I'm seriously thinking of leasing a low mileage 2015 or 2016 Model S P90D which is a Tesla demo car. I've read a lot about issues with 21 inch wheels/tires and while they look great, it sounds like many people have problems with damaging the wheels, getting flats, etc, etc. As much as I would like to get a P90D with 19 inch wheels, there are very few available. I'm thinking of leasing the car with the 21 inch wheels/tires, but then taking them off the car and putting them in storage, with the intent to put them back on at the end of the lease. I'm looking for some advice and suggestions about where to purchase 19 inch Tesla wheels and which tires you might recommend. I'm more interested in tire life than the look of the wheels or tires. Please let me know the best place to purchase Tesla 19 inch wheels and your recommendations on the specific tires. I assume there are no safety issues with replacing the 21 inch with 19 inch? Thanks!
