    Would like to know so that I can switch out the 21in performance wheels for a more comfortable 19in with possible wider tires for more rear grip :)

    "OEM specs: 5x120 bolt pattern, 40mm offset, 64mm centerbore, hubcentric, M14x1.5 lugs with 170 N/m torque; per Jerry 33 (our resident wheel expert), don't want more than +/- 4mm on the new offset or +/- 2% on the revs/mile (anything more would prob need your speedometer/odometer calibrated) "

    from: Aftermarket wheels, specs and affects (not a range thread)

    The 19's are 19x8. I searched the forum for 21x and turned up nothing, so I can't tell you what the width is on the 21's...

    Weights:
    19" Wheels: 13.74kg ~30lbs each (according to a Tesla engineer)
    Tires: 27lbs each (according to Tire Rack for Eagle RS-A2 245/45 19")"
    from: Weight of 19 Wheels and Tires


    21" Wheels: "the 21" wheels with Continental ExtremeContact DW tires weigh 61 pounds. Tirerack says those tires weigh 26 pounds, so the 21" wheels must be 35 pounds. "

    I added the wheels specs to the FAQ for future reference. Model S - FAQ - Tesla Motors Club - Enthusiasts & Owners Forum

    Please note that this is a typo from Tesla. The front and rear wheels are the same for 19". They are almost certainly 8.0Jx 19.
