Do 20" 970 wheels fit the 971?
 

Just bought a 2018 4S (but haven't taken delivery yet). Have an extra set of OEM 20" 911 Turbo II wheels from my former 2012 P4 that I'd like to use as winter wheels. TireRack shows that standard tire sizes for 2018 971's with 20" wheels are Front: 275/40-20, Rear: 315/35-20. 970 Panameras with 20" wheels were: Front: 255/40-20, Rear: 285/35-20. I'm going to have to buy new snow tires for all 4 wheels - is there any way I can make it work? Are the TPMS sensors compatible, or will I need new ones?

Thanks!
