I've heard mixed things from tesla's very own service centers. I'm upgrading to Arachnids from stock 19's and one service center tech said that I would want to do a full alignment and balancing otherwise my steering would be "way off" after installation. Another tech said that since my car is practically brand new, I wouldn't need it for a year and the installation of different wheels wouldn't impact anything. Who is correct here? Any insight would be helpful... Thanks !!!
