Hello,

I own a Xpeng G9 Performance V1 (551 hp, AWD). It comes stock with 21-inch wheels (255/45 R21).
I’m looking to invest in a complete winter wheel set, and I came across a listing for genuine Xpeng G9 wheels in 19 inches fitted with Pirelli Scorpion tires (photo attached). My manufacturer’s tire placard (driver’s door) does approve 255/55 R19 for my vehicle, so the size seems compatible on paper.

Has anyone actually tried this 21” → 19” downgrade on a G9 Performance specifically? I’m mainly wondering about:
• Brake caliper clearance
• Any rubbing or abnormal play when turning
• Ride/handling behavior with this narrower setup

Thanks in advance for your feedback!
