Not yet -- I carry it because I&#x27;m required to have chains or an equivalent (the autosock counts) in the vehicle when driving into the mountains in Washington state and British Columbia during winter. Since the Tesla (P85D) is all wheel drive I&#x27;m not actually required to <i>use</i> the equivalent as long as I have M+S rated tires on the car.<p>For the past couple winters conditions have not demanded anything beyond the AWD and the tires. This is also an unfortunate commentary on the snow situation for the last couple winters.<p>I picked the autosock over chains as the Tesla owners manual advises against most change due to risk of damaging the wheel wells and body. There is apparently at least one model they&#x27;ve approved, which I&#x27;ll likely invest in the first time the autosock proves itself not up the task and forces me to turn back from a ski weekend.
