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 🙂
