I'm a newbie to the BMW world, but not to the car enthusiast world. I just bought an '88 750 iL yesterday with 138,000 miles. It needs a lot of little things repaired or replaced on it. One of the things it needs is a new set of tires. From what I've been able to tell, the stock tire size was 225/60/15. Currently, the car has BBS wheels with 225/50/16 tires. That means that the current tires are over .75 inches shorter than the stock tire height. Unless the original owner had the speedometer corrected to account for this tire height difference, the odometer shows more miles than the car has actually been driven. I would like to get back to the correct overall tire height. I would like to go with a wider tire at the same time. I'm considering mounting a 245/50/16 on these BBS rims. Can anyone tell me if this tire width will cause problems for me? Will I get tire rubbing? What is the widest recommended width that people are getting away with on these cars? Any help is greatly appreciated! I look forward to learning much more about my new (to me) 12 cylinder car. :)
BTW, the car has some ground effects kit on it that the seller told me was an optional package. Does anyone know anything about this package? Was it most likely a dealer installed option? Did the black 16" BBS wheels probably come as part of that package?
