I have reserved a 2016 CPO 90D X and the pictures show the front tires are Continental and the rear tires are Nexen. I wanted to get some opinions as to how hard I should push on Tesla to get matching tires on it before I buy it. I've heard with AWD vehicles you want to keep the tires the same and as close to the same tread as possible but I'm not sure if this is still important with a Tesla or not.
