Deviating from OEM Tire Dimensions

Hi there,

It's time for me to replace the OEM tires on my MS. Because I live in Canada (Vancouver), I've been looking at getting All Weather (not All Season) tires as they are a nice hybrid between winter and all season tires. Plus my local insurer willnto cover winter accidents if I don't have the 3 peak mountain snowflake.

The problem I'm facing is that the OEM tires are 245/45 R19 and there is a very limited selection of All-Weather tires in that size. One of the local tire shops (Fountain Tire) has said they can find for me a good set of Goodyear WeatherReady All-Weather tires in 235/50 R19. They said that this will result in the new tires being a 14mm difference from the old ones (7mm on the bottom and 7mm closer to the suspension). Also note that I have an active suspension which I do use since I need to be at my very high ride height to get up my driveway without rubbing. I'm wondering if that height difference is going to pose a problem or not. Tesla doesn't seem to have any publicly available info that I can find, so I'm turning to the TMC hive mind to help me.

Any advice, folks? Will putting a 235/50 tire cause problems? Will it rub against the suspension?

Thanks!
