Can you install 21-inch Arachnids staggered wheels on a 75D that came with 19" standard wheels?

    Yes... you just have to select the 21 option when relearning TPMS and you should probably get the car re-aligned after installation.

    Yes but you will lose range ~15% ..since you have smaller battery that will suck ...although 21s look the best on an S :);)

    I'd expect some range loss--but is it really as much as 15%, how come so much?

    yes its that much sometimes more... i had 21s on both my S (P85+, P85D) and consistently saw that drop off driving over 80k miles.. on tesla website that is what they state as well.. its due to increased weight of wheels/tires .. greater rolling resistance.....since you have a smaller battery and live in area where roads probably not as good maybe good option is look at Tsportline 20s .. they look nice and are lighter... the stock 21s are just really heavy.. although they do look nice :eek:

    Arachnids are supposed to be the lightest of the 21” sets no?

    I know I know...it’s also about rolling resistance lol.

    They are not as light as the 19s :(...if you don’t drive far than it’s probably a non issue ..the issue than becomes like other poster mentioned u can’t rotate ..I found on my P85D I was getting 15k miles max in my staggered 21s. 21s are also limited in tire selection ...my X with 22s is cheaper to find tire replacement with more selection ..that said I would never put 19s on my S :eek:

    The standard 19s weigh about 35# with tires while the 21s (non-arachnids) weigh about 65# with tires.

    A lot of misinformation has been posted here :cool:

    My current Model S with 21" Arachnid wheels gets the same range compared to my 19" OEM wheels.
    The Tesla forged 21" Arachnid wheels are lighter and stronger than both the 21" and 19" OEM wheels.

    For the record: The Tesla Model S Wheel Guide

    19" Model S Base Wheel
    • Size: 19X8.0"
    • Weight: 29.5 lbs
    21" Turbine Wheel
    • Size: 21X8.5"
    • Weight: 21x8.5" = ~35.2 lbs, 21x9.0" = ~38 lbs
    21" Arachnid Wheel
    • Size: 21X8.5" front, 21X9.0" rear.
    • Weight: 21x8.5" = 27.85 lbs, 21x9.0" = ~ 28.75 lbs

    I don't think that's true. I recently went from OEM 19" to AG F221 20" and carrying those 19" with tires was definitely more than 35 lbs each. They felt slightly heavier even than my AG F221 20" with tires.
