Hi, I have M3P with stock 20's and just Installed a set of 19"x9" rims with 255/40 19 tires. The overall diameter of the 19" tires are about half an inch bigger then the OEM 20" tires, do I have to change the configuration from 20" to 19" or just leave it as 20" since the the overall diameter of the 19" tires is half inch bigger.
Thanks to everyone who have experience on this!
