but unfortunately the E92 M3s suspension does not communicate as well as the E46 M3 which is a shame, I suppose its the sacrifice you have to make to get the increased front end grip. |

That's why I replaced my OEM PS2 with PS2s after considering this for some time. (I caught a special and saved ~$200 I think, but still expensive). A street tire is about all around performance for me. I don't care about a stiffer sidewall or a little bit more grip when I'm just driving around. They also serve as my wet track backup, and I know they do well there as well. I also agree that serious dry performance => dedicated track setup.

Sorry if it's been posted here....and i missed it. But does anyone know the exact weights of the OEM 19" PS2s?

Not solely, but there ratings seem to reflect what is being said here.. PS2 and PZero rated high, The P-zero Rosso and Nero which are not seen as great are low on their list.. just another data point. I buy a lot of stuff using their rating and have always been very happy with what they recommend.

With the M3, you'd be wasting you time since you have to do front to front and back to back (due to different sizes), and the wear pattern wouldn't change... unless you dismount the tires and remount them with the 'outside' mark inside, but tires look like $hit with the inside side out (same thing with directional tires). That's why for practical purposes staggered setups cannot be rotated.

Here is an interesting video from a well know UK magazine; Autocar comparing:
1) Goodyear Eagle F1 Asymmetric 2) Michelin Pilot Sport PS2 3) Bridgestone Potenza RE050-A 4) Continental Contisport Contact 3 5) Pirelli PZero Nero / Rosso 6) Dunlop Semi slick. http://www.autocar.co.uk/VideosWallp...=228551&Mode=B (Click on "watch now") Having used the Goodyear tyres on my E46 M3 I was quite interested in the results. Shame Goodyear don't seem to make a suitable rear tyre size. Last edited by SenorFunkyPants; 06-06-2009 at 02:56 PM.. |

Got a screw right at the edge/corner of my rear PS2 today that makes it non-repairable Now I have to decide if I should replace with another PS2 or replace both with RE-11s since the other tire is near its end. Would you say the RE-11s are 'worst' than the PS2s in threadwear?
