I had different combinations of very low profile z-rated summer and all-season non-runflats 18’s and 19’s on the bmw and mb both with sports package suspension. The quiet ride with minimal road noise and firm yet still smooth suspensions are the primary reason I buy these cars over a Honda Accord. Hopefully the model 3 is quieter than an ICE 3 series or C class. I think the extra floor and wheel well insulation on German lux cars is a difference maker. Hopefully someone with similar experience can give some more definitive advice before time for me to configure my car.
