First newbie question of many!
recently bought a 2008 3.0sd and have read a lot of stories about tyres causing issues. Currently running 235/45/19 pirelli p zero rosso * marked on the front (6.5mm tread) and 255/40/19 pirelli p zero rear - no * (4.5mm tread). The only thing is they both have different tread patterns. Is this likely to cause issues in the future or am I over thinking it? Seems to drive ok, maybe a bit hesitant on gear changes through 1st 2nd and 3rd although this is my first x3 and first auto so hard to know. I've found a discounted pair of p zero rosso * for the rear so thinking about changing to be safe. Will still be a slight difference in tread depth but interested to hear other peoples thought and experiences.

Thanks
