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. " from: Aftermarket wheels, specs and affects (not a range thread) I added the wheels specs to the FAQ for future reference. Model S - FAQ - Tesla Motors Club - Enthusiasts & Owners Forum
From the safety guide: 19 inch Front 8.0J x 19 Rear 8.0J x 19 21 inch - silver 21 inch - grey Front 8.5J x 21 Rear 8.5J x 21 Road wheel nut torque 175 Nm (129 lbf.ft) Tire specifications On 19 inch wheels: Goodyear Eagle RS-A2 All P245/45R19 98V On 21 inch wheels: Continental Extreme Contact DWS All P245/35R21 96Y
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.
