I purchased a used 2016 Model S a couple of years ago and it is now time to replace the tires. In checking the sizes, the front are 245/45R 19 98W and the rear 245/45ZR 19 10RV. Another Tesla owner told me that I should have 19s on the front and 20s on the rear. In researching, it seems very confusing on what they should really be. These a Goodyear tires on it now. Can anyone tell me if it is okay to replace these with the same size of tires?
