Do I need to buy new winter tires/rims or can I somehow use the low profile winter tires on rims from my jaguar XJL. These are 20 inch ones.
Probably the rims and tire size are not compatible.
Not sure where you live but low profile tires are not the best for snow, more rubber gives more flex and grip. Mercedes with 20 inch tires for summer recommends 17 inch tires for winter ( naturally tire diameter has to be the same)
