Interested to know myself, but I think this was specific to the PSSs, may not be the case with PS2s, so would be good for someone to confirm as far as the latter. The PSSs are a lot more 'square' than the PS2s so perhaps that has something to do with it?

@robertm aren't you worried the 265's in the front will be problematic? Alternatively can you confirm 'trying/running 265 front without issues? Sorry to plead ignorance on this, but what makes you say 2nd gear is kind of a joke? Is it because of abundant wheel spin or because of general rear tire wear (even without frequent spin)? or else ... |

As rear grip is not a DD problem (yet). I'm thinking of running 265 square as that is easy to rotate and provides some front curb protection.
any thoughts on/beyond front fitment? |

I haven't switched tires yet so I can't confirm anything. I'm hoping someone else will be the guinea pig. I'm also thinking if there is just a slight rub on the front then probably some 5mm spacers will solve the issue. |

So will 255/35/19 rub on stock suspension or not with PSS?? I keep seeing people say yes it will and no it won't. Who actually runs this setup and do you have any issues? I was looking at going with 255/35/19 and 295/30/19

I have 245/35 19s (stock size) PSS on my car's front and it almost rubs, in fact probably did rub a few times already. There is literally 0 clearance with stock wheels and suspension for anything larger diameter than 245/35. Stock size PSS has 25.8 inch diameter whereas 255/35 19 has 26.0. So, there is no way that 255s won't rub, not a chance. But will probably do this only at parking place speeds at full locks. Trimming the liners a bit can solve it for you.

That whole comment is unclear anyways. It says
"(this can only happen if you lower your car too much, at stock or 1" lowering there is not enough compression travel for this to happen)" ?? Which part? So I would assume that 255/30 would be ok though? |

Sure it would work, but the overall diameter is too small when compare to a 245/35.

+1. Even 265/30 is smaller in diameter. With those you won't rub yes but will add more in the already big wheel gap. Your car will look like a SUV at the front.

How important is the diameter change on the rear? Does the increased O.D. stagger effect the TC and MDM accuracy? This question would apply to square setups also . . . any experience with this?

Sorry, but is someone willing to do a google docs or just a full listing of sizes of PSS for our 1M and just say beside the sizes "Rubs" or "Not Rubs" or "Not Confirmed" or something like that. There's too many threads and it's a little confusing.

My reasoning with the 295's in the back is because I'm going FBO and probably meth. 265 isn't going to work so good with that I doubt. I'm just concerned with going that big in the rear but sticking with 245s in the front.

Here what I read from tire rack site about the PSS specs, just the essential data, for the rest go for http://www.tirerack.com/tires/tires....eMake=Michelin Here you go: Stock tires vs. what fits nearest: 245/35 19: 93 Y 23lbs. each 8-9.5 inch rim range 25.8 inch overall diameter 807 revs per mile vs. 275/30 19: 96 Y 26lbs. each 9-10 inch rim range 25.6 inch overall diameter 814 revs per mile 265/35 19: 98 Y 25lbs. each 9-10.5 inch rim range 26.3 inch overall diameter 790 revs per mile vs. 295/30 19: 100 Y 28lbs. each 10-11 inch rim range 26 inch overall diameter 799 revs per mile Hope this helps.

Speaking of Tire Rack, why don't you guys all log in a request for PSS in a 285/30/19 fitment. That is the exact fitment on the M3 GTS in Europe (which of course rides on the same wheels as our cars), and it has 255/35/19 up front.
I've talked to TR a few times, they said if enough people show interest they will forward it on to Michelin. Per TR, the 285/30/19 tire is quite popular with the Corvette guys already, and I reckon between us 1Mers and M3ers, we can hopefully put this on Michelin's radarQ

IMO there is no sense in upgrading the size of the tires if you are going to run something like a dw or v12.
A better quality tire like a re11 or ad08 or rs3 in a smaller size would perform much better in all aspects. Plus, the dw / v12 already have softer sidewalls than ps2 and especially compared to the re11 style tires. BMW wheels run a little stretch with a 265 on a 10 inch wheel and a 245 on a 9 inch. The stretch helps stiffen the sidewall to aid in eliminating body roll and increasing cornering stability and grip. Going to a softer tire with less stretch will result in substantially deteriorated steering feel and cornering abilities. My car is cobb stage 1+ and moving from pss to re11 in stock sizes was just what the dr ordered. Performance wise, my car does not need wider tires. Great grip and traction, and tons of steering feel and stability on the track and street. I couldn't beleice the difference on the track.

If so, what would be your choice for street/highway/back road driving and no track or competition, and why? Thanks.
