But here are the sidewall heights to compare:

Tesla 235/45-18: 4.2"
Tesla 235/40-19: 3.7"

I'm attempting to rationalize that 3.7 is close enough to the e46 that is basically the same. It's a larger diameter wheel too.
This got me curious… The 19's on the Model S take a 245/45R19 tire, which has a 4.3" sidewall, so I'll be going down 0.6 of an inch.

FWIW, the Model S 21's are 245/35R21 -- which has a 3.4" sidewall. Let's hope the extra 0.3" gives pothole protection!
