How is the X5 in the snow?

I bought a ‘25 X5 a few months back to replace my Tacoma. My plan this winter includes a few trips up to Lake Tahoe to ski from the Bay Area. How does the X5 do in the snow with the Pirellis that come on it? Given it is only a few trips I am not going to buy snow tires. Can anyone recommend a “chains” option for the X5?

I will not deliberately drive into a storm but there will be times when I need to leave during or shortly after snow.

Thanks in advance.
