Exactly. I had 401 Km remaining on my batter when I picked up my car. As per my request there was no test drive. I drove it about 4 KM on my test drive and when I got back to the tire shop I was now showing 408 on the range remaining. Thinking it might be because they new rims and tires are 5 lbs lighter on each corner? Anyone else experience more range when changing rims and tires. I highly doubt tesla left more range on the table and would of went with lighter rims if that's the case.
