Hi All - I'm ordering a tire rack)set of winter wheels/tires for the Model S - have selected the bridgestone blizzaks for the tires, and am looking for some advice on the best offset for the wheels. Am planning on going with a square set of 20x8.5s and the options seem to be an offset of 35 or 30. Would the 35s look too 'sunk in' or recessed (more than stock? - I have the 21inch sonic carbon turbines). Any advice on which offset to go for would be much appreciated, and if anyone has any tire rack favorite winter wheels, please do share! Thanks very much, and happy new year to all!
