    Has anyone been able to get any information about this? We have an extra set of 20 in wheels and tires that we have for our Sl500. I seem to remember someone saying that Tesla might use the same pattern. I would love to be able to swap back and forth between these and the stock 19's.

    I believe it was stated as 5x120 with 40mm offset

    I think you meant 40mm offset.

    No. They are monster truck wheels.

    I see Tire Rack has the 2013 Tesla Model S as a selectable model in their search engine, but no data or wheels come up yet. Step in the right direction.

    The wheel will need to have the correct centre-bore (which I don't know the dimensions of, but it appears wheels that fit BMW should work--meaning no one has actually tried it). On some cars the wheels are centered around the centre bore so getting the exact size is important. On other cars it's the bolt circle that the wheel is centered around so the centre bore just needs to be large enough to go over the hub. I don't know which of these the Model S uses.

    Also some wheels use a square nut and some use a chamfered nut. The pictures of the wheels look like they are chamfered (as are most wheels so that shouldn't be a problem).

    I believe the term you are looking for is "hub-centric" vs "lug-centric" wheels. Everything else you stated is spot on!

    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:smile:

    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.
