I've had numerous cars over the years ranging from Camrys to a Mazda 3s to a Jetta Sportwagen TDI to an Audi A4 to Outback Limited. I'm by no means a "corner carver" and just simply drive from Point A to Point B. Although I've only got about 2200 miles on my SR+, I was checking out tire options for when that time [eventually] comes.
With my previous cars, I've ALWAYS gone with the cheapest tires with good overall reviews (and brands that I've used in the past) with good results. Given my usage patterns, I've never really noticed much (if any) handling/performance/efficiency hit compared to what came with the cars stock. I've had good luck with Hancook, Barum, and Sentury on previous cars (our Subaru is currently running Sentury all-season tires).
I know that the Model 3 is a bit different as it comes from the factory with low rolling resistance tires (I have the 18 inch wheels). So I was wondering for any of you SR+ owners out there that have gone with cheaper, non OEM 18-inch all-season tires, what kind of ride/efficiency hit (if any) have you taken with the switch?
I can get Sentury or Milestar 40,000 mile A/S tires for $83 and $91 respectively. The OEM Michelin MXM4 tires around $240/each IIRC.
