Hello Norris,
Thanks for your response (seeing it quite late  ). Another question, if this is fine with you - have you had any issues with this size? What are you setting in the iDrive as tire size and overall how is the car behaving?
Thanks! |
I wanted to report back to you on the tire pressure setup. I noticed my rear winter tires were wearing out more in the center. Which means they were over inflated. I realized that increasing the profile size on 20" tires means you have same tire height/profile as 19".
If you're running 20" wheels with 5% taller profile, setup the air pressure as if you have 19".
When I have my 21" wheels I would use the 20" recommended tire pressure because than it's profile of 35/30.
