Also, those wheels were steel and had a centrally located fixture surface and wheels were not as wide as the BMW ones. It is a long time ago that I did a stint in the lab of a wheel manufacturer and saw the way the mechanic guys tested wheel flexture tolerance using a dynamic rig to see how many flextures it would stand before it broke. This will result in flexture in the alloy when the inside edge of the wheel is impacted and would have needed careful consideration during its design. It is near the outside edge of the wheel and the inside edge is a long way from where it is fixed and has no cross bracing. Not having looked at wheels for a long time, I was surprised to see the wheel is attached by a surface that is so far off center. Something might be made of that in a court case. Thus the damage occurred because they were unable to withstand tyre impacts. In other words, the rims had not come into contact with the road surface. His point was that on the cracked wheels he inspected there was no damage to the alloy rim. I watched a motoring man on the TV comment on these cracked BMW wheels. Not impressed with BMW and will consider reverting back to Mercs' in the future. I would expect to see at least 25/30k on tyres this day and age so will follow the trail!
Wife has now refused to be driven in the car and is very happy with her old Clio! Motor is currently off road to consider the options. They sound good in theory but from a practical point of view they appear to be useless and could endanger one's life. After doing some research, I am very concerned now as there is a familar pattern of disatisfaction with owners of this type of tyre and inherent wheel cracking.
I was astonished to see that with 4.5mm of tread across the tyres the inner edge is bald! I have started to take this up with BMW and Bridgestone but not given much support or consideration. now with under 14k miles and just had the motor serviced to be advised that I need new tyres on the rear. Early last year bought the M3 sport model with 255/30R19 run flats on the rear.
