This seems to be a bit of a theme lately on the forum so figured I'd take advantage and ask my question as well! I have the AWD Model 3 with 18" Aeros on order since late May and am not a tire/wheel guy prior to this purchase by any means so wanted to ask the experts if my entirely Internet based research is sound or way off base. My current plan: Purchase the TSportline 18" TST wheels and pair them with the Michelin Pilot Sport 4S 235/45ZR18 tires for what little of the summer/fall will be left. Purchase snow tires (probably the Michelin X-Ice XI3 235/45R18 tire) and have them installed on the Aero wheels. Any flaws in my tire size choices? Should I get 19" summer tires/wheels for performance reasons or are 18s the sweet spot still? Any other tire models I should be considering instead? Anything else I'm missing? Thanks in advance!
