"Well when you put it that way..."Why the heck would they deliver a decent sports car with crappy rubber that is not particularly good in any weather.
I think many would disagree about all-seasons being a bad thing. Also, many wouldn't call the Model S a sports car. A very sporty car I think we can all agree on.
Also, the 19s don't feel too bad (even compared to my 21 Conti) for daily driving... and the tread life (and hence TCO) is significantly improved.
