The GT model derates from 270 mile range of AWD Premium to 250 mile range on GT.

Biggest difference would seem to be the 20" wheels vs. the Premiums 19" to the Selects 18".

Would putting a high efficiency 18" wheel and tire combo get the GT up to the 270 mile range?

"Wheel diameter can also make a big difference. Using coast-down resistance data Tesla submits to the EPA for efficiency testing, Fenske calculated that the range of a Model 3 Performance driven at a consist 75 mph was about 40 miles less with 20-inch wheels than with 18-inch wheels. Smaller—bit still significant—differences were shown for the Model S Performance and Model X Performance as well."

GT is standard with 20" 245/45/R20 vs. 18" 235/40/R18 standard. Big difference. Should be able to get the 30 miles back, get 270 range on GT with 18"
