Am I taking crazy pills or is one of those backwards? Tread should mirror each other. On each side.
Well mine is an AWD... not sure why that'd matter, but I have an appointment with Tesla to put on my winter wheels along with address some other things so I'll ask them for guidance on this.
Unless you're going to go WAY up the food chain at Tesla (to the R&D level!), I wouldn't trust what (most? some?) anyone at a Tesla Service Center would have to say about this.
I'd trust 1) Continental 2) TireRack/Discount Tire 3) Tesla Service Center...in that order.
