Morning all.

I have recently bought my first BMW, a 2010 520D SE Saloon. Fantastic Car, but my N/S/R Tyre has worn down very quickly. I have only done around 3500 miles on them, I check the Tyre pressures regular and at 49 years old, My days of over exuberant driving are far behind me. Can anyone help with as to why the Car would only wear the one side Tyre?.

Hi Jamie

Welcome to the Forum

The diff provides power to one wheel normally the one with least traction so one rear tyre often sees more wear due to momentary slip at pull away. Quite easy to do when you think your car produces a little more torque than an E46 M3? 

Also what tyres are fitted and how worn were they when you brought it, if the previous owner had a heavy right foot the tyre on that side may have had more wear before you sat in it.

Some tyres have softer compounds grip better but wear faster, Pirelli PZero on my X5 as an example great tyre but lucky to get 15k 

Enjoy your new Beemer
