Based on the cars computer after I changed the wheels from 19 to 21, the max range showed as something like..379 I think? Im going off of memory.
But for me, the max range really isnt a factor (this is my third tesla). I work from home, and when I dont, my commute is 10 miles. On weekends I may do a max of..25 miles each day at most. Longest driving trip I take is about 170 miles each way. So at most, I may need to stop at a supercharger for 10 mins (which there are plenty along I95/my route on the east coast). So for me, long range hasnt been a requirement for me in the last almost 4 years of Tesla ownership.
