You could easily switch to a high (but not quite extreme) performance tire like Continental ExtremeContact DW in the stock 245/35R21 size, which would run you only a little over $1000/set for a much better cost per mile without compromising performance to a high degree.
Or you could switch (maybe another Tesla owner would trade) down to a rim size with a more reasonable sidewall profile. I frankly don't understand the trend towards lower and lower profiles for street cars. The improved cornering characteristics are offset by the substantially harsher ride and propensity towards rim damage, and on the performance Tesla I believe even 19" wheels will easily clear the brakes.
I fully agree, especially on an SUV or truck low profile tires are a joke. The Ride on most Sport SUVs is stiffened up already to try to correct for the higher center of gravity.
