When You You Xue’s car was in Montreal getting new wheels at Fastco they weighed the optional 19” Sport wheel with the stock ContiPro RX. The combined weight was 48 lbs. The stock tire weighs 23 lbs. This leaves the optional 19” Sport wheel at approximately 25 lbs. with the TPMS/valve assembly. I’ll look for the link.

What’s most interesting is that the optional Tesla 19” Sport wheel/tire combo is actually
1 pound lighter than the stock Tesla 18” wheel/tire combo with the aero disc.
