    Usually people don't understand hub-centric and lug-centric (not this forum's members) so I end up explaining what the terms mean anyway

    Call it force-of-habit.

    I too am considering going with 20" wheels (prob 245/40ZR20). Any idea when the speedometer needs to be recalibrated if there is a substantial difference in revs per mile (+/- 20 or so?) with the new tires? Looks like we've got the aftermarket rim specs figured out...

    Just divide the RPM of the candidate tire by the RPM of the OE tire and come up with a percentage. It shouldn't be more than 2% higher or 5% lower.

    So would the wheels that were shown previously work?

    Also, TireRack has a number of tire options as a former post noted. My main question is: are the available replacement tires low-rolling resistant tires? I would think that the OEM tires are LRR in order to increase range.

    Thoughts?

    Tesla chose performance tire sizes that have almost no LRR tires. The only one I've found so far is the winter tire Nokian Hakkapeliitta R: "The new Hakkapeliitta R has the lowest rolling resistance of any tire in Nokian Tyres product line." Why Tesla didn't design the Model S so that it could have sensibly sized tires/wheels where LRR is common--only as an option for those that want it--is beyond me.
