The P85+ has different suspension components. Anyone know since the bushings (or other parts a s well) are different that they would ride more firm, percent wise, in the cold vs the standard bushings. I assume any car rides firmer in the cold but how much probably depends on the suspension/tires . I have not driven any Model S in colder temperatures. Since I'm pondering to drive the Tesla in the winter and was considering the P85 and the P85+, I'm concerned that the P+ might be too firm. I'd definitely use 19 winter tires. I have driven a P85+ in May with Winter 21 inch tires and it had a very firm ride.
