Firstly, I would not go to anywhere that isn't recommended by others or that specifically deal with Wheel Alignment....Protyre are one such company that are well versed (and trained) in 4 Wheel Laser Alignment. The bushes are difficult to diagnose when only marginally worn but if the alignment shows it to be out on the rear suspension and you haven't slammed into any kerbs then chances are the bushes are worn. Finally, I would not imagine that BMW would entertain bushes under warranty as they would be classed as 'wear and tear' but worth a try I suppose Cheers, Trevor

Since noticing your response and statement of tyre wear, I would wholeheartedly agree with Dave's comment about worn bushes and misalignment of the rear wheels. In general, the camber could alter and marginally affect the tyre scrub but if the rear toe is out then this would grossly affect tyre scrub which could explain the uneven wear across the tyre and also the excessive wear on the whole of the tread. Can only recommend taking to a 'reputable' firm that not only has the pucker equipment (Hunter) and also the personnel sufficiently trained in carrying out the checks (e.g. starting with any adjustments at the rear first). Maybe worth dropping it in before bush replacement (If necessary) and get some figures to confirm the tyre wear and then drop back for any required adjustments following repair.

it's more than likely to do with water dispersal...method used to shift the water from between the road surface and beneath the tyres

Hi Rob....try this link https://applications.castrol.com/oilselector/en_gb/c/search?_ga=2.164205500.2057647797.1538559598-1911328056.1538559598

Sounds like it is due to power being delivered through the rear wheels as opposed to any abrasive road surfaces or similar...if that was the case then the fronts would also be worn the same as the rear as they've done the same distance. However, it is not making the assumption, as you have already stated, that it is your driving style, more a case of somehow the power delivery being more aggressive than it should be? I know this is the case with motorcycle tyres where you can rip a rear tyre up in just 2k to 3k miles with too much of a handful on the throttle. Therefore, I wonder if there is an issue with the drivetrain programming which could be causing this issue?....just a thought. Technically, you should have the same rolling circumference on all the tyres to run with the X Drive

Hi William....welcome to the Forum Hopefully, there should be a supply of these parts on eBay but you are welcome to place an advert in the For Sale / Wanted section of this forum, which may get some responses. Good to have you onboard Cheers, Trevor

Glad your car is sorted now Maggie and also that it wasn't too expensive in the end. Great analogy Dave....will have to remember that one 🙂
