As for your comment on the Turanza's, yes you are right & I would go far as to say it is correct in what seems to be 90% of the cases of those who have or had those tyres on the car |

Hi all
I'm running the Bridgestone's on my 330i. I've got 40000km 25000 miles. I'm just about to put my third set of rears on the car (staggered 255 rear 235 front) I'm also having the issue with the center of the tread wearing out leaving loads of tread on the shoulders, as a matter of fact the shoulders aren't even worn down to the tread indicator. I've played around with the preassure but it didn't make much difference. Recommend preassure as per the door jam is 2.7 bar. The set I have on the car at the moment I ran at 2.35 bar and they still wore out in the center. 90% of my milage is on the highway. I've been back and forth with BMW and their official stance is, wait for it...this is normal. Just wanted to put my two cents is, I will most certainly be going with another brand for my next set. Thanks for all the advice in the above thread. |

With regards to the speed, I must admit that a fair amount of my driving is moderately high speed. |

As promised, update following my last business trip before Christmas.
Mileage 10330, Fronts 2-3mm, Rears 3-4mm. Wear rate has slowed considerably over the last 1000 miles or so. Still not great and will be swapped for CC+ in January This is quite an interesting read on the tyre reviews website from Michelin which could explain what I am experiencing. https://www.tyrereviews.co.uk/Articl...res-at-3mm.htm |

Been following this with interest - I'm wondering if it's a geometry thing. My car is in the dealer next week for a couple of things, but one of which is to check the wheel alignment, as the car just doesn't feel right at speed - I'm having to hold the wheel slightly to the right for the car to track straight, and it just doesn't feel steady at all.

Occasionally I have to steer slightly to the right but this is due to road camber. If you have a clear single carriageway road in your area, try moving over to the right and see if you need to steer left. |

My own experience, if a car doesn't track straight on the crown of a road, there is something wrong, either in the alignment, or the tyres. Sometimes swapping front wheels 'side to side', (take care in fault finding if they are directional), shows where the fault lay. |

It could be that run flat tyres amplify this effect as there is less give in them, just a thought. Hope you get back on track soon |

Simply put, the tolerances of pressure/temperature setting, is more critical with run-flats. 2psi (0.15bar) can make all the difference to driving precision. |
