Quick question regarding my 2017 GLC43 AMG Coupe. I ordered the factory 21" wheels with summer tires. I plan to drive my vehicle during the winter and wanted something more appropriate for those conditions. My dealer has a set of 20" AMG multi-spoke wheels w/ Pirelli Verde Scorpion that were a take off, basically brand new. I am looking to purchase these for the winter driving conditions but have one question. It pertains to sizing, my current setup has a staggered wheel sizing. The set at the dealership are the same for all 4. They are 255/45R20. Will these work? The dealership say they will, I'm just a little concerned due to the sizing difference. Any help/input is greatly appreciated. Thank you.
