Brooks with DTs is going to weight them for us.
I'll be doing a complete tire/wheel weight breakdown in addition to suspension (especially camber) analysis with pics when I get my car.
Based on AMGF's wheel/tire weights plus the Mich web site
Front rims weigh 60-28.2 or 31.8 lbs
Rear rims weigh 65.4 - 30 or 35.4 lbs
These are of course for the only wheel/tires currently being delivered Arachnid 21s
If accurate, there is a lot of ride quality, handling, accelerating and braking performance to be had using aftermarket rims. A lot of the flow formed rims provide significantly lower weights and still come in less than $4,500 inclusive of Sport 4S tires and TPMS. It's a shame Tesla can not get the 19" fitment sorted so owners can buy better performing rims with their $4,500.
I put these on my 2015 for a 10 lb per corner savings and for just over half the $4,500 Tesla option price.
