Traded in the R1S Quad (‘23) for a Dual S (‘26), came with the GY TAT (RIV) tires on 20” rims.
QM - Quad motor (~130 kWh pack)
DM - Dual motor (91 kWh pack)
Treadwear

c-concrete (otherwise asphalt)
Update after 600 miles:
front tires appear to be wearing quickly, around 1/32 per 2,000 miles, suggesting <20,000 miles …not sure that’s very accurate, will check again in a month or two…
Trip B - 150 miles - 2.37 MPK (before reset; 35 mph average)
