Wheel Bolt Pattern?

[jerry33]

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

Call it force-of-habit.

Those are bearly wheels.

Those are bearly wheels.

I thought they were HUG-centric

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.

Thanks a lot for the info, Jerry33!

I found a tire size comparion at discounttire.com where you can put in your sizes

here are the specs for the tesla OEM tires

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.
