Tyre issue

[Osinjak]

Annoyingly, I need to change my NSF tyre. Wear across the two fronts is equal with 4,5 and 4mm (inner, middle, outer). Head says replace both, wallet says just the faulty one, car is a 3 Series xDrive. Thoughts?

I think because of the x drive, you need to be careful about tyres and keeping them as matched as possible. Can cause problems otherwise.

Maybe you could get away with one on this occasion as the difference might only be a few mm, or maybe a part worn that matches the other 3? I dunno, one of the reasons I wouldn't want an AWD in the UK.

Hence the question really, if it was RWD I'd just go with a single but as it's xDrive I'm a bit wary. Just not sure how much, if any, difference 2-3mm will make.
