BMW Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** you can downsize to the tires you mentioned without affecting the gearing. The 19" tires are within 1.5% of the old tires in diameter. You will not affect the gearing.
Hi Robert, can you post your vin number for me?
Well, when I enter your vin number it only gives me 20" wheels as an option. When I look up the brake calipers they only apply to the 4.8 and the 4.6 engines. It's possible that the calipers are larger and they may interfere when installing 19" wheels. I suggest that you test mount a 19" rim to see if you have the clearance. Originally I was concerned about the gearing. I hadn't considered clearance.
You're quite welcome.
