I have just purchased a 2003 E60 530i - my 1st BMW. Has model 124 wheels (front 245/40R18 rear 275/35R18) fitted with Bridgestone Potenzas. I gather there is no rotation option here....
What's the general view of expected lifespan (kms) of these tyres? What are the suggestions for wheel balancing - frequency etc. to prolong tyre life?
Also - how do I know whether this vehicle I purchased (privately) has sports suspension (previous owner doesn't know..). Ride seems quite firm but good.
