The new 2025 GT3RS's are wearing these Goodyears:
Eagle F1 Supersport RS. 80 Treadwear tires. Trying to see if they come on the ZL1 1LE sizes. I did see them somewhere in 305/30/R19s but not the 325 rears.
Edit:
"*The Goodyear Eagle F1 SuperSport RS tyres are designed to be used exclusively on the Porsche 911 GT2 RS models and the Porsche 911 GT3 RS models (991 series) and must not be used on any other vehicle type, including other Porsche models."
Maybe they'll do a version for Camaros/Vettes.
